Array
(
    [0] => Array
        (
            [num] => 1
            [sendPhone] => 15670015154
            [sendDate] => 2015-01-12 01:19:57
            [sendStatus] => 1
        )

    [1] => Array
        (
            [num] => 1
            [sendPhone] => 15518788555
            [sendDate] =>  2015-01-12 02:28:18
            [sendStatus] => 0
        )

    [2] => Array
        (
            [num] => 1
            [sendPhone] => 15518788555
            [sendDate] => 2015-01-12 02:05:10
            [sendStatus] => 1
        )

    [3] => Array
        (
            [num] => 1
            [sendPhone] => 15518788544
            [sendDate] => 2015-01-12 02:11:38
            [sendStatus] => 1
        )

    [4] => Array
        (
            [num] => 2
            [sendPhone] => 15670015154
            [sendDate] => 2015-01-12 02:28:18
            [sendStatus] => 0
        )

)

sendPhone是相同的,想实现为下面的数组,数组中sendStatus=1表示发送成功sendStatus=0表示失败，num=1，表示为1条信息，时间取最大时间，我是想把数组组合成方便遍历的模式。请教怎么写，
