Package:          Documentation problem
Bug Type:         Documentation Problem
Bug description:Highlight that 3rd argument $matches only became optional in 5.4.0

Description:
------------
---
From manual page:
http://www.php.net/function.preg-match-all#refsect1-function.preg-match-all-description
---

The fact that the 3rd argument matches was not optional before 5.4.0 needs
to be highlighted at the top the documentation, not buried in the change
log.



Test script:
---------------
<?php
// PHP 5.3.2
if (preg_match_all('/a/', 'aaa') === false) error_log("returns
false");
?>


Expected result:
----------------
Nothing

Actual result:
--------------
PHP Warning:  preg_match_all() expects at least 3 parameters, 2 given in
/var/www/noname/test.php on line 3
PHP Stack trace:
PHP   1. {main}() /var/www/noname/test.php:0
PHP   2. preg_match_all() /var/www/noname/test.php:3
returns false
