url

Example current URL http://www.domain.com/subdomain/install/finish.php

I use this code to get the current URL.

$url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];

Now I want to get the URL looks like http://www.domain.com/subdomain if there don't have sub-folder it will read like http://www.domain.com

Let me know.
