$_GET['key2']

will get you the value from a query string.

$_POST['key2']

will get you the value from a form posted.

$_REQUEST['key2']

will get you either of the above if it exists.

var_dump( $_GET['key2'] );

var_dump displays the variable. You can always consult php manual (php.net) to know usage of a function.

var_dump is like a more informative version of echo used solely for debugging. So even if it was blank it would display something.

GET data is decoded into the $_GET super-global array. See http://php.net/manual/en/language.variables.external.php
