Well the definition of $GLOBALS says:
"Contains a reference to every variable which is currently available
within the global scope of the script."
I take that to mean reference as in the & operator, so that
$GLOBALS['foo'] is a reference to $foo, and when you assign to a
reference you also assign to....
But, notwithstanding that, how about Example 12.3 at
http://php.net/global#language.variables.scope.global?
Cheers!

Hmm, that's quite ugly, what happens when defining a variable outside,
and inside a function. and then get the reference to it? Will the
first var be overwritten, and when the function ends, it will refer to
the old var again?
