Iterators prev() behavior is now consistent with next(), meaning
that it can go out of bounds and it must be validated with valid()
before using it.

Rowspans/colspans are now respected for each HTML document added to an existing
spreadsheet as a new worksheet. The protected $rowspan class property should
be emptied on each call to `loadIntoExisting`.

When cloning `BaseDrawing`, its worksheet will be set as null and thus be
orphaned. But when cloning the worksheet, it will re-assign itself as the
new worksheet for the BaseDrawing.
That way we avoid recursive cloning of a Worksheet that would clone a
BaseDrawing that would clone a Worksheet etc.

We now always trust the file extension to avoid false positive of mime

if the file extension does not match or is missing.

Editing a Xlsx document using PhpSpreadsheet should preserve the workbook
view attributes of that document. For example, if the worksheet tabs are
hidden in the original document, they should remain hidden after updating.

Properly set the selected cells for worksheets with frozen panes when
writing Xlsx documents. Beforehand, the saved Xlsx documents were

This change adds support for newer functions that are prefixed

Some computer programs will output xlsx files that do not compare 100%

setZoomScaleNormal() should throw exception when manually setting the

CSV reader used to accept any file without any kind of check. That made

Column indexes are always based on 1 everywhere in PhpSpreadsheet.
This is consistent with rows starting at 1, as well as Excel
function `COLUMN()`. It should also make it easier to reason about
columns and rows and remove any doubts whether a specific method is
expecting 0 based or 1 based indexes.

This allow to create and configure the standard instance of the
external PDF libary, before returning it to the standard writer.
Or, more powerful, this allow to provide a custom implementation
of the external PDF library, allowing for custom behaviors. An
example of that would something like: https://tcpdf.org/examples/example_003/Closes#266
Previously the function did not check whether the return value of `ZipArchive::locateName`
was `false`. And when it was, it was passed straight into `ZipArchive::getFromIndex`,
which casts it to an integer, resulting in it incorrectly retrieving the entry at index `0`.
Fixes#262Closes#268
We used to have some kind of wrapper that didn't do much except
forward methods to the real instance. That unnecessary complexity
made it harder to work with the real writer instance.
Temporary directory set to PDF writer is passed to mPDF object in constructor.
mPDF 7.0 changed temporary directory configuration from constant to constructor parameter.
Without this change it is not possible to change default temporary directory.

When describing a cell, the cell reference (r="A1") is optional.

When the xml file is not a standard xml file, the `simplexml_load_string` will return false, this will cause an error on "$xml->getNamespaces(true);" . So instead of showing the error, we throw an exception.
Control characters in cell values are automatically escaped without
the need to excplicitly call `StringHelper::buildCharacterSets()` beforehand.

The static variable $imageCounter previously had a constant value of 0 throughout the program as it was never being modified, because it was commented out by mistake.

Add option to suppress validation of sheet titles
Based on a "lowest common denominator" approach to compatibility,
we will continue to enforce a 31-character limit for sheet titles.
However, this limit should not be enforced when loading an existing
file.
Added a new optional parameter to Worksheet::setTitle() and
Worksheet::setCodeName() to suppress validation and massaging,
based on the premise that existing files should be given a
best-effort approach to loading and parsing. Unfortunately, it's
not possible with the current architecture to prevent users from
making use of this functionality, aside from with a strongly-worded
warning.
Added test coverage. I didn't see any existing unit tests of the
Worksheet class, so I created a new test to cover these methods.
Fixes#176
Fixes the PHP 7.1 bug reported over at PHPOffice/PHPExcel#1110
The behavior should not change since the default value used should behave the same way as the string value in earlier PHP versions.
Fixes a return type in the doc block of IReader.
Closes#165
We used to type hint against IWriter for writer part parent, but this
was not respected in writer part who often coded against the implementation
instead of the interface. With this change we make it a requirement for
writer parts to use their respective writer implementation instead of an
interface. This give legitimate access to all `BaseWriter` methods amongst
other things.
Having default values made it harder for end-user to figure out whether
it the arguement had to be supplied or not. Ommitting the argument may
lead to hard to debug issues, and is overall not a good idea.
Closes#110
In some exotic environnement (IBM AIX) it may happens that `//TRANSLIT` is not supported. In that case iconv would return false. We can easily identify the case and fallback on mbstring instead. That should give correct result.
Closes#135Closes#136
This is a hard limit of the BIFF format that cannot be worked around,
so it is best to throw exceptions than silently discard data or generate
corrupted files.
This drop a lot of non-core features code and delegate their maintainance
to third parties. Also it open the door to any missing implementation
out of the box, such as Redis for the moment.
Finally this consistently enforce a constraint where there can be one and
only one active cell at any point in time in code. This used to be true for
non-default implementation of cache, but it was not true for default
implementation where all cells were kept in-memory and thus were never
detached from their worksheet and thus were all kept functionnal at any
point in time.
This inconsistency of behavior between in-memory and off-memory could
lead to bugs when changing cache system if the end-user code was badly
written. Now end-user will never be able to write buggy code in the first
place, avoiding future headache when introducing caching.
Closes#3
We use to write the wrong property to file, leading to a warning
in PHP 7.1 since the `switch` never matched anything and the variable
was left as a string instead of as an int.
Closes https://github.com/PHPOffice/PHPExcel/issues/1110
Removed "unescape enclosure functionality", since the unescaping is already handled by fgetcsv,
and performing the unescaping again would actually result int the text from the cell being read wrong.
As an example try parsing the folowing CSV:
```
"<img alt="""" src=""http://example.com/image.jpg"" />"
```
With the additional unescaping it would have ended up as:
```
<img alt=" src="http://example.com/image.jpg" />
```
instead of the correct:
```
<img alt="" src="http://example.com/image.jpg" />
```

Those were deprecated a long time ago in 59932b0cac

Over the years PclZip became a maintenance problem. It's code base
is old and the official project seems to have died out. ZipArchive
is now more commonly available and offer an easier and more complete
API. So PclZip was dropped in order to focus our efforts on what matters.
Closes#18
We need to make note of two things:
- The old code was trying to clone an objectArray, and hence was performing a shallow copy of memoryDrawing objects (the __clone magic function was not getting invoked).
Instead, if one loops over the objectArray, and then clones the individual memory drawing objects, then the __clone function for the MemoryDrawing object is invoked.
- The __clone function for memory drawing was using the clone keyword which does not deal with circular references (Since memoryDrawing object had references to worksheet object, it was encountering an infinite loop). However, serializing and unserializing objects deals with circular references pretty well.
Fixes#92Closes#106
By design, UTF-8 allows any byte-oriented substring searching algorithm,
since the sequence of bytes for a character cannot occur anywhere else
([source](https://en.wikipedia.org/wiki/UTF-8#Advantages_3)).
So `str_replace()` also works for UTF-8-encoded strings, assuming that
the input strings are valid UTF-8 strings. The previous implementation
of mbStrReplace() did nothing to detect invalid strings.
Also, `str_replace()` does not support [Unicode equivalence](https://en.wikipedia.org/wiki/Unicode_equivalence),
but nor do the other `mb_string` functions, and nor does `=SUBSTITUTE()` in Excel
(tested on Excel for Mac version 15.19.1, Excel 2016 for Windows and LibreOffice 5.1).
