You can use like this,

$url = "http://example.com/zip.php";
$path_parts = pathinfo($url);    
echo $path_parts['extension'];

Checkout pathinfo() in the PHP core as well as parse_url(): http://php.net/parse_url. http://php.net/manual/en/function.pathinfo.php

Use it with $_SERVER['REQUEST_URI'] and the PATHINFO_EXTENSION flag. This should help. Then you can use it within a switch statement:

$url_parts = parse_url($_SERVER['REQUEST_URI']);
$extension = pathinfo($url_parts['path'], PATHINFO_EXTENSION);

switch ($extension) {
 case "mp4":
   //do something for mp4.
   break;
 case "wav":
   //do something for wav.
   break;
}

This works for if the URL has paramters on it as well. http://website.com/file.mp4?param=var would still yeild mp4. Using just pathinfo() would give you "mp4?param=var" in this case.

I've not run this code, just I expect it to work. You may also want to use strtolower() before your extension just in case its in upper case in the address bar.
