Note Submitter: tsa@medicine.wisc.edu ---- 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; } }
