// http://stackoverflow.com/a/2699110/1163000
function sort_array_by_value($key, &$array) {

    $sorter = array();
    $ret = array();

    reset($array);

    foreach($array as $ii => $value) {
        $sorter[$ii] = $value[$key];
    }

    asort($sorter);

    foreach($sorter as $ii => $value) {
        $ret[$ii] = $array[$ii];
    }

    $array = $ret;

}

Contoh Kasus 

Sampel array:

$my_array = array(
    array(
        'id' => 1,
        'title' => 'Orange',
        'time' => '2014-03-05 03:00:42'
    ),
    array(
        'id' => 2,
        'title' => 'Banana',
        'time' => '2013-01-06 13:05:15'
    ),
    array(
        'id' => 3,
        'title' => 'Grape',
        'time' => '2011-05-15 01:30:45'
    )
);

Menyortir data berdasarkan nilai dari title

sort_array_by_value('title', $my_array);

print_r($my_array);

Akan menghasilkan urutan seperti ini:

Array
(
    [1] => Array
        (
            [id] => 2
            [title] => Banana            [time] => 2013-01-06 13:05:15
        )

    [2] => Array
        (
            [id] => 3
            [title] => Grape            [time] => 2011-05-15 01:30:45
        )

    [0] => Array
        (
            [id] => 1
            [title] => Orange            [time] => 2014-03-05 03:00:42
        )
