[RESOLVED] Part of URL

I have urlin the followin format:

I need to take the final part and analyse. If it is in CAPS and if has 5 alpha chars in it. Something like:

ereg("^[^A-Z]*$", $_GET['whatchamacallit']) && strlen($_GET['whatchamacallit']) != 5) {
   FALSE
} else {
   TRUE
}

I just do not know hot to capture that last part after domain into a variable...

Use the path from [man]parse_url/man.

EDIT:
Or are you asking for what $GET['whatchamacallit'] should be? $SERVER['SCRIPT_NAME'] is probably what you are looking for then.

You'll need to do a mod_rewrite to redirect the URL to a php file.

Great.
