 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) "周日"    ["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) "周五"    ["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) "周五"    ["uname"]=>    NULL    ["album"]=>    string(0) ""  }}

现在想要对这个二维数组下的元素，time相同的合并到同一数组下。想要的效果为：<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) "周日"      ["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) "周五"      ["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) "周五"      ["uname"]=>      NULL      ["album"]=>      string(0) ""    }  }}

那么。。。代码很简单，没有想象的那么复杂，想要的结果是个三维数组

$result 为原二维数组

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