REFERED to global variable
How we can unset global variable with all referenced variable using
unset() function? Do we must user assign to null?

<?php
function a( &$foo) {
$foo = 'ok';
b( $foo);
var_dump( $foo);
}
function b( &$foo) {
$foo = 'not ok';
unset( $GLOBALS['foo']);
}
global $foo;
$foo = 'global';
a($foo);
var_dump( $foo);
?>
Expected result:
----------------
NULL NULL
Actual result:
--------------
string(6) "not ok" NULL
