If the script uses different encoding then you can convert those texts with PHP's iconv() or mb_convert_encoding() functions. + +##### PHP complains about ZipArchive not being found + +Make sure you meet all requirements, especially php_zip extension should be enabled. + +The ZipArchive class is only required when reading or writing formats that use Zip compression (Excel2007 and OOCalc). Since version 1.7.6 the PCLZip library has been bundled with PHPExcel as an alternative to the ZipArchive class. + +This can be enabled by calling: +```php +PHPExcel_Settings::setZipClass(PHPExcel_Settings::PCLZIP); +``` +*before* calling the save method of the Excel2007 Writer. + +You can revert to using ZipArchive by calling: +```php +PHPExcel_Settings::setZipClass(PHPExcel_Settings::ZIPARCHIVE); +``` +At present, this only allows you to write Excel2007 files without the need for ZipArchive (not to read Excel2007 or OOCalc) + +##### Excel 2007 cannot open the file generated by PHPExcel_Writer_2007 on Windows + +*"Excel found unreadable content in '*.xlsx'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes."* + +Some older versions of the 5.2.x php_zip extension on Windows contain an error when creating ZIP files. The version that can be found on [http://snaps.php.net/win32/php5.2-win32-latest.zip][8] should work at all times. + +Alternatively, upgrading to at least PHP 5.2.9 should solve the problem. + +If you can't locate a clean copy of ZipArchive, then you can use the PCLZip library as an alternative when writing Excel2007 files, as described above. + +##### Fatal error: Allowed memory size of xxx bytes exhausted (tried to allocate yyy bytes) in zzz on line aaa + +PHPExcel holds an "in memory" representation of a spreadsheet, so it is susceptible to PHP's memory limitations. The memory made available to PHP can be increased by editing the value of the memory_limit directive in your php.ini file, or by using ini_set('memory_limit', '128M') within your code (ISP permitting). + +Some Readers and Writers are faster than others, and they also use differing amounts of memory. You can find some indication of the relative performance and memory usage for the different Readers and Writers, over the different versions of PHPExcel, on the [discussion board][9]. + +If you've already increased memory to a maximum, or can't change your memory limit, then [this discussion][10] on the board describes some of the methods that can be applied to reduce the memory usage of your scripts using PHPExcel. + +##### Protection on my worksheet is not working? + +When you make use of any of the worksheet protection features (e.g. cell range protection, prohibiting deleting rows, ...), make sure you enable worksheet security. This can for example be done like this: +```php +$objPHPExcel->getActiveSheet()->getProtection()->setSheet(true); +``` + +##### Feature X is not working with PHPExcel_Reader_Y / PHPExcel_Writer_Z + +Not all features of PHPExcel are implemented in all of the Reader / Writer classes. This is mostly due to underlying libraries not supporting a specific feature or not having implemented a specific feature. + +For example autofilter is not implemented in PEAR Spreadsheet_Excel_writer, which is the base of our Excel5 writer. + +We are slowly building up a list of features, together with the different readers and writers that support them, in the "Functionality Cross-Reference.xls" file in the /Documentation folder. + +##### Formulas don't seem to be calculated in Excel2003 using compatibility pack? + +This is normal behaviour of the compatibility pack, Excel2007 displays this correctly. Use PHPExcel_Writer_Excel5 if you really need calculated values, or force recalculation in Excel2003. + +##### Setting column width is not 100% accurate + +Trying to set column width, I experience one problem. When I open the file in Excel, the actual width is 0.71 less than it should be. + +The short answer is that PHPExcel uses a measure where padding is included.

It is only necessary to include the initial PHPExcel class file, then the autoloader will include other class files as and when required, so only those files that are actually required by your script will be loaded into PHP memory. The main benefit of this is that it reduces the memory footprint of PHPExcel itself, so that it uses less PHP memory. + +If your own scripts already define an autoload function, then this may be overwritten by the PHPExcel autoload function. For example, if you have: +```php +function __autoload($class) { + ... +} +``` +Do this instead: +```php +function myAutoload($class) { + ... +} + +spl_autoload_register('myAutoload'); +``` +Your autoloader will then co-exist with the autoloader of PHPExcel. + +### Spreadsheet in memory + +PHPExcel's architecture is built in a way that it can serve as an in-memory spreadsheet. This means that, if one would want to create a web based view of a spreadsheet which communicates with PHPExcel's object model, he would only have to write the front-end code. + +Just like desktop spreadsheet software, PHPExcel represents a spreadsheet containing one or more worksheets, which contain cells with data, formulas, images, ... + +### Readers and writers + +On its own, PHPExcel does not provide the functionality to read from or write to a persisted spreadsheet (on disk or in a database). To provide that functionality, readers and writers can be used. + +By default, the PHPExcel package provides some readers and writers, including one for the Open XML spreadsheet format (a.k.a. Excel 2007 file format). You are not limited to the default readers and writers, as you are free to implement the PHPExcel_Writer_IReader and PHPExcel_Writer_IWriter interface in a custom class. + +### Fluent interfaces + +PHPExcel supports fluent interfaces in most locations. This means that you can easily "chain"" calls to specific methods without requiring a new PHP statement. For example, take the following code: +```php +$objPHPExcel->getProperties()->setCreator("Maarten Balliauw"); +$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw"); +$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document"); +$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document"); +$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes."); +$objPHPExcel->getProperties()->setKeywords("office 2007 openxml php"); +$objPHPExcel->getProperties()->setCategory("Test result file"); +``` +This can be rewritten as: +```php +$objPHPExcel->getProperties() + ->setCreator("Maarten Balliauw") + ->setLastModifiedBy("Maarten Balliauw") + ->setTitle("Office 2007 XLSX Test Document") + ->setSubject("Office 2007 XLSX Test Document") + ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.") + ->setKeywords("office 2007 openxml php") + ->setCategory("Test result file"); +``` + +__Using fluent interfaces is not required__ +Fluent interfaces have been implemented to provide a convenient programming API. Use of them is not required, but can make your code easier to read and maintain. It can also improve performance, as you are reducing the overall number of calls to PHPExcel methods. diff --git a/Documentation/markdown/Overview/developer.md b/Documentation/markdown/Overview/developer.md new file mode 100644 index 00000000..7030eaae --- /dev/null +++ b/Documentation/markdown/Overview/developer.md @@ -0,0 +1,3050 @@ +# PHPExcel Developer Documentation + + +## 1.

It is only necessary to include the initial PHPExcel class file, then the autoloader will include other class files as and when required, so only those files that are actually required by your script will be loaded into PHP memory. The main benefit of this is that it reduces the memory footprint of PHPExcel itself, so that it uses less PHP memory. + +If your own scripts already define an autoload function, then this may be overwritten by the PHPExcel autoload function. For example, if you have: + +function __autoload($class) { + +... + +} + +Do this instead: + +function myAutoload($class) { + +... + +} + +spl_autoload_register('myAutoload'); + +Your autoloader will then co-exist with the autoloader of PHPExcel. + +## Spreadsheet in memory + +PHPExcel’s architecture is built in a way that it can serve as an in-memory spreadsheet. This means that, if one would want to create a web based view of a spreadsheet which communicates with PHPExcel’s object model, he would only have to write the front-end code. + +Just like desktop spreadsheet software, PHPExcel represents a spreadsheet containing one or more worksheets, which contain cells with data, formulas, images, … + +## Readers and writers + +On its own, PHPExcel does not provide the functionality to read from or write to a persisted spreadsheet (on disk or in a database). To provide that functionality, readers and writers can be used. + +By default, the PHPExcel package provides some readers and writers, including one for the Open XML spreadsheet format (a.k.a. Excel 2007 file format). You are not limited to the default readers and writers, as you are free to implement the PHPExcel_Writer_IReader and PHPExcel_Writer_IWriter interface in a custom class. + + + +## Fluent interfaces + +PHPExcel supports fluent interfaces in most locations. This means that you can easily “chain” calls to specific methods without requiring a new PHP statement. For example, take the following code: + +$objPHPExcel->getProperties()->setCreator("Maarten Balliauw"); + +$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw"); + +$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document"); + +$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document"); + +$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes."); + +$objPHPExcel->getProperties()->setKeywords("office 2007 openxml php"); + +$objPHPExcel->getProperties()->setCategory("Test result file"); + +This can be rewritten as: + +$objPHPExcel->getProperties() + ->setCreator("Maarten Balliauw") + +->setLastModifiedBy("Maarten Balliauw") + +->setTitle("Office 2007 XLSX Test Document") + +->setSubject("Office 2007 XLSX Test Document") + +->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.") + +->setKeywords("office 2007 openxml php") + +->setCategory("Test result file"); + +__Using fluent interfaces is not required__ +Fluent interfaces have been implemented to provide a convenient programming API. Use of them is not required, but can make your code easier to read and maintain. It can also improve performance, as you are reducing the overall number of calls to PHPExcel methods. + +# Creating a spreadsheet + +## The PHPExcel class + +The PHPExcel class is the core of PHPExcel. It contains references to the contained worksheets, document security settings and document meta data. + +To simplify the PHPExcel concept: the PHPExcel class represents your workbook. + +Typically, you will create a workbook in one of two ways, either by loading it from a spreadsheet file, or creating it manually. A third option, though less commonly used, is cloning an existing workbook that has been created using one of the previous two methods. + +### Loading a Workbook from a file + +Details of the different spreadsheet formats supported, and the options available to read them into a PHPExcel object are described fully in the “PHPExcel User Documentation - Reading Spreadsheet Files” document. + + +$inputFileName = './sampleData/example1.xls'; + +/** Load $inputFileName to a PHPExcel Object **/ +$objPHPExcel = PHPExcel_IOFactory::load($inputFileName); + + +### Creating a new workbook + +If you want to create a new workbook, rather than load one from file, then you simply need to instantiate it as a new PHPExcel object. + + +/** Create a new PHPExcel Object **/ +$objPHPExcel = new PHPExcel(); + + +A new workbook will always be created with a single worksheet. + +## Configuration Settings + +Once you have included the PHPExcel files in your script, but before instantiating a PHPExcel object or loading a workbook file, there are a number of configuration options that can be set which will affect the subsequent behaviour of the script. + +### Cell Caching + +PHPExcel uses an average of about 1k/cell in your worksheets, so large workbooks can quickly use up available memory. Cell caching provides a mechanism that allows PHPExcel to maintain the cell objects in a smaller size of memory, on disk, or in APC, memcache or Wincache, rather than in PHP memory. This allows you to reduce the memory usage for large workbooks, although at a cost of speed to access cell data. + +By default, PHPExcel still holds all cell objects in memory, but you can specify alternatives. To enable cell caching, you must call the PHPExcel_Settings::setCacheStorageMethod() method, passing in the caching method that you wish to use. + +$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_in_memory; + +PHPExcel_Settings::setCacheStorageMethod($cacheMethod); + +setCacheStorageMethod() will return a boolean true on success, false on failure (for example if trying to cache to APC when APC is not enabled). + +A separate cache is maintained for each individual worksheet, and is automatically created when the worksheet is instantiated based on the caching method and settings that you have configured. You cannot change the configuration settings once you have started to read a workbook, or have created your first worksheet. + +Currently, the following caching methods are available. + +PHPExcel_CachedObjectStorageFactory::cache_in_memory; + +The default. If you don’t initialise any caching method, then this is the method that PHPExcel will use. Cell objects are maintained in PHP memory as at present. + +PHPExcel_CachedObjectStorageFactory::cache_in_memory_serialized; + +Using this caching method, cells are held in PHP memory as an array of serialized objects, which reduces the memory footprint with minimal performance overhead. + +PHPExcel_CachedObjectStorageFactory::cache_in_memory_gzip; + +Like cache_in_memory_serialized, this method holds cells in PHP memory as an array of serialized objects, but gzipped to reduce the memory usage still further, although access to read or write a cell is slightly slower. + +PHPExcel_CachedObjectStorageFactory::cache_igbinary; + +Uses PHP’s igbinary extension (if it’s available) to serialize cell objects in memory. This is normally faster and uses less memory than standard PHP serialization, but isn’t available in most hosting environments. + +PHPExcel_CachedObjectStorageFactory::cache_to_discISAM; + +When using cache_to_discISAM all cells are held in a temporary disk file, with only an index to their location in that file maintained in PHP memory. This is slower than any of the cache_in_memory methods, but significantly reduces the memory footprint. By default, PHPExcel will use PHP’s temp directory for the cache file, but you can specify a different directory when initialising cache_to_discISAM. + +$cacheMethod = PHPExcel_CachedObjectStorageFactory:: cache_to_discISAM; + +$cacheSettings = array( 'dir' => '/usr/local/tmp' + +); + +PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings); + +The temporary disk file is automatically deleted when your script terminates. + +PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp; + +Like cache_to_discISAM, when using cache_to_phpTemp all cells are held in the php://temp I/O stream, with only an index to their location maintained in PHP memory. In PHP, the php://memory wrapper stores data in the memory: php://temp behaves similarly, but uses a temporary file for storing the data when a certain memory limit is reached. The default is 1 MB, but you can change this when initialising cache_to_phpTemp. + +$cacheMethod = PHPExcel_CachedObjectStorageFactory:: cache_to_phpTemp; + +$cacheSettings = array( 'memoryCacheSize' => '8MB' + +); + +PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings); + +The php://temp file is automatically deleted when your script terminates. + +PHPExcel_CachedObjectStorageFactory::cache_to_apc; + +When using cache_to_apc, cell objects are maintained in APC with only an index maintained in PHP memory to identify that the cell exists. By default, an APC cache timeout of 600 seconds is used, which should be enough for most applications: although it is possible to change this when initialising cache_to_APC. + +$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_APC; + +$cacheSettings = array( 'cacheTime' => 600 + +); + +PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings); + +When your script terminates all entries will be cleared from APC, regardless of the cacheTime value, so it cannot be used for persistent storage using this mechanism. + +PHPExcel_CachedObjectStorageFactory::cache_to_memcache + +When using cache_to_memcache, cell objects are maintained in memcache with only an index maintained in PHP memory to identify that the cell exists. + +By default, PHPExcel looks for a memcache server on localhost at port 11211. It also sets a memcache timeout limit of 600 seconds. If you are running memcache on a different server or port, then you can change these defaults when you initialise cache_to_memcache: + +$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_memcache; + +$cacheSettings = array( 'memcacheServer' => 'localhost', + +'memcachePort' => 11211, + +'cacheTime' => 600 + +); + +PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings); + +When your script terminates all entries will be cleared from memcache, regardless of the cacheTime value, so it cannot be used for persistent storage using this mechanism. + +PHPExcel_CachedObjectStorageFactory::cache_to_wincache; + +When using cache_to_wincache, cell objects are maintained in Wincache with only an index maintained in PHP memory to identify that the cell exists. By default, a Wincache cache timeout of 600 seconds is used, which should be enough for most applications: although it is possible to change this when initialising cache_to_wincache. + +$cacheMethod = PHPExcel_CachedObjectStorageFactory::cache_to_wincache; + +$cacheSettings = array( 'cacheTime' => 600 + +); + +PHPExcel_Settings::setCacheStorageMethod($cacheMethod, $cacheSettings); + +When your script terminates all entries will be cleared from Wincache, regardless of the cacheTime value, so it cannot be used for persistent storage using this mechanism. + +PHPExcel_CachedObjectStorageFactory::cache_to_sqlite; + +Uses an SQLite 2 in-memory database for caching cell data. Unlike other caching methods, neither cells nor an index are held in PHP memory - an indexed database table makes it unnecessary to hold any index in PHP memory – making this the most memory-efficient of the cell caching methods. + +PHPExcel_CachedObjectStorageFactory::cache_to_sqlite3; + +Uses an SQLite 3 in-memory database for caching cell data. Unlike other caching methods, neither cells nor an index are held in PHP memory - an indexed database table makes it unnecessary to hold any index in PHP memory – making this the most memory-efficient of the cell caching methods. + +### Language/Locale + +Some localisation elements have been included in PHPExcel. You can set a locale by changing the settings. To set the locale to Brazilian Portuguese you would use: + +$locale = 'pt_br'; + +$validLocale = PHPExcel_Settings::setLocale($locale); + +if (!$validLocale) { + +echo 'Unable to set locale to '.$locale." - reverting to en_us
\n"; + +} + +If Brazilian Portuguese language files aren’t available, then the Portuguese will be enabled instead: if Portuguese language files aren’t available, then the setLocale() method will return an error, and American English (en_us) settings will be used throughout. + +More details of the features available once a locale has been set, including a list of the languages and locales currently supported, can be found in section REF _Ref259954895 \r \h 4.5.5 REF _Ref259954904 \h Locale Settings for Formulae. + +## Clearing a Workbook from memory + +The PHPExcel object contains cyclic references (e.g. the workbook is linked to the worksheets, and the worksheets are linked to their parent workbook) which cause problems when PHP tries to clear the objects from memory when they are unset(), or at the end of a function when they are in local scope. The result of this is “memory leaks”, which can easily use a large amount of PHP’s limited memory. + +This can only be resolved manually: if you need to unset a workbook, then you also need to “break” these cyclic references before doing so. PHPExcel provides the disconnectWorksheets() method for this purpose. + +$objPHPExcel->disconnectWorksheets(); + +unset($objPHPExcel); + +## Worksheets + +A worksheet is a collection of cells, formula’s, images, graphs, … It holds all data necessary to represent as a spreadsheet worksheet. + +When you load a workbook from a spreadsheet file, it will be loaded with all its existing worksheets (unless you specified that only certain sheets should be loaded). When you load from non-spreadsheet files (such as a CSV or HTML file) or from spreadsheet formats that don’t identify worksheets by name (such as SYLK), then a single worksheet called “WorkSheet” will be created containing the data from that file. + +When you instantiate a new workbook, PHPExcel will create it with a single worksheet called “WorkSheet”. + +The getSheetCount() method will tell you the number of worksheets in the workbook; while the getSheetNames() method will return a list of all worksheets in the workbook, indexed by the order in which their “tabs” would appear when opened in MS Excel (or other appropriate Spreadsheet program). + +Individual worksheets can be accessed by name, or by their index position in the workbook. The index position represents the order that each worksheet “tab” is shown when the workbook is opened in MS Excel (or other appropriate Spreadsheet program). To access a sheet by its index, use the getSheet() method. + +// Get the second sheet in the workbook + +// Note that sheets are indexed from 0 + +$objPHPExcel->getSheet(1); + +If you don’t specify a sheet index, then the first worksheet will be returned. + +Methods also exist allowing you to reorder the worksheets in the workbook. + +To access a sheet by name, use the getSheetByName() method, specifying the name of the worksheet that you want to access. + +// Retrieve the worksheet called 'Worksheet 1' + +$objPHPExcel->getSheetByName('Worksheet 1'); + +Alternatively, one worksheet is always the currently active worksheet, and you can access that directly. The currently active worksheet is the one that will be active when the workbook is opened in MS Excel (or other appropriate Spreadsheet program). + +// Retrieve the current active worksheet + +$objPHPExcel->getActiveSheet(); + +You can change the currently active sheet by index or by name using the setActiveSheetIndex() and setActiveSheetIndexByName()methods. + +### Adding a new Worksheet + +You can add a new worksheet to the workbook using the createSheet() method of the PHPExcel object. By default, this will be created as a new “last” sheet; but you can also specify an index position as an argument, and the worksheet will be inserted at that position, shuffling all subsequent worksheets in the collection down a place. + +$objPHPExcel->createSheet(); + +A new worksheet created using this method will be called “Worksheet” or “Worksheet” where “” is the lowest number possible to guarantee that the title is unique. + +Alternatively, you can instantiate a new worksheet (setting the title to whatever you choose) and then insert it into your workbook using the addSheet() method. + +// Create a new worksheet called “My Data” + +$myWorkSheet = new PHPExcel_Worksheet($objPHPExcel, 'My Data'); + +// Attach the “My Data” worksheet as the first worksheet in the PHPExcel object + +$objPHPExcel->addSheet($myWorkSheet, 0); + +If you don’t specify an index position as the second argument, then the new worksheet will be added after the last existing worksheet. + +### Copying Worksheets + +Sheets within the same workbook can be copied by creating a clone of the worksheet you wish to copy, and then using the addSheet() method to insert the clone into the workbook. + +$objClonedWorksheet = clone $objPHPExcel->getSheetByName('Worksheet 1'); + +$objClonedWorksheet->setTitle('Copy of Worksheet 1') + +$objPHPExcel->addSheet($objClonedWorksheet); + +You can also copy worksheets from one workbook to another, though this is more complex as PHPExcel also has to replicate the styling between the two workbooks. The addExternalSheet() method is provided for this purpose. + +$objClonedWorksheet = clone $objPHPExcel1->getSheetByName('Worksheet 1'); + +$objPHPExcel->addExternalSheet($objClonedWorksheet); + +In both cases, it is the developer’s responsibility to ensure that worksheet names are not duplicated. PHPExcel will throw an exception if you attempt to copy worksheets that will result in a duplicate name. + +### Removing a Worksheet + +You can delete a worksheet from a workbook, identified by its index position, using the removeSheetByIndex() method + +$sheetIndex = $objPHPExcel->getIndex($objPHPExcel-> getSheetByName('Worksheet 1')); + +$objPHPExcel->removeSheetByIndex($sheetIndex); + +If the currently active worksheet is deleted, then the sheet at the previous index position will become the currently active sheet. + +## Accessing cells + +Accessing cells in a PHPExcel worksheet should be pretty straightforward. This topic lists some of the options to access a cell. + +### Setting a cell value by coordinate + +Setting a cell value by coordinate can be done using the worksheet’s setCellValue method. + +$objPHPExcel->getActiveSheet()->setCellValue('B8', 'Some value'); + +### Retrieving a cell by coordinate + +To retrieve the value of a cell, the cell should first be retrieved from the worksheet using the getCell method. A cell’s value can be read again using the following line of code: + +$objPHPExcel->getActiveSheet()->getCell('B8')->getValue(); + +If you need the calculated value of a cell, use the following code. This is further explained in REF _Ref191885372 \w \h \* MERGEFORMAT 4.4.35. + +$objPHPExcel->getActiveSheet()->getCell('B8')->getCalculatedValue(); + +### Setting a cell value by column and row + +Setting a cell value by coordinate can be done using the worksheet’s setCellValueByColumnAndRow method. + +// Set cell B8 +$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow(1, 8, 'Some value'); + +### Retrieving a cell by column and row + +To retrieve the value of a cell, the cell should first be retrieved from the worksheet using the getCellByColumnAndRow method.

This is further explained in REF _Ref191885372 \w \h 4.4.35 + +// Get cell B8 +$objPHPExcel->getActiveSheet()->getCellByColumnAndRow(1, 8)->getCalculatedValue(); + +### Looping cells + +#### Looping cells using iterators + +The easiest way to loop cells is by using iterators. Using iterators, one can use foreach to loop worksheets, rows and cells. + +Below is an example where we read all the values in a worksheet and display them in a table. + +setReadDataOnly(true); + +$objPHPExcel = $objReader->load("test.xlsx"); + +$objWorksheet = $objPHPExcel->getActiveSheet(); + +echo '' . "\n"; + +foreach ($objWorksheet->getRowIterator() as $row) { + +echo '' . "\n"; + +$cellIterator = $row->getCellIterator(); + +$cellIterator->setIterateOnlyExistingCells(false); // This loops all cells, + // even if it is not set. + // By default, only cells + // that are set will be + // iterated. + +foreach ($cellIterator as $cell) { + +echo '' . "\n"; + +} + +echo '' . "\n"; + +} + +echo '
' . $cell->getValue() . '
' . "\n"; +?> + +Note that we have set the cell iterator’s setIterateOnlyExistingCells() to false. This makes the iterator loop all cells, even if they were not set before. + +__The cell iterator will return ____null____ as the cell if it is not set in the worksheet.__ +Setting the cell iterator’s setIterateOnlyExistingCells()to false will loop all cells in the worksheet that can be available at that moment. This will create new cells if required and increase memory usage! Only use it if it is intended to loop all cells that are possibly available. + +#### Looping cells using indexes + +One can use the possibility to access cell values by column and row index like (0,1) instead of 'A1' for reading and writing cell values in loops. + +Note: In PHPExcel column index is 0-based while row index is 1-based. That means 'A1' ~ (0,1) + +Below is an example where we read all the values in a worksheet and display them in a table. + +setReadDataOnly(true); + +$objPHPExcel = $objReader->load("test.xlsx"); + +$objWorksheet = $objPHPExcel->getActiveSheet(); + +$highestRow = $objWorksheet->getHighestRow(); // e.g. 10 + +$highestColumn = $objWorksheet->getHighestColumn(); // e.g 'F' + +$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn); // e.g. 5 + +echo '' . "\n"; + +for ($row = 1; $row <= $highestRow; ++$row) { + +echo '' . "\n"; + +for ($col = 0; $col <= $highestColumnIndex; ++$col) { + +echo '' . "\n"; + +} + +echo '' . "\n"; + +} + +echo '
' . $objWorksheet->getCellByColumnAndRow($col, $row)->getValue() . '
' . "\n"; + +?> + +### Using value binders to facilitate data entry + +Internally, PHPExcel uses a default PHPExcel_Cell_IValueBinder implementation (PHPExcel_Cell_DefaultValueBinder) to determine data types of entered data using a cell’s setValue() method. + +Optionally, the default behaviour of PHPExcel can be modified, allowing easier data entry. For example, a PHPExcel_Cell_AdvancedValueBinder class is present. It automatically converts percentages and dates entered as strings to the correct format, also setting the cell’s style information. The following example demonstrates how to set the value binder in PHPExcel: + +/** PHPExcel */ + +require_once 'PHPExcel.php'; + +/** PHPExcel_Cell_AdvancedValueBinder */ + +require_once 'PHPExcel/Cell/AdvancedValueBinder.php'; + +/** PHPExcel_IOFactory */ + +require_once 'PHPExcel/IOFactory.php'; + +// Set value binder + +PHPExcel_Cell::setValueBinder( new PHPExcel_Cell_AdvancedValueBinder() ); + +// Create new PHPExcel object + +$objPHPExcel = new PHPExcel(); + +// ... + +// Add some data, resembling some different data types + +$objPHPExcel->getActiveSheet()->setCellValue('A4', 'Percentage value:'); + +$objPHPExcel->getActiveSheet()->setCellValue('B4', '10%'); + // Converts to 0.1 and sets percentage cell style + +$objPHPExcel->getActiveSheet()->setCellValue('A5', 'Date/time value:'); + +$objPHPExcel->getActiveSheet()->setCellValue('B5', '21 December 1983'); + // Converts to date and sets date format cell style + +__Creating your own value binder is easy____.__ +When advanced value binding is required, you can implement the PHPExcel_Cell_IValueBinder interface or extend the PHPExcel_Cell_DefaultValueBinder or PHPExcel_Cell_AdvancedValueBinder classes. + +## PHPExcel recipes + +The following pages offer you some widely-used PHPExcel recipes. Please note that these do NOT offer complete documentation on specific PHPExcel API functions, but just a bump to get you started. If you need specific API functions, please refer to the API documentation. + +For example, REF _Ref191885321 \w \h 4.4.7 REF _Ref191885321 \h Setting a worksheet’s page orientation and size covers setting a page orientation to A4. Other paper formats, like US Letter, are not covered in this document, but in the PHPExcel API documentation. + +### Setting a spreadsheet’s metadata + +PHPExcel allows an easy way to set a spreadsheet’s metadata, using document property accessors. Spreadsheet metadata can be useful for finding a specific document in a file repository or a document management system. For example Microsoft Sharepoint uses document metadata to search for a specific document in its document lists. + +Setting spreadsheet metadata is done as follows: + +$objPHPExcel->getProperties()->setCreator("Maarten Balliauw"); + +$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw"); + +$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document"); + +$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document"); + +$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes."); + +$objPHPExcel->getProperties()->setKeywords("office 2007 openxml php"); + +$objPHPExcel->getProperties()->setCategory("Test result file"); + +### Setting a spreadsheet’s active sheet + +The following line of code sets the active sheet index to the first sheet: + +$objPHPExcel->setActiveSheetIndex(0); + +### Write a date or time into a cell + +In Excel, dates and Times are stored as numeric values counting the number of days elapsed since 1900-01-01. For example, the date '2008-12-31' is represented as 39813. You can verify this in Microsoft Office Excel by entering that date in a cell and afterwards changing the number format to 'General' so the true numeric value is revealed. Likewise, '3:15 AM' is represented as 0.135417. + +PHPExcel works with UST (Universal Standard Time) date and Time values, but does no internal conversions; so it is up to the developer to ensure that values passed to the date/time conversion functions are UST. + +Writing a date value in a cell consists of 2 lines of code. Select the method that suits you the best. Here are some examples: + +/* PHPExcel_Cell_AdvanceValueBinder required for this sample */ + +require_once 'PHPExcel/Cell/AdvancedValueBinder.php'; + +// MySQL-like timestamp '2008-12-31' or date string + +PHPExcel_Cell::setValueBinder( new PHPExcel_Cell_AdvancedValueBinder() ); + +$objPHPExcel->getActiveSheet() + +->setCellValue('D1', '2008-12-31'); + +$objPHPExcel->getActiveSheet() + +->getStyle('D1') + +->getNumberFormat() + +->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_YYYYMMDDSLASH) + +// PHP-time (Unix time) + +$time = gmmktime(0,0,0,12,31,2008); // int(1230681600) + +$objPHPExcel->getActiveSheet() + +->setCellValue('D1', PHPExcel_Shared_Date::PHPToExcel($time)); + +$objPHPExcel->getActiveSheet() + +->getStyle('D1') + +->getNumberFormat() + +->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_YYYYMMDDSLASH) + +// Excel-date/time + +$objPHPExcel->getActiveSheet() + +->setCellValue('D1', 39813) + +$objPHPExcel->getActiveSheet() + +->getStyle('D1') + +->getNumberFormat() + +->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_YYYYMMDDSLASH) + +The above methods for entering a date all yield the same result. PHPExcel_Style_NumberFormat provides a lot of pre-defined date formats. + +The PHPExcel_Shared_Date::PHPToExcel() method will also work with a PHP DateTime object. + +Similarly, times (or date and time values) can be entered in the same fashion: just remember to use an appropriate format code. + +__Notes:__ + +See section "Using value binders to facilitate data entry" to learn more about the AdvancedValueBinder used in the first example. +In previous versions of PHPExcel up to and including 1.6.6, when a cell had a date-like number format code, it was possible to enter a date directly using an integer PHP-time without converting to Excel date format. Starting with PHPExcel 1.6.7 this is no longer supported. +Excel can also operate in a 1904-based calendar (default for workbooks saved on Mac). Normally, you do not have to worry about this when using PHPExcel.### Write a formula into a cell + +Inside the Excel file, formulas are always stored as they would appear in an English version of Microsoft Office Excel, and PHPExcel handles all formulae internally in this format. This means that the following rules hold: + +Decimal separator is '.' (period)Function argument separator is ',' (comma)Matrix row separator is ';' (semicolon)English function names must be usedThis is regardless of which language version of Microsoft Office Excel may have been used to create the Excel file. + +When the final workbook is opened by the user, Microsoft Office Excel will take care of displaying the formula according the applications language. Translation is taken care of by the application! + +The following line of code writes the formula “=IF(C4>500,"profit","loss")” into the cell B8. Note that the formula must start with “=” to make PHPExcel recognise this as a formula. + +$objPHPExcel->getActiveSheet()->setCellValue('B8','=IF(C4>500,"profit","loss")'); + +If you want to write a string beginning with an “=” to a cell, then you should use the setCellValueExplicit() method. + +$objPHPExcel->getActiveSheet() + +->setCellValueExplicit('B8', + +'=IF(C4>500,"profit","loss")', + +PHPExcel_Cell_DataType::TYPE_STRING + +); + +A cell’s formula can be read again using the following line of code: + +$formula = $objPHPExcel->getActiveSheet()->getCell('B8')->getValue(); + +If you need the calculated value of a cell, use the following code. This is further explained in REF _Ref191885372 \w \h \* MERGEFORMAT 4.4.35. + +$value = $objPHPExcel->getActiveSheet()->getCell('B8')->getCalculatedValue(); + +### Locale Settings for Formulae + +Some localisation elements have been included in PHPExcel.

Luckily, there is an easier way. Let Microsoft Office Excel do the work for you.For example, create in Microsoft Office Excel an xlsx file where you insert the header and footer as desired using the programs own interface. Save file as test.xlsx. Now, take that file and read off the values using PHPExcel as follows:$objPHPexcel = PHPExcel_IOFactory::load('test.xlsx');$objWorksheet = $objPHPexcel->getActiveSheet();var_dump($objWorksheet->getHeaderFooter()->getOddFooter());var_dump($objWorksheet->getHeaderFooter()->getEvenFooter());var_dump($objWorksheet->getHeaderFooter()->getOddHeader());var_dump($objWorksheet->getHeaderFooter()->getEvenHeader());That reveals the codes for the even/odd header and footer. Experienced users may find it easier to rename test.xlsx to test.zip, unzip it, and inspect directly the contents of the relevant xl/worksheets/sheetX.xml to find the codes for header/footer.### Setting printing breaks on a row or column + +To set a print break, use the following code, which sets a row break on row 10. + +$objPHPExcel->getActiveSheet()->setBreak( 'A10' , PHPExcel_Worksheet::BREAK_ROW ); + +The following line of code sets a print break on column D: + +$objPHPExcel->getActiveSheet()->setBreak( 'D10' , PHPExcel_Worksheet::BREAK_COLUMN ); + +### Show/hide gridlines when printing + +To show/hide gridlines when printing, use the following code: + +$objPHPExcel->getActiveSheet()->setShowGridlines(true); + +### Setting rows/columns to repeat at top/left + +PHPExcel can repeat specific rows/cells at top/left of a page. The following code is an example of how to repeat row 1 to 5 on each printed page of a specific worksheet: + +$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5); + +### Specify printing area + +To specify a worksheet’s printing area, use the following code: + +$objPHPExcel->getActiveSheet()->getPageSetup()->setPrintArea('A1:E5'); + +There can also be multiple printing areas in a single worksheet: + +$objPHPExcel->getActiveSheet()->getPageSetup()->setPrintArea('A1:E5,G4:M20'); + +### Formatting cells + +A cell can be formatted with font, border, fill, … style information. For example, one can set the foreground colour of a cell to red, aligned to the right, and the border to black and thick border style. Let’s do that on cell B2: + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_RED); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THICK); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THICK); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THICK); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THICK); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->getFill()->getStartColor()->setARGB('FFFF0000'); + +Starting with PHPExcel 1.7.0 getStyle() also accepts a cell range as a parameter. For example, you can set a red background color on a range of cells: + +$objPHPExcel->getActiveSheet()->getStyle('B3:B7')->getFill() + +->setFillType(PHPExcel_Style_Fill::FILL_SOLID) + +->getStartColor()->setARGB('FFFF0000'); + +__Tip__ +It is recommended to style many cells at once, using e.g. getStyle('A1:M500'), rather than styling the cells individually in a loop. This is much faster compared to looping through cells and styling them individually. + +There is also an alternative manner to set styles. The following code sets a cell’s style to font bold, alignment right, top border thin and a gradient fill: + +$styleArray = array( + +'font' => array( + +'bold' => true, + +), + +'alignment' => array( + +'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_RIGHT, + +), + +'borders' => array( + +'top' => array( + +'style' => PHPExcel_Style_Border::BORDER_THIN, + +), + +), + +'fill' => array( + +'type' => PHPExcel_Style_Fill::FILL_GRADIENT_LINEAR, + +'rotation' => 90, + +'startcolor' => array( + +'argb' => 'FFA0A0A0', + +), + +'endcolor' => array( + +'argb' => 'FFFFFFFF', + +), + +), + +); + +$objPHPExcel->getActiveSheet()->getStyle('A3')->applyFromArray($styleArray); + +Or with a range of cells: + +$objPHPExcel->getActiveSheet()->getStyle('B3:B7')->applyFromArray($styleArray); + +This alternative method using arrays should be faster in terms of execution whenever you are setting more than one style property. But the difference may barely be measurable unless you have many different styles in your workbook. + +Prior to PHPExcel 1.7.0 duplicateStyleArray() was the recommended method for styling a cell range, but this method has now been deprecated since getStyle() has started to accept a cell range. + +### Number formats + +You often want to format numbers in Excel. For example you may want a thousands separator plus a fixed number of decimals after the decimal separator. Or perhaps you want some numbers to be zero-padded. + +In Microsoft Office Excel you may be familiar with selecting a number format from the "Format Cells" dialog. Here there are some predefined number formats available including some for dates. The dialog is designed in a way so you don't have to interact with the underlying raw number format code unless you need a custom number format. + +In PHPExcel, you can also apply various predefined number formats. Example: + +$objPHPExcel->getActiveSheet()->getStyle('A1')->getNumberFormat() + +->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_NUMBER_COMMA_SEPARATED1); + +This will format a number e.g. 1587.2 so it shows up as 1,587.20 when you open the workbook in MS Office Excel. (Depending on settings for decimal and thousands separators in Microsoft Office Excel it may show up as 1.587,20) + +You can achieve exactly the same as the above by using this: + +$objPHPExcel->getActiveSheet()->getStyle('A1')->getNumberFormat() + +->setFormatCode('#,##0.00'); + +In Microsoft Office Excel, as well as in PHPExcel, you will have to interact with raw number format codes whenever you need some special custom number format. Example: + +$objPHPExcel->getActiveSheet()->getStyle('A1')->getNumberFormat() + +->setFormatCode('[Blue][>=3000]$#,##0;[Red][<0]$#,##0;$#,##0'); + +Another example is when you want numbers zero-padded with leading zeros to a fixed length: + +$objPHPExcel->getActiveSheet()->getCell('A1')->setValue(19); + +$objPHPExcel->getActiveSheet()->getStyle('A1')->getNumberFormat() + +->setFormatCode('0000'); // will show as 0019 in Excel + +__Tip__ +The rules for composing a number format code in Excel can be rather complicated. Sometimes you know how to create some number format in Microsoft Office Excel, but don't know what the underlying number format code looks like. How do you find it? + +The readers shipped with PHPExcel come to the rescue. Load your template workbook using e.g. Excel2007 reader to reveal the number format code. Example how read a number format code for cell A1: + +$objReader = PHPExcel_IOFactory::createReader('Excel2007'); +$objPHPExcel = $objReader->load('template.xlsx'); +var_dump($objPHPExcel->getActiveSheet()->getStyle('A1')->getNumberFormat()->getFormatCode()); +Advanced users may find it faster to inspect the number format code directly by renaming template.xlsx to template.zip, unzipping, and looking for the relevant piece of XML code holding the number format code in *xl/styles.xml*.### Alignment and wrap text + +Let’s set vertical alignment to the top for cells A1:D4 + +$objPHPExcel->getActiveSheet()->getStyle('A1:D4') + +->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_TOP); + +Here is how to achieve wrap text: + +$objPHPExcel->getActiveSheet()->getStyle('A1:D4') + +->getAlignment()->setWrapText(true); + +### Setting the default style of a workbook + +It is possible to set the default style of a workbook. Let’s set the default font to Arial size 8: + +$objPHPExcel->getDefaultStyle()->getFont()->setName('Arial'); +$objPHPExcel->getDefaultStyle()->getFont()->setSize(8); + +### Styling cell borders + +In PHPExcel it is easy to apply various borders on a rectangular selection. Here is how to apply a thick red border outline around cells B2:G8. + +$styleArray = array( + +'borders' => array( + +'outline' => array( + +'style' => PHPExcel_Style_Border::BORDER_THICK, + +'color' => array('argb' => 'FFFF0000'), + +), + +), + +); + +$objWorksheet->getStyle('B2:G8')->applyFromArray($styleArray); + +In Microsoft Office Excel, the above operation would correspond to selecting the cells B2:G8, launching the style dialog, choosing a thick red border, and clicking on the "Outline" border component. + +Note that the border outline is applied to the rectangular selection B2:G8 as a whole, not on each cell individually. + +You can achieve any border effect by using just the 5 basic borders and operating on a single cell at a time: + +__Array key__ + +__Maps to property__ + +left + +right + +top + +bottom + +diagonal + +getLeft() +getRight() +getTop() +getBottom() +getDiagonal() + +Additional shortcut borders come in handy like in the example above. These are the shortcut borders available: + +__Array key__ + +__Maps to property__ + +allborders +outline + +inside +vertical + +horizontal + +getAllBorders() + +getOutline() + +getInside() + +getVertical() + +getHorizontal() + +An overview of all border shortcuts can be seen in the following image: + + + +If you simultaneously set e.g. allborders and vertical, then we have "overlapping" borders, and one of the components has to win over the other where there is border overlap. In PHPExcel, from weakest to strongest borders, the list is as follows: allborders, outline/inside, vertical/horizontal, left/right/top/bottom/diagonal. + +This border hierarchy can be utilized to achieve various effects in an easy manner. + +### Conditional formatting a cell + +A cell can be formatted conditionally, based on a specific rule. For example, one can set the foreground colour of a cell to red if its value is below zero, and to green if its value is zero or more. + +One can set a conditional style ruleset to a cell using the following code: + +$objConditional1 = new PHPExcel_Style_Conditional(); + +$objConditional1->setConditionType(PHPExcel_Style_Conditional::CONDITION_CELLIS); + +$objConditional1->setOperatorType(PHPExcel_Style_Conditional::OPERATOR_LESSTHAN); + +$objConditional1->addCondition('0'); + +$objConditional1->getStyle()->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_RED); + +$objConditional1->getStyle()->getFont()->setBold(true); + +$objConditional2 = new PHPExcel_Style_Conditional(); + +$objConditional2->setConditionType(PHPExcel_Style_Conditional::CONDITION_CELLIS); + +$objConditional2->setOperatorType(PHPExcel_Style_Conditional::OPERATOR_GREATERTHANOREQUAL); + +$objConditional2->addCondition('0'); + +$objConditional2->getStyle()->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_GREEN); + +$objConditional2->getStyle()->getFont()->setBold(true); + +$conditionalStyles = $objPHPExcel->getActiveSheet()->getStyle('B2')->getConditionalStyles(); + +array_push($conditionalStyles, $objConditional1); + +array_push($conditionalStyles, $objConditional2); + +$objPHPExcel->getActiveSheet()->getStyle('B2')->setConditionalStyles($conditionalStyles); + +If you want to copy the ruleset to other cells, you can duplicate the style object: + +$objPHPExcel->getActiveSheet()->duplicateStyle( $objPHPExcel->getActiveSheet()->getStyle('B2'), 'B3:B7' ); + +### Add a comment to a cell + +To add a comment to a cell, use the following code. The example below adds a comment to cell E11: + +$objPHPExcel->getActiveSheet()->getComment('E11')->setAuthor('PHPExcel'); + +$objCommentRichText = $objPHPExcel->getActiveSheet()->getComment('E11')->getText()->createTextRun('PHPExcel:'); + + +$objCommentRichText->getFont()->setBold(true); + + +$objPHPExcel->getActiveSheet()->getComment('E11')->getText()->createTextRun("\r\n"); + + +$objPHPExcel->getActiveSheet()->getComment('E11')->getText()->createTextRun('Total amount on the current invoice, excluding VAT.'); + + + +### Apply autofilter to a range of cells + +To apply an autofilter to a range of cells, use the following code: + +$objPHPExcel->getActiveSheet()->setAutoFilter('A1:C9'); + +__Make sure that you always include the complete filter range!__ +Excel does support setting only the captionrow, but that's __not__ a best practice... + +### Setting security on a spreadsheet + +Excel offers 3 levels of “protection”: document security, sheet security and cell security. + +Document security allows you to set a password on a complete spreadsheet, allowing changes to be made only when that password is entered.Worksheet security offers other security options: you can disallow inserting rows on a specific sheet, disallow sorting, …Cell security offers the option to lock/unlock a cell as well as show/hide the internal formulaAn example on setting document security: + +$objPHPExcel->getSecurity()->setLockWindows(true); + +$objPHPExcel->getSecurity()->setLockStructure(true); + +$objPHPExcel->getSecurity()->setWorkbookPassword("PHPExcel"); + +An example on setting worksheet security: + +$objPHPExcel->getActiveSheet()->getProtection()->setPassword('PHPExcel'); + +$objPHPExcel->getActiveSheet()->getProtection()->setSheet(true); + +$objPHPExcel->getActiveSheet()->getProtection()->setSort(true); + +$objPHPExcel->getActiveSheet()->getProtection()->setInsertRows(true); + +$objPHPExcel->getActiveSheet()->getProtection()->setFormatCells(true); + +An example on setting cell security: + +$objPHPExcel->getActiveSheet()->getStyle('B1')->getProtection()->setLocked( + +PHPExcel_Style_Protection::PROTECTION_UNPROTECTED + +); + +__Make sure you enable worksheet protection if you need any of the worksheet protection features!__ This can be done using the following code: $objPHPExcel->getActiveSheet()->getProtection()->setSheet(true); + +### Setting data validation on a cell + +Data validation is a powerful feature of Excel2007. It allows to specify an input filter on the data that can be inserted in a specific cell. This filter can be a range (i.e. value must be between 0 and 10), a list (i.e. value must be picked from a list), … + +The following piece of code only allows numbers between 10 and 20 to be entered in cell B3: + +$objValidation = $objPHPExcel->getActiveSheet()->getCell('B3') + +->getDataValidation(); + +$objValidation->setType( PHPExcel_Cell_DataValidation::TYPE_WHOLE ); + +$objValidation->setErrorStyle( PHPExcel_Cell_DataValidation::STYLE_STOP ); + +$objValidation->setAllowBlank(true); + +$objValidation->setShowInputMessage(true); + +$objValidation->setShowErrorMessage(true); + +$objValidation->setErrorTitle('Input error'); + +$objValidation->setError('Number is not allowed!'); + +$objValidation->setPromptTitle('Allowed input'); + +$objValidation->setPrompt('Only numbers between 10 and 20 are allowed.'); + +$objValidation->setFormula1(10); + +$objValidation->setFormula2(20); + +The following piece of code only allows an item picked from a list of data to be entered in cell B3: + +$objValidation = $objPHPExcel->getActiveSheet()->getCell('B5') + +->getDataValidation(); + +$objValidation->setType( PHPExcel_Cell_DataValidation::TYPE_LIST ); + +$objValidation->setErrorStyle( PHPExcel_Cell_DataValidation::STYLE_INFORMATION ); + +$objValidation->setAllowBlank(false); + +$objValidation->setShowInputMessage(true); + +$objValidation->setShowErrorMessage(true); + +$objValidation->setShowDropDown(true); + +$objValidation->setErrorTitle('Input error'); + +$objValidation->setError('Value is not in list.'); + +$objValidation->setPromptTitle('Pick from list'); + +$objValidation->setPrompt('Please pick a value from the drop-down list.'); + +$objValidation->setFormula1('"Item A,Item B,Item C"'); + +When using a data validation list like above, make sure you put the list between " and " and that you split the items with a comma (,). + +It is important to remember that any string participating in an Excel formula is allowed to be maximum 255 characters (not bytes). This sets a limit on how many items you can have in the string "Item A,Item B,Item C". Therefore it is normally a better idea to type the item values directly in some cell range, say A1:A3, and instead use, say, $objValidation->setFormula1('Sheet!$A$1:$A$3');. Another benefit is that the item values themselves can contain the comma ‘,’ character itself. + +If you need data validation on multiple cells, one can clone the ruleset: + +$objPHPExcel->getActiveSheet()->getCell('B8')->setDataValidation(clone $objValidation); + +### Setting a column’s width + +A column’s width can be set using the following code: + +$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(12); + +If you want PHPExcel to perform an automatic width calculation, use the following code. PHPExcel will approximate the column with to the width of the widest column value. + +$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true); + +The measure for column width in PHPExcel does __not__ correspond exactly to the measure you may be used to in Microsoft Office Excel. Column widths are difficult to deal with in Excel, and there are several measures for the column width.1) __Inner width in character units__ (e.g. 8.43 this is probably what you are familiar with in Excel)2) __Full width in pixels__ (e.g. 64 pixels)3) __Full width in character units__ (e.g. 9.140625, value -1 indicates unset width)__PHPExcel always operates with 3) "Full width in character units"__ which is in fact the only value that is stored in any Excel file, hence the most reliable measure. Unfortunately, __Microsoft ____Office ____Excel does not present you with this ____measure__. Instead measures 1) and 2) are computed by the application when the file is opened and these values are presented in various dialogues and tool tips.The character width unit is the width of a '0' (zero) glyph in the workbooks default font. Therefore column widths measured in character units in two different workbooks can only be compared if they have the same default workbook font.If you have some Excel file and need to know the column widths in measure 3), you can read the Excel file with PHPExcel and echo the retrieved values.### Show/hide a column + +To set a worksheet’s column visibility, you can use the following code. The first line explicitly shows the column C, the second line hides column D. + +$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setVisible(true); + +$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setVisible(false); + +### Group/outline a column + +To group/outline a column, you can use the following code: + +$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setOutlineLevel(1); + +You can also collapse the column. Note that you should also set the column invisible, otherwise the collapse will not be visible in Excel 2007. + +$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setCollapsed(true); + +$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setVisible(false); + +Please refer to the part “group/outline a row” for a complete example on collapsing. + +You can instruct PHPExcel to add a summary to the right (default), or to the left. The following code adds the summary to the left: + +$objPHPExcel->getActiveSheet()->setShowSummaryRight(false); + +### Setting a row’s height + +A row’s height can be set using the following code: + +$objPHPExcel->getActiveSheet()->getRowDimension('10')->setRowHeight(100); + +### Show/hide a row + +To set a worksheet’s row visibility, you can use the following code. The following example hides row number 10. + +$objPHPExcel->getActiveSheet()->getRowDimension('10')->setVisible(false); + +Note that if you apply active filters using an AutoFilter, then this will override any rows that you hide or unhide manually within that AutoFilter range if you save the file. + +### Group/outline a row + +To group/outline a row, you can use the following code: + +$objPHPExcel->getActiveSheet()->getRowDimension('5')->setOutlineLevel(1); + +You can also collapse the row. Note that you should also set the row invisible, otherwise the collapse will not be visible in Excel 2007. + +$objPHPExcel->getActiveSheet()->getRowDimension('5')->setCollapsed(true); + +$objPHPExcel->getActiveSheet()->getRowDimension('5')->setVisible(false); + +Here’s an example which collapses rows 50 to 80: + +for ($i = 51; $i <= 80; $i++) { + +$objPHPExcel->getActiveSheet()->setCellValue('A' . $i, "FName $i"); + +$objPHPExcel->getActiveSheet()->setCellValue('B' . $i, "LName $i"); + +$objPHPExcel->getActiveSheet()->setCellValue('C' . $i, "PhoneNo $i"); + +$objPHPExcel->getActiveSheet()->setCellValue('D' . $i, "FaxNo $i"); + +$objPHPExcel->getActiveSheet()->setCellValue('E' . $i, true); + +$objPHPExcel->getActiveSheet()->getRowDimension($i)->setOutlineLevel(1); + +$objPHPExcel->getActiveSheet()->getRowDimension($i)->setVisible(false); + +} + +$objPHPExcel->getActiveSheet()->getRowDimension(81)->setCollapsed(true); + +You can instruct PHPExcel to add a summary below the collapsible rows (default), or above. The following code adds the summary above: + +$objPHPExcel->getActiveSheet()->setShowSummaryBelow(false); + +### Merge/unmerge cells + +If you have a big piece of data you want to display in a worksheet, you can merge two or more cells together, to become one cell. This can be done using the following code: + +$objPHPExcel->getActiveSheet()->mergeCells('A18:E22'); + +Removing a merge can be done using the unmergeCells method: + +$objPHPExcel->getActiveSheet()->unmergeCells('A18:E22'); + +### Inserting rows/columns + +You can insert/remove rows/columns at a specific position. The following code inserts 2 new rows, right before row 7: + +$objPHPExcel->getActiveSheet()->insertNewRowBefore(7, 2); + +### Add a drawing to a worksheet + +A drawing is always represented as a separate object, which can be added to a worksheet. Therefore, you must first instantiate a new PHPExcel_Worksheet_Drawing, and assign its properties a meaningful value: + +$objDrawing = new PHPExcel_Worksheet_Drawing(); + +$objDrawing->setName('Logo'); + +$objDrawing->setDescription('Logo'); + +$objDrawing->setPath('./images/officelogo.jpg'); + +$objDrawing->setHeight(36); + +To add the above drawing to the worksheet, use the following snippet of code. PHPExcel creates the link between the drawing and the worksheet: + +$objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); + +You can set numerous properties on a drawing, here are some examples: + +$objDrawing->setName('Paid'); + +$objDrawing->setDescription('Paid'); + +$objDrawing->setPath('./images/paid.png'); + +$objDrawing->setCoordinates('B15'); + +$objDrawing->setOffsetX(110); + +$objDrawing->setRotation(25); + +$objDrawing->getShadow()->setVisible(true); + +$objDrawing->getShadow()->setDirection(45); + +You can also add images created using GD functions without needing to save them to disk first as In-Memory drawings. + +// Use GD to create an in-memory image + +$gdImage = @imagecreatetruecolor(120, 20) or die('Cannot Initialize new GD image stream'); + +$textColor = imagecolorallocate($gdImage, 255, 255, 255); + +imagestring($gdImage, 1, 5, 5, 'Created with PHPExcel', $textColor); + +// Add the In-Memory image to a worksheet + +$objDrawing = new PHPExcel_Worksheet_MemoryDrawing(); + +$objDrawing->setName('In-Memory image 1'); + +$objDrawing->setDescription('In-Memory image 1'); + +$objDrawing->setCoordinates('A1'); + +$objDrawing->setImageResource($gdImage); + +$objDrawing->setRenderingFunction( + +PHPExcel_Worksheet_MemoryDrawing::RENDERING_JPEG + +); + +$objDrawing->setMimeType(PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_DEFAULT); + +$objDrawing->setHeight(36); + +$objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); + +### Reading Images from a worksheet + +A commonly asked question is how to retrieve the images from a workbook that has been loaded, and save them as individual image files to disk. + +The following code extracts images from the current active worksheet, and writes each as a separate file. + +$i = 0; + +foreach ($objPHPExcel->getActiveSheet()->getDrawingCollection() as $drawing) { + +if ($drawing instanceof PHPExcel_Worksheet_MemoryDrawing) { + +ob_start(); + +call_user_func( + +$drawing->getRenderingFunction(), + +$drawing->getImageResource() + +); + +$imageContents = ob_get_contents(); + +ob_end_clean(); + +switch ($drawing->getMimeType()) { + +case PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_PNG : + +$extension = 'png'; break; + +case PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_GIF: + +$extension = 'gif'; break; + +case PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_JPEG : + +$extension = 'jpg'; break; + +} + +} else { + +$zipReader = fopen($drawing->getPath(),'r'); + +$imageContents = ''; + +while (!feof($zipReader)) { + +$imageContents .= fread($zipReader,1024); + +} + +fclose($zipReader); + +$extension = $drawing->getExtension(); + +} + +$myFileName = '00_Image_'.++$i.'.'.$extension; + +file_put_contents($myFileName,$imageContents); + +} + +### Add rich text to a cell + +Adding rich text to a cell can be done using PHPExcel_RichText instances. Here’s an example, which creates the following rich text string: + +This invoice is *__payable within thirty days after the end of the month__* unless specified otherwise on the invoice. + +$objRichText = new PHPExcel_RichText(); + +$objRichText->createText('This invoice is '); + +$objPayable = $objRichText->createTextRun('payable within thirty days after the end of the month'); + +$objPayable->getFont()->setBold(true); + +$objPayable->getFont()->setItalic(true); + +$objPayable->getFont()->setColor( new PHPExcel_Style_Color( PHPExcel_Style_Color::COLOR_DARKGREEN ) ); + +$objRichText->createText(', unless specified otherwise on the invoice.'); + +$objPHPExcel->getActiveSheet()->getCell('A18')->setValue($objRichText); + +### Define a named range + +PHPExcel supports the definition of named ranges. These can be defined using the following code: + +// Add some data + +$objPHPExcel->setActiveSheetIndex(0); + +$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Firstname:'); + +$objPHPExcel->getActiveSheet()->setCellValue('A2', 'Lastname:'); + +$objPHPExcel->getActiveSheet()->setCellValue('B1', 'Maarten'); + +$objPHPExcel->getActiveSheet()->setCellValue('B2', 'Balliauw'); + +// Define named ranges + +$objPHPExcel->addNamedRange( new PHPExcel_NamedRange('PersonFN', $objPHPExcel->getActiveSheet(), 'B1') ); + +$objPHPExcel->addNamedRange( new PHPExcel_NamedRange('PersonLN', $objPHPExcel->getActiveSheet(), 'B2') ); + +Optionally, a fourth parameter can be passed defining the named range local (i.e. only usable on the current worksheet). Named ranges are global by default. + +### Redirect output to a client’s web browser + +Sometimes, one really wants to output a file to a client’s browser, especially when creating spreadsheets on-the-fly. There are some easy steps that can be followed to do this: + +Create your PHPExcel spreadsheetOutput HTTP headers for the type of document you wish to outputUse the PHPExcel_Writer_* of your choice, and save to “php://output”PHPExcel_Writer_Excel2007 uses temporary storage when writing to php://output. By default, temporary files are stored in the script’s working directory. When there is no access, it falls back to the operating system’s temporary files location. + +__This may not be safe for unauthorized viewing!__ +Depending on the configuration of your operating system, temporary storage can be read by anyone using the same temporary storage folder. When confidentiality of your document is needed, it is recommended not to use php://output. + +#### HTTP headers + +Example of a script redirecting an Excel 2007 file to the client's browser: + +save('php://output'); + +?> + +Example of a script redirecting an Excel5 file to the client's browser: + +save('php://output'); + +?> + +Caution: + +Make sure not to include any echo statements or output any other contents than the Excel file. There should be no whitespace before the opening tag (which can also be omitted to avoid problems).Make sure that your script is saved without a BOM (Byte-order mark). (Because this counts as echoing output)Same things apply to all included filesFailing to follow the above guidelines may result in corrupt Excel files arriving at the client browser, and/or that headers cannot be set by PHP (resulting in warning messages). + +### Setting the default column width + +Default column width can be set using the following code: + +$objPHPExcel->getActiveSheet()->getDefaultColumnDimension()->setWidth(12); + +### Setting the default row height + +Default row height can be set using the following code: + +$objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(15); + +### Add a GD drawing to a worksheet + +There might be a situation where you want to generate an in-memory image using GD and add it to a PHPExcel worksheet without first having to save this file to a temporary location. + +Here’s an example which generates an image in memory and adds it to the active worksheet: + +// Generate an image + +$gdImage = @imagecreatetruecolor(120, 20) or die('Cannot Initialize new GD image stream'); + +$textColor = imagecolorallocate($gdImage, 255, 255, 255); + +imagestring($gdImage, 1, 5, 5, 'Created with PHPExcel', $textColor); + +// Add a drawing to the worksheet + +$objDrawing = new PHPExcel_Worksheet_MemoryDrawing(); + +$objDrawing->setName('Sample image'); + +$objDrawing->setDescription('Sample image'); + +$objDrawing->setImageResource($gdImage); + +$objDrawing->setRenderingFunction(PHPExcel_Worksheet_MemoryDrawing::RENDERING_JPEG); + +$objDrawing->setMimeType(PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_DEFAULT); + +$objDrawing->setHeight(36); + +$objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); + +### Setting worksheet zoom level + +To set a worksheet’s zoom level, the following code can be used: + +$objPHPExcel->getActiveSheet()->getSheetView()->setZoomScale(75); + +Note that zoom level should be in range 10 – 400. + +### Sheet tab color + +Sometimes you want to set a color for sheet tab. For example you can have a red sheet tab: + +$objWorksheet->getTabColor()->setRGB('FF0000'); + +### Creating worksheets in a workbook + +If you need to create more worksheets in the workbook, here is how: + +$objWorksheet1 = $objPHPExcel->createSheet(); + +$objWorksheet1->setTitle('Another sheet'); + +Think of createSheet() as the "Insert sheet" button in Excel. When you hit that button a new sheet is appended to the existing collection of worksheets in the workbook.### Hidden worksheets (Sheet states) + +Set a worksheet to be __hidden__ using this code: + +$objPHPExcel->getActiveSheet() + +->setSheetState(PHPExcel_Worksheet::SHEETSTATE_HIDDEN); + +Sometimes you may even want the worksheet to be __“very hidden”__. The available sheet states are : + +PHPExcel_Worksheet::SHEETSTATE_VISIBLE + +PHPExcel_Worksheet::SHEETSTATE_HIDDEN + +PHPExcel_Worksheet::SHEETSTATE_VERYHIDDEN + +In Excel the sheet state “very hidden” can only be set programmatically, e.g. with Visual Basic Macro. It is not possible to make such a sheet visible via the user interface.### Right-to-left worksheet + +Worksheets can be set individually whether column ‘A’ should start at left or right side. Default is left. Here is how to set columns from right-to-left. + +// right-to-left worksheet + +$objPHPExcel->getActiveSheet() + +->setRightToLeft(true); + +# Performing formula calculations + +## Using the PHPExcel calculation engine + +As PHPExcel represents an in-memory spreadsheet, it also offers formula calculation capabilities. A cell can be of a value type (containing a number or text), or a formula type (containing a formula which can be evaluated). For example, the formula "=SUM(A1:A10)" evaluates to the sum of values in A1, A2, ..., A10. + +To calculate a formula, you can call the cell containing the formula’s method getCalculatedValue(), for example: + +$objPHPExcel->getActiveSheet()->getCell('E11')->getCalculatedValue(); + +If you write the following line of code in the invoice demo included with PHPExcel, it evaluates to the value "64": + + + +Another nice feature of PHPExcel's formula parser, is that it can automatically adjust a formula when inserting/removing rows/columns. Here's an example: + + + +You see that the formula contained in cell E11 is "SUM(E4:E9)". Now, when I write the following line of code, two new product lines are added: + +$objPHPExcel->getActiveSheet()->insertNewRowBefore(7, 2); + + + +Did you notice? The formula in the former cell E11 (now E13, as I inserted 2 new rows), changed to "SUM(E4:E11)". Also, the inserted cells duplicate style information of the previous cell, just like Excel's behaviour. Note that you can both insert rows and columns. + +## Known limitations + +There are some known limitations to the PHPExcel calculation engine. Most of them are due to the fact that an Excel formula is converted into PHP code before being executed. This means that Excel formula calculation is subject to PHP’s language characteristics. + +### Operator precedence + +In Excel '+' wins over '&', just like '*' wins over '+' in ordinary algebra. The former rule is not what one finds using the calculation engine shipped with PHPExcel. + +Reference for operator precedence in Excel: + +Reference for operator precedence in PHP: + +### Formulas involving numbers and text + +Formulas involving numbers and text may produce unexpected results or even unreadable file contents. For example, the formula '=3+"Hello "' is expected to produce an error in Excel (#VALUE!). Due to the fact that PHP converts “Hello” to a numeric value (zero), the result of this formula is evaluated as 3 instead of evaluating as an error. This also causes the Excel document being generated as containing unreadable content. + +Reference for this behaviour in PHP: + +[http://be.php.net/manual/en/language.types.string.php#language.types.string.conversion][20] + +# Reading and writing to file + +As you already know from part REF _Ref191885438 \w \h 3.3 REF _Ref191885438 \h Readers and writers, reading and writing to a persisted storage is not possible using the base PHPExcel classes. For this purpose, PHPExcel provides readers and writers, which are implementations of PHPExcel_Writer_IReader and PHPExcel_Writer_IWriter. + +## PHPExcel_IOFactory + +The PHPExcel API offers multiple methods to create a PHPExcel_Writer_IReader or PHPExcel_Writer_IWriter instance: + +Direct creationVia PHPExcel_IOFactoryAll examples underneath demonstrate the direct creation method. Note that you can also use the PHPExcel_IOFactory class to do this. + +### Creating PHPExcel_Reader_IReader using PHPExcel_IOFactory + +There are 2 methods for reading in a file into PHPExcel: using automatic file type resolving or explicitly. + +Automatic file type resolving checks the different PHPExcel_Reader_IReader distributed with PHPExcel.

For example, one might want to see instead of . + +You can use the following code to achieve this result: + +$objWriter->setImagesRoot('http://www.example.com'); + +#### Formula pre-calculation + +By default, this writer pre-calculates all formulas in the spreadsheet. This can be slow on large spreadsheets, and maybe even unwanted. You can however disable formula pre-calculation: + +$objWriter = new PHPExcel_Writer_HTML($objPHPExcel); +$objWriter->setPreCalculateFormulas(false); + +$objWriter->save("05featuredemo.htm"); + +#### Embedding generated HTML in a web page + +There might be a situation where you want to embed the generated HTML in an existing website. PHPExcel_Writer_HTML provides support to generate only specific parts of the HTML code, which allows you to use these parts in your website. + +Supported methods: + +generateHTMLHeader()generateStyles()generateSheetData()generateHTMLFooter()Here’s an example which retrieves all parts independently and merges them into a resulting HTML page: + +generateHTMLHeader(); +?> + + +?> + +--> + + + +generateSheetData(); +echo $objWriter->generateHTMLFooter(); +?> + +#### Writing UTF-8 HTML files + +A HTML file can be marked as UTF-8 by writing a BOM file header. This can be enabled by using the following code: + +$objWriter = new PHPExcel_Writer_HTML($objPHPExcel); +$objWriter->setUseBOM(true); + +$objWriter->save("05featuredemo.htm"); + +#### Decimal and thousands separators + +See section PHPExcel_Writer_CSV how to control the appearance of these. + +## PDF + +PHPExcel allows you to write a spreadsheet into PDF format, for fast distribution of represented data. + +__PDF limitations__ +Please note that PDF file format has some limits regarding to styling cells, number formatting, … + +### PHPExcel_Writer_PDF + +PHPExcel’s PDF Writer is a wrapper for a 3rd-Party PDF Rendering library such as tcPDF, mPDF or DomPDF. Prior to version 1.7.8 of PHPExcel, the tcPDF library was bundled with PHPExcel; but from version 1.7.8 this was removed. Instead, you must now install a PDF Rendering library yourself; but PHPExcel will work with a number of different libraries. + +Currently, the following libraries are supported: + +__Library__ + +__Version used for testing__ + +__Downloadable from__ + +__PHPExcel Internal Constant__ + +tcPDF + +5.9 + +http://www.tcpdf.org/ + +PDF_RENDERER_TCPDF + +mPDF + +5.4 + +http://www.mpdf1.com/mpdf/ + +PDF_RENDERER_MPDF + +domPDF + +0.6.0 beta 3 + +http://code.google.com/p/dompdf/ + +PDF_RENDERER_DOMPDF + +The different libraries have different strengths and weaknesses. Some generate better formatted output than others, some are faster or use less memory than others, while some generate smaller .pdf files. It is the developers choice which one they wish to use, appropriate to their own circumstances. + +Before instantiating a Writer to generate PDF output, you will need to indicate which Rendering library you are using, and where it is located. + +$rendererName = PHPExcel_Settings::PDF_RENDERER_MPDF; + +$rendererLibrary = 'mPDF5.4'; + +$rendererLibraryPath = dirname(__FILE__).'/../../../libraries/PDF/' . $rendererLibrary; + +if (!PHPExcel_Settings::setPdfRenderer( + +$rendererName, + +$rendererLibraryPath + +)) { + +die( + +'Please set the $rendererName and $rendererLibraryPath values' . + +PHP_EOL . + +' as appropriate for your directory structure' + +); + +} + +#### Writing a spreadsheet + +Once you have identified the Renderer that you wish to use for PDF generation, you can write a .pdf file using the following code: + +$objWriter = new PHPExcel_Writer_PDF($objPHPExcel); + +$objWriter->save("05featuredemo.pdf"); + +Please note that PHPExcel_Writer_PDF only outputs the first worksheet by default. + +#### Write all worksheets + +PDF files can contain one or more worksheets.
