我有一个数组,如:

Array
(
[0] => Array
    (
        [id] => 2
        [type] => comment
        [text] => hey
        [datetime] => 2010-05-15 11:29:45
    )

[1] => Array
    (
        [id] => 3
        [type] => status
        [text] => oi
        [datetime] => 2010-05-26 15:59:53
    )

[2] => Array
    (
        [id] => 4
        [type] => status
        [text] => yeww
        [datetime] => 2010-05-26 16:04:24
    )

)

任何人都可以建议一种基于日期时间元素排序/订购的方法吗？
