New Comment:
I agree with Rasmus (and I really like his story :-), but to help you
shoot yourself in the foot:
Declare and use your globals like this:
$g->id = 1000;
$g->username = "Marc";
// etc. until you have 20 of them
function fn() {
global $g;
$g->username = "Rasmus";
}
with the added benefit of auto-global for any new global var you add in
a later stage of the project.
This looks very similar to using $GLOBALS["username"] inside your
function, which is what I use if I desperately _need_ a global.
Cheerio, Marc.

This simply will not change. It is a characteristic of the language.
Perhaps you shouldn't be using 20 global variables?

"In PHP global variables must be declared global inside a function if
they are going to be used in that function."
I really think PHP should not be different from C here - or at least
there should be a setting for this. Even something like "global ALL;"
would be better, but not ideal.
The most common problem I run into by FAR is variables not being
available in the local scope. Making me register 20 of them as global
by name in every single function is counterproductive and goes against
the idea of keeping code as simple as possible. Your justification for
this is: "This can cause some problems in that people may
inadvertently change a global variable." That is a very rare problem
compared to the new problem this has introduced. JavaScript handles
this better, requiring declaration with "var" to force a variable to be
local only. I would much prefer this, and PHP doing it the way every
other language does would also be preferable.
