PHP array multidimensional sorting

Question

I have a multi-dimensional array like so.

[0] => Array
    (
        [time] => 1312206805
        [item] => email@example.net created ad ad.
    )

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

[2] => Array
    (
        [time] => 1312130982
        [item] => info@example.org created an ad.
    )

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

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
