' | |$item= = ' ... ')                    Continue; $info=$path.‘ /‘.$item; if(Is_dir($info) &&$item! = '. ' &&$item! = ' ... ') {Dealfileindir ($info); }Else{                    //print $info. ' <br/> ';@unlink($info); }            }            Closedir($DP); }        if($type)            @rmdir($path); }}
