Description:
------------
Bug #41788 preg_replace_callback returns NULL instead of input or error


This Report already named the circumstances. Although it is NOT A BUG,
the description in the documentation is not complete.

The return of the NULL value (and PHP Skalar-Type) is not mentioned,
only String and Array are mentioned.

Please add the NULL return case as well in the documentation. Thanks.
