Retrieve the extension of the URL

Question

I want to hit a URL - http://www.blahblah.com/on/demand

After each hit the aforementioned URL will generate an extension.

I.e. http://www.blahblah.com/on/demand/C1212

So, that I want to do is to take the generated extension (C1212) I have no idea how can I do this? Does anyone know how can I do this with PHP?

http://www.blahblah.com/on/demand redirects to http://www.blahblah.com/on/demand/C1212 ? — theredled, Nov 08 '12 at 09:21
No, it doesn't redirect. You can see this only if you press INSPECT ELEMENT. And generally is using an IBM mechanism to make this generation — Nick Robertson, Nov 08 '12 at 09:26
@NickRobertson Could you give an example for a site that does this so we could check whether you can read it in the headers of the site? (hence be able to use cURL to find out). — h2ooooooo, Nov 08 '12 at 09:32
@NickRobertson — Is your question "How do I use PHP to get the URL from the href attribute of a link in an HTML document at a particular URL?" — Quentin, Nov 08 '12 at 09:44

Hope this answers you. Try this out.

<?php
    $url = $_SERVER['REQUEST_URI'];
    $extension = end(explode('/',$url));
    echo $extension;        
?>
