i think solution check whether '.' [dot] present after last '/'. if so, remove after last '/'. didn't logic write in php

i can't check if there exists '.html', because file name can .php, .jpg, .jsp or that

function stripfile($in){     $pieces = explode("/", $in); // split url /     if(count($pieces) < 4) return $in . "/";     if(strpos(end($pieces), ".") !== false){ // got filename @ end         array_pop($pieces); // remove filename     }elseif(end($pieces) !== ""){ // ends name without extension, i.e. directory         $pieces[] = ""; // when $pieces imploded, "/" , "" appended     }     // else, ends slash     return implode("/", $pieces); }
