note 20798 added to function.preg-match

It is possible to do negative lookbehinds with PCRE (perl 5+), but only fixed length. preg_match('/(?<!AB)C/',$foo,$match); This will match 'C' only if NOT preceeded by 'AB'. 'AB' must be a fixed length string, it cannot be an expression. -- http://www.php.net/manual/en/function.preg-match.php http://master.php.net/manage/user-notes.php?action=edit+20798 http://master.php.net/manage/user-notes.php?action=delete+20798 http://master.php.net/manage/user-notes.php?action=reject+20798
