No, not "just another array" (although I agree about the function being pretty
useless!) -- $GLOBALS is a superglobal array that contains a reference to every
variable defined in the global scope, so that accessing $GLOBALS['var'] from
anywhere is the same as accessing $var in the global scope. It's a way of
referencing global variables without having to use a "global $var" statement.
I was simply pointing out how you can to "get info from function back to
script" "when you don't know the keys", which you'd just said you believed was
impossible! ;) ;)
Having done which, I proceeded to point out that:

Of course -- would I give you non-working code? (Well, on purpose, anyway! ;)
