Default 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.

Default

$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).
