如何把数组的值变成健名形成新的数组。

(
    [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
        (
            ...............
        )
)

------解决思路----------------------

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

Array<br />(<br />    [12] => Array<br />        (<br />            [0] => Array<br />                (<br />                    [ak] => 1<br />                    [tss] => sd第三方f<br />                )<br /><br />            [1] => Array<br />                (<br />                    [ak] => 2<br />                    [tss] => 是的发生<br />                )<br /><br />        )<br /><br />    [22] => Array<br />        (<br />            [0] => Array<br />                (<br />                    [ak] => 3<br />                    [tss] => 好新玩<br />                )<br /><br />            [1] => Array<br />                (<br />                    [ak] => 4<br />                    [tss] => 八实得分<br />                )<br /><br />            [2] => Array<br />                (<br />                    [ak] => 6<br />                    [tss] => 八实得分<br />                )<br /><br />        )<br /><br />)<br /><br />
