I have a multi-dimensional array like so.

[0] => Array
    (
        [time] => 1312206805
        [item] => [email protected] created ad ad.
    )

[1] => Array
    (
        [time] => 1312206805
        [item] => [email protected] created an ad.
    )

[2] => Array
    (
        [time] => 1312130982
        [item] => [email protected] created an ad.
    )

I'd like to sort by the time, while maintaining indexes and keeping each parent array together.

possible duplicate of Sorting a multidimensional array in PHP? ... or one of other dozens like it on SO... just use uasort. –  Wrikken Aug 1 '11 at 20:10

uasort($arr,function($a,$b){
    return $a['time'] - $b['time'];
});

Requires php5.3+
If you use older version you can replace anonymous function by other callback
