From:             
Operating system: 
PHP version:      5.3.6
Package:          Documentation problem
Bug Type:         Documentation Problem
Bug description:preg_match() returns zero if an error occurred

Description:
------------
---
From manual page:
http://www.php.net/manual/en/function.preg-match.php#Return Values
---

A bug was already opened (#51741) about this but not treated. If an error
occurs (like reaching pcre.backtrack_limit), preg_match doesn't return
FALSE as described in the documentation but returns 0.

It should be nice to update the documentation.
