note 27422 added to pcre.pattern.syntax

Maybe it was my missunderstanding, but I could not make back reference work on my PHP 4.2.3/Win32/IIS5. Neither below used example: ((?i)rah)\s+\1 worked for me. After hours of hopeless debugging I tried to add one more backslash to back reference: ((?i)rah)\s+\\1 - at the moment it started to work:-) Hope this will help someone:-) -- http://www.php.net/manual/en/pcre.pattern.syntax.php http://master.php.net/manage/user-notes.php?action=edit+27422 http://master.php.net/manage/user-notes.php?action=delete+27422 http://master.php.net/manage/user-notes.php?action=reject+27422
