The difference can be found in indexed arrays (using numbers) or
associative arrays (using texts). Using foreach() this difference is
overcome.
Yup.
If you really, really want to do it the hard way:
$n = count($_GET);
for($i = 0;$i < $n;$i++){
echo reset(array_slice($_GET,$i,1));
}
But that's just crazy.... foreach it is :P.
