I know, and it can be done without typing so much:

class SortByKey {
    function __call($name, $a) {
        if ($a[0][$name] < $a[1][$name])
            return -1;
        if ($a[0][$name] == $a[1][$name])
            return 0;
        return 1;
    }
}
$a = array(
    array("a" => 1, "b" => 2),
    array("a" => 2, "b" => 1),
);
usort($a, array(new SortByKey, "b"));

That doesn't change the fact that it's a hack ;)
