# Configuration Settings
|
|
|
|
Once you have included the PhpSpreadsheet files in your script, but
|
|
before instantiating a `Spreadsheet` 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 collection caching
|
|
|
|
By default, PhpSpreadsheet holds all cell objects in memory, but
|
|
you can specify alternatives to reduce memory consumption at the cost of speed.
|
|
Read more about [memory saving](./memory_saving.md).
|
|
|
|
To enable cell caching, you must provide your own implementation of cache like so:
|
|
|
|
```php
|
|
$cache = new MyCustomPsr16Implementation();
|
|
|
|
\PhpOffice\PhpSpreadsheet\Settings::setCache($cache);
|
|
```
|
|
|
|
## Language/Locale
|
|
|
|
Some localisation elements have been included in PhpSpreadsheet. You can
|
|
set a locale by changing the settings. To set the locale to Brazilian
|
|
Portuguese you would use:
|
|
|
|
```php
|
|
$locale = 'pt_br';
|
|
$validLocale = \PhpOffice\PhpSpreadsheet\Settings::setLocale($locale);
|
|
if (!$validLocale) {
|
|
echo 'Unable to set locale to ' . $locale . " - reverting to en_us" . PHP_EOL;
|
|
}
|
|
```
|
|
|
|
- If Brazilian Portuguese language files aren't available, then 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 [Locale Settings for
|
|
Formulae](./recipes.md#locale-settings-for-formulae).
