Not question just notes for other students as confused as me about $_GET

I feel like this should be clearer in the video. Alena just pulls $_GET out of thin air.

$_GET is an associative array of variables passed to the current script via the URL parameters. for example:

<?php echo 'Hello ' . htmlspecialchars($_GET["name"]) . '!'; 

If entered http://example.com/?name=Hannes in the url Output would be

Hello Hannes!

This is a 'superglobal', or automatic global, variable.
