you have a string with the whole URL on the variable:

$_SERVER['PHP_SELF']

then you can split string by using php functions to get different parts of string. Functions like strpos to get the position of a character inside an string, or functions like substr to get a part of the string.

Here you have the list of all string functions:
http://www.php.net/manual/en/ref.strings.php

Hope it helps.

Of course possible!
$domainArray = explode('.', $_SERVER["SERVER_NAME"]);
$variable1 = $domainArray[0];
$variable2 = $domainArray[1] . '.' . $domainArray[2];
$variable3 = $_SERVER['REQUEST_URI'];

I generally agree with Medo3777, however the URL might be something like www.atf77.whitehouse.gov/csm/index.php?q=foo.bar so you might want to learn about the PHP functions that parse strings and parse urls.  Google those terms and you will find a wealth of generalized solutions for parsing this sort of information.
