Global unavailable?

[Marcus Bointon <marcus@xxxxxxxxxxxxxxxxxx>]

I have a simple situation:

in a.inc.php:

$a = 1;

in b.class.php

require 'a.inc.php';
class b {
    function test() {
        global $a;
        echo $a;
    }
}

With this pattern, $a is NOT visible within class b, even though it  
is declared in the global scope and I'm using the global keyword! I  
can work around it two ways; by changing the original declaration  
(which just seems wrong - it's already in the global scope at this  
point):

global $a;
$a = 1;

or by requiring the inc file inside each function of b (much less  
efficient):

class b {
    function test() {
        require 'a.inc.php';
        global $a;
        echo $a;
    }
}

Is this just how it is, or am I doing something wrong?
