My take: $number = (int) $number; if ($number < 1) $number = 1; You could error out for < 1, or compare the original with the (int) cast to see if PHP considers them = and error out if not, while using the (int) cast to be SURE you have an int, or... But a typecast and inequality test should be pretty clear and cheap.Hey, nice. Thanks!
