Here is the relevant portion of Jon's reference (illustrating &$var):
-------------------------
function swap(&$var_1, &$var_2)
{
   $temp = $var_1;
   $var_1 = $var_2;
   $var_2 = $temp;
}

$var_1 = 'I am var 1';
[etc]
-----------------------------

doesn't this need global $var_1,$var_2; in the swap function?
