Undefined index means exactly what it says. The index "BLAH" does not yet exist within the $_GET array. You need to check for it's existence before attempting to use it's value. if (isset($_GET['BLAH'])) { // safe to use }

Drupal is definitely not the first thing that comes to mind when I think about well designed applications. Have you ever heard of constants? These are perfect for storing simple strings and accessing them from anywhere. There is an entire series covering the basic design patterns on our main site (http://www.phpfreaks.com/tutorials/page2). There's an article there covering the singleton.

Your still missing the point. You could use a normal self created array. $_SERVER does not persist content you have added to it across requests. $_ENV will if you actually add these values to your environment through Apache directives.

Variables created outside of functions do not exist within functions. That's the point of functions, to create stand alone code. If you want to use $mode within your function you will need to pass it in as an argument. (And please, no one mention the globals keyword, globals break encapsulation)
