variable scope

I have a problem. Take this code for example:

PHP Code:


		
			
<?php



function glug() {

global $a;



    //code here

}



function blah() {



    $a = 1;



    glug();



}



blah();



?>

$a is not making it into glug() and I don't know why. It's value is nothing within the glug() function.

$a is defined in the local scope of blah(). glug() is using the global scope (a variable not defined in a function or class). The only way to pass $a is as an argument to glug(), or to make it global in the first place (not preferable).
