The $_GET variable is used to gather values/data from a form or url.
Information sent using the $_GET varible is visible in the users web browser, for example http://yourdomain.com/?url=http://google.com which has defined http://google.com as the url.

So for example if i was to use the following php code:

<?php

print $_GET['url'];

?>

It will display the domain http://google.com.

You can change this to anything else, you may change the url to name and then add john after = which when requesting for $_GET['name'] will display john.
