Runs all the enabled filters on a piece of text.

Note: Because filters can inject JavaScript or execute PHP code, security is vital here. When a user supplies a text format, you should validate it using filter_access() before accepting/using it. This is normally done in the validation stage of the Form API. You should for example never make a preview of content in a disallowed format.


$text: The text to be filtered.

$format_id: (optional) The format ID of the text to be filtered. If no format is assigned, the fallback format will be used. Defaults to NULL.

$langcode: (optional) The language code of the text to be filtered, e.g. 'en' for English. This allows filters to be language aware so language specific text replacement can be implemented. Defaults to an empty string.

$cache: (optional) A Boolean indicating whether to cache the filtered output in the {cache_filter} table. The caller may set this to FALSE when the output is already cached elsewhere to avoid duplicate cache lookups and storage. Defaults to FALSE.

Return value

The filtered text.
