php數組如何轉化成如下數組...

Array(    [0] => Array        (            [ce_id] => 1            [ce_category_id] => 1            [ce_user_id] => 10            [ce_remark] => 123            [ce_img] => /upload/certification/1_1459410425_4041.png            [ce_create_at] => 2016-03-31 15:47:05            [ce_update_at] => 2016-03-31 15:47:05            [cn_id] => 1            [cn_certification_name] => 學曆證明            [cn_create_at] => 2016-03-31 10:54:02            [cn_create_user_id] =>         )    [1] => Array        (            [ce_id] => 2            [ce_category_id] => 1            [ce_user_id] => 10            [ce_remark] => 正面            [ce_img] => /upload/certification/1_1459413288_5730.png            [ce_create_at] => 2016-03-31 16:34:48            [ce_update_at] => 2016-03-31 16:34:48            [cn_id] => 1            [cn_certification_name] => 學曆證明            [cn_create_at] => 2016-03-31 10:54:02            [cn_create_user_id] =>         )    [2] => Array        (            [ce_id] => 3            [ce_category_id] => 1            [ce_user_id] => 10            [ce_remark] => 正面            [ce_img] => /upload/certification/1_1459413934_4724.png            [ce_create_at] => 2016-03-31 16:45:34            [ce_update_at] => 2016-03-31 16:45:34            [cn_id] => 1            [cn_certification_name] => 學曆證明            [cn_create_at] => 2016-03-31 10:54:02            [cn_create_user_id] =>         )    [3] => Array        (            [ce_id] => 4            [ce_category_id] => 1            [ce_user_id] => 10            [ce_remark] => 正面            [ce_img] => /upload/certification/1_1459414535_2607.png            [ce_create_at] => 2016-03-31 16:55:35            [ce_update_at] => 2016-03-31 16:55:35            [cn_id] => 1            [cn_certification_name] => 學曆證明a            [cn_create_at] => 2016-03-31 10:54:02            [cn_create_user_id] =>         ))

這正數組怎麼變成
以cn_certification_name為鍵，cn_certification_name這欄位相同的值就放在這欄位下面。。

這應該是你想要的意思了

function changeArray($arr){        $newArr = $keyTmp =  array();        foreach($arr as $val){            array_push($keyTmp, $val['cn_certification_name']);        }        unset($val);        $keyTmp = array_unique($keyTmp);        foreach($arr as $val){            foreach($keyTmp as $tmpVal){                if($val['cn_certification_name'] == $tmpVal){                    $newArr[$tmpVal][] = $val;                }            }        }        return $newArr;    }

// 來個簡單的$res = [];foreach($arr as $v){     $res[$v['cn_certification_name']][] = $v;}

你是要按照欄位cn_certification_name排序嗎？是這意思？

你是想實現二維數組轉多維吧 比如爹下面有兒子兒子下面有兒子 然後這條關係都掛在同同一條資料下面

foreach($ARR as $VALUA) 這個

(strval)$;

typeof( )

用這三個函數,做不到嗎?
