What the heck, I thought I'd throw another function in the mix. It's not pretty but the following function counts backwards from your starting point and tells you the last occurrance of a mixed char string: function strrposmixed ($haystack, $needle, $start=0) { // init start as the end of the str if not set if($start == 0) { $start = strlen($haystack); } // searches backward from $start $currentStrPos=$start; $lastFoundPos=false; while($currentStrPos != 0) { if(!(strpos($haystack,$needle,$currentStrPos) === false)) { $lastFoundPos=strpos($haystack,$needle,$currentStrPos); break; } $currentStrPos--; } if($lastFoundPos === false) { return false; } else { return $lastFoundPos; } } ---- Manual Page -- http://www.php.net/manual/en/function.strrpos.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42638 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42638&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42638&report=yes Search -- http://master.php.net/manage/user-notes.php
