note 38996 deleted from function.strpos by nlopess

Note Submitter: alexandre@dutra-cancado.net ---- Here's a (very) simple function to find the last occurence of a string in another one. I compared mine with some others which do the same job, and it seems that this one is a little bit faster because it avoids recursivity (multiple calls to strpos()). Hope this helps! <?php /* * @description: finds the last occurrence of * $needle in $haystack, * begining the search at the * $start-th character in $haystack * @returns: the start position of the * last occurence of $needle, * or false if $needle is not found */ function strlastpos($haystack, $needle, $start = 0){ $pos=strpos( strrev(substr($haystack,$start)), $needle===null?null:strrev($needle) //this is just to avoid errors when $needle = null (which is unlikely :-) ); if($pos===false) return false; else return strlen($haystack)-$pos-strlen($needle); } ?>
