将数组中某一元素值相同的追加到该数组

 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，

 Array(    [0] => Array        (            [sendPhone] => 15670015154            [sendDate] =>  2015-01-12 02:28:18            [success] =>1,            [failure]=>2,       )                             [1] => Array        (            [num] => 1            [sendPhone] => 15518788555            [sendDate] => 2015-01-12 02:05:10            [success] => 1,            [failure]=>1        )    [2] => Array        (            [num] => 1            [sendPhone] => 15518788544            [sendDate] => 2015-01-12 02:11:38            [success] => 1,            [failure]=>        ))

成功了。谢谢版主的支持，逻辑原来是这样的!，
