The below example by (rustin dot phares at hotmail dot com) will not work. I read the documentation
on references and it seemed a little bit odd, according to docs when unsetting a reference you only
unset the variable's reference and the variable itself.
This won't unset $a and $b and $c. It will only unset $c.
------------------
<?php
$a = 1;
$b =& $a;
$c =& $b;
unset($c);
?>
