對二維數組某一個字段相同的數組合並起來

 例子：array(3) {
  [0]=>
  array(16) {
    ["id"]=>
    string(2) "42"
    ["uid"]=>
    string(2) "14"
    ["euid"]=>
    string(2) "56"
    ["did"]=>
    string(1) "1"
    ["nid"]=>
    string(1) "0"
    ["phonetime"]=>
    string(10) "1443927600"
    ["createtime"]=>
    string(10) "1443880619"
    ["type"]=>
    string(1) "3"
    ["status"]=>
    string(1) "0"
    ["atype"]=>
    string(1) "1"
    ["mtype"]=>
    string(1) "2"
    ["endtime"]=>
    string(1) "0"
    ["time"]=>
    string(10) "10月04日"
    ["date"]=>
    string(6) "週日"
    ["uname"]=>
    NULL
    ["album"]=>
    string(0) ""
  }
  [1]=>
  array(16) {
    ["id"]=>
    string(2) "40"
    ["uid"]=>
    string(2) "14"
    ["euid"]=>
    string(2) "56"
    ["did"]=>
    string(1) "1"
    ["nid"]=>
    string(1) "0"
    ["phonetime"]=>
    string(10) "1444359600"
    ["createtime"]=>
    string(10) "1444268595"
    ["type"]=>
    string(1) "3"
    ["status"]=>
    string(1) "0"
    ["atype"]=>
    string(1) "1"
    ["mtype"]=>
    string(1) "2"
    ["endtime"]=>
    string(1) "0"
    ["time"]=>
    string(10) "10月09日"
    ["date"]=>
    string(6) "週五"
    ["uname"]=>
    NULL
    ["album"]=>
    string(0) ""
  }
  [2]=>
  array(16) {
    ["id"]=>
    string(2) "43"
    ["uid"]=>
    string(1) "2"
    ["euid"]=>
    string(2) "56"
    ["did"]=>
    string(1) "1"
    ["nid"]=>
    string(1) "0"
    ["phonetime"]=>
    string(10) "1444359620"
    ["createtime"]=>
    string(10) "1444268595"
    ["type"]=>
    string(1) "3"
    ["status"]=>
    string(1) "0"
    ["atype"]=>
    string(1) "1"
    ["mtype"]=>
    string(1) "2"
    ["endtime"]=>
    string(1) "0"
    ["time"]=>
    string(10) "10月09日"
    ["date"]=>
    string(6) "週五"
    ["uname"]=>
    NULL
    ["album"]=>
    string(0) ""
  }
}

現在想要對這個二維數組下的元素，time相同的合併到同一數組下。想要的效果爲：<pre name="code" class="php">array(2) {
  ["10月04日"]=>
  array(1) {
    [0]=>
    array(16) {
      ["id"]=>
      string(2) "42"
      ["uid"]=>
      string(2) "14"
      ["euid"]=>
      string(2) "56"
      ["did"]=>
      string(1) "1"
      ["nid"]=>
      string(1) "0"
      ["phonetime"]=>
      string(10) "1443927600"
      ["createtime"]=>
      string(10) "1443880619"
      ["type"]=>
      string(1) "3"
      ["status"]=>
      string(1) "0"
      ["atype"]=>
      string(1) "1"
      ["mtype"]=>
      string(1) "2"
      ["endtime"]=>
      string(1) "0"
      ["time"]=>
      string(10) "10月04日"
      ["date"]=>
      string(6) "週日"
      ["uname"]=>
      NULL
      ["album"]=>
      string(0) ""
    }
  }
  ["10月09日"]=>
  array(2) {
    [0]=>
    array(16) {
      ["id"]=>
      string(2) "40"
      ["uid"]=>
      string(2) "14"
      ["euid"]=>
      string(2) "56"
      ["did"]=>
      string(1) "1"
      ["nid"]=>
      string(1) "0"
      ["phonetime"]=>
      string(10) "1444359600"
      ["createtime"]=>
      string(10) "1444268595"
      ["type"]=>
      string(1) "3"
      ["status"]=>
      string(1) "0"
      ["atype"]=>
      string(1) "1"
      ["mtype"]=>
      string(1) "2"
      ["endtime"]=>
      string(1) "0"
      ["time"]=>
      string(10) "10月09日"
      ["date"]=>
      string(6) "週五"
      ["uname"]=>
      NULL
      ["album"]=>
      string(0) ""
    }
    [1]=>
    array(16) {
      ["id"]=>
      string(2) "43"
      ["uid"]=>
      string(1) "2"
      ["euid"]=>
      string(2) "56"
      ["did"]=>
      string(1) "1"
      ["nid"]=>
      string(1) "0"
      ["phonetime"]=>
      string(10) "1444359620"
      ["createtime"]=>
      string(10) "1444268595"
      ["type"]=>
      string(1) "3"
      ["status"]=>
      string(1) "0"
      ["atype"]=>
      string(1) "1"
      ["mtype"]=>
      string(1) "2"
      ["endtime"]=>
      string(1) "0"
      ["time"]=>
      string(10) "10月09日"
      ["date"]=>
      string(6) "週五"
      ["uname"]=>
      NULL
      ["album"]=>
      string(0) ""
    }
  }
}

那麼。。。代碼很簡單，沒有想象的那麼複雜，想要的結果是個三維數組

$result 爲原二維數組

 

$res = array(); //想要的結果
        foreach ($result as $k => $v) {
            $res[$v['time']][] = $v;
        }
