    [1] => stdClass Object
        (
            [id] => 2
            [message] => b

        )

    [2] => stdClass Object
        (
            [id] => 1
            [message] => a
        )

    [3] => stdClass Object
        (

            [id] => 4

PHP provides the usort function for this: usort documentation

$sortedArray = usort($array, function($a, $b) {
        return $a->id - $b->id;
    });
