將數組中某一元素值相同的追加到該數組

 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,想實現為下面的數組,數組中sendStatus=1表示發送成功sendStatus=0表示失敗，num=1，表示為1條資訊，時間取最大時間，我是想把數組組合成方便遍曆的模式。請教怎麼寫，

 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]=>        ))

回複討論(解決方案)

成功了。謝謝版主的支援，邏輯原來是這樣的!，
