$_GET is a what's known as a superglobal. The PHP documentation states that it is an "associative array of variables passed to the current script via the URL parameters (aka. query string). Note that the array is not only populated for GET requests, but rather for all requests with a query string.". It's a means of finding out information about the current request. For a reference to $_GET["cat"] to make sense, you're probably dealing with a URL param with name of "cat". eg. http://url.com?cat=something
