Not correct.
Variables used in the global scope are global, and appear in the $GLOBALS array as
soon as they come into existence. A global statement is used within a function merely
to declare that you wish to use one of those variables in that function, where it
would otherwise not be available. It's sort of equivalent to saying "when I use
variable $x in this function, I actually want it to be $GLOBALS['x']" -- or, in PHP
terms, $x = &$GLOBALS['x'].

I'm really not sure what you're getting at here, but I think it may be based on a
misunderstanding. If you could explain exactly what it is you're trying to do,
someone might be able to offer some better help.
