A much better way of addressing the ID problem is as follows:
function valid_id($id) {
if (strval(intval($id)) === $id) return true;
else return false;
}
This will not allow entries like "12." or a blank entry. It will allow positive or
negative integers. You can disallow negative integers by adding " && $id >= 0"
to the if expression.
