Answer 1

 echo $_SERVER['SCRIPT_NAME']."?".$_SERVER['QUERY_STRING'];
 // or (if you have to use $from)
 $from = $_SERVER['REQUEST_URI'];
 $url = parse_url($from);
 echo $url['path']."?".$url['query'];
 //or
 $url = explode("/",$from);
 echo $url[1];

Answer 2

$temp = explode("/",$from);
$temp = end($temp);

or even easier

basename($from);
