I believe foreach also works on a copy basis, not a pointer or reference. So if you try and alter the array you are foreach'ing it won't work as expected. For instance this: $array = array("var1", "var2", "var3"); foreach ($array as $val) { if ($val == "var2") { $val = "changed2"; } } print_r($array); Will show you that no change to $array has occurred. It's basically the same as list(), but it's worth noting. Other than backwards compliance, I've never used the list/each way of doing it. Never really had a reason too...I think it basically just comes down to user preference. -- Plutarck Should be working on something... ...but forgot what it was.
