I believe you use globals $var to ACCESS a global variable, not to
define.
If I understand correctly, and please correct me if I am wrong, this a
way to ge around the name space...
ex. for something like
$my_var = 10;
function test () {
$my_var = 15;
}
because of these variables are in a different name space, they are not
the same.
If you intended to change the first variable, then you should do
something like
function test() {
globals $my_var;
$my_var = 15;
}
This would change the value of $my_var from 10 to 15.
Please correct me, if I'm wrong.
