there's nothing special about globals.
It's for globalising variables defined
outside of a function.
i think you dont need it.
to pass use:
my_function ($var);
try "echo $var" inside the function to make
sure that it has been passed.
notice: If you want your function to be able
to change your $var , make a "call by reference"
(see the manual for that, sorry)
