New Comment:
This is due that variables imported into functions with the global
statement are in fact references. There are open reports about this
issue, marking it as duplicate for now (#14645).

this is ok
<?
$a=&$b;
$a=5;
echo($b);
?>
but when I declare these variables as globals in a function it doesn't
work
<?
function foo() {
global $a, $b;
$a=&$b;
}
foo();
$a=5;
echo($b);
?>
It is probably allright. I didn't find anything about this problem.
