All I have to go by is what I see. The method was this..
<?
$get_allow = array('foo', 'bar', 'add', 'takeovertheworld');
while (list($key,$val)=each($get_allow))
{
if (isset($_GET[$key]))
$$key = $val;
}
?>
The array $get_allow has numerical indicies. Looping through that in the
method described is going to set an integer to $key. So your first error is
going to be that $_GET[0] is Undefined. Second error is going to be $$key
is an invalid variable name.
