按键排序数组

Question

我有一个像这样的数组:

Array
(
    [0] => Array
        (
            [title] => some title
            [time] => 1279231500
        )

    [1] => Array
        (
            [title] => some title 2
            [time] => 1279231440
        )

    [2] => Array
        (
            [title] => some title 3
            [time] => 1279229880
        )
)

我怎么能根据时间对它进行排序？

Answer 1

您可以这样排序（因为它是关联数组）：

function cmp($a, $b)
{
   return strcmp($a['time'], $b['time']);
}

usort($your_array, "cmp");
print_r($your_array);
