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.

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).

Achja, and it's a documentation problem . . .

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.

Thank you for your interest in PHP.
