Description:
------------
unset( $GLOBALS['foo']); unset only global variable, not variables that
REFERED to global variable
How we can unset global variable with all referenced variable using
unset() function? Do we must user assign to null?
Reproduce code:
---------------
<?php
function a( &$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
