Re: Argh! nulls un stuff..

$var = 0; if(!is_int($var)) { echo '$var isn\'t numeric'; } and simple 'not' is going to ignore '0'. To check wherther a value is an integer use is_int() or is_numeric(), which are the same things anyway. If you care that the value is also higher than '0' add [ and $var>0] as the second condition.
