Description:
------------
Hi,

Although the bug report at http://bugs.php.net/bug.php?id=25754 said the documentation would be fixed (back in 2004), I didn't see any mention on the preg_replace or preg_replace_callback pages of this bug.

thanks,
Brett

Reproduce code:
---------------
Try preg_replace or preg_replace_callback on a large file of code.

Expected result:
----------------
It replaces the text

Actual result:
--------------
In my case at least, the preg_replace_callback function returned nothing back.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"The maximum length of a subject string is the largest positive number that an integer variable can hold. However, PCRE uses recursion to handle subpatterns and indefinite repetition. This means that the available stack space may limit the size of a subject string that can be processed by certain patterns."
