You are looking for

$_SERVER["QUERY_STRING"]

You can find all (usually) predefined variables in PHP here.

What often helps is doing a phpinfo() that will list all environment and other variables that are currently set.

That is called a GET variable, and you can acces it via the global variable

$_GET['affiliate']

So in your code you would do something like:

if(isset($_GET['affiliate']))
      /*do something with the var*/

or if you are really interested in just the string itself you can access it using the

$_SERVER["QUERY_STRING"]

global variable

You can combine $_SERVER['QUERY_STRING'] with parse_url function in PHP (http://php.net/manual/en/function.parse-url.php) to get the url components.
