(
    [0] => Array
        (
            [ak] => 1
            [fs] => 12
            [tss] => sd第三方f
        )

    [1] => Array
        (
            [ak] => 2
            [fs] => 12
            [tss] => 是的发生
        )

    [2] => Array
        (
            [ak] => 3
            [fs] => 22
            [tss] => 好新玩
        )

    [3] => Array
        (
            [ak] => 4
            [fs] => 22
            [tss] => 八实得分
        )
    [4] => Array
        (
            [ak] => 6
            [fs] => 22
            [tss] => 八实得分
        )
)

上面的数组是$abc
我下奶想形成新的数组把fs的值作为键名，然后把fs的值相同的，形成新的数组，。。

数组如下：

(
    [12] => Array
        (
   [0] => Array
         (
             [ak] => 2
             [tss] => 是的发生
         )
                  [1] => Array
         (
            [ak] => 2
            [tss] => 是的发生
        )
        )

    [22] => Array
        (
            ...............
        )
)

回复讨论(解决方案)

$ar = array (  array (    'ak' => '1',    'fs' => '12',    'tss' => 'sd第三方f',  ),  array (    'ak' => '2',    'fs' => '12',    'tss' => '是的发生',  ),  array (    'ak' => '3',    'fs' => '22',    'tss' => '好新玩',  ),  array (    'ak' => '4',    'fs' => '22',    'tss' => '八实得分',  ),  array (    'ak' => '6',    'fs' => '22',    'tss' => '八实得分',  ),);$res = array();foreach($ar as $r) {  $t = $r['fs'];  unset($r['fs']);  $res[$t][] = $r;}print_r($res);
