这正数组怎么变成
以cn_certification_name
为键,cn_certification_name
这字段相同的值就放在这字段下面。。
如:
<code>array(2) { ["学历证明"]=> array(4) { [0]=> array(11) { ["ce_id"]=> string(1) "1" ["ce_category_id"]=> string(1) "1" ["ce_user_id"]=> string(2) "10" ["ce_remark"]=> string(3) "123" ["ce_img"]=> string(43) "/upload/certification/1_1459410425_4041.png" ["ce_create_at"]=> string(19) "2016-03-31 15:47:05" ["ce_update_at"]=> string(19) "2016-03-31 15:47:05" ["cn_id"]=> string(1) "1" ["cn_certification_name"]=> string(12) "学历证明" ["cn_create_at"]=> string(19) "2016-03-31 10:54:02" ["cn_create_user_id"]=> NULL } [1]=> array(11) { ["ce_id"]=> string(1) "2" ["ce_category_id"]=> string(1) "1" ["ce_user_id"]=> string(2) "10" ["ce_remark"]=> string(6) "正面" ["ce_img"]=> string(43) "/upload/certification/1_1459413288_5730.png" ["ce_create_at"]=> string(19) "2016-03-31 16:34:48" ["ce_update_at"]=> string(19) "2016-03-31 16:34:48" ["cn_id"]=> string(1) "1" ["cn_certification_name"]=> string(12) "学历证明" ["cn_create_at"]=> string(19) "2016-03-31 10:54:02" ["cn_create_user_id"]=> NULL } [2]=> array(11) { ["ce_id"]=> string(1) "3" ["ce_category_id"]=> string(1) "1" ["ce_user_id"]=> string(2) "10" ["ce_remark"]=> string(6) "正面" ["ce_img"]=> string(43) "/upload/certification/1_1459413934_4724.png" ["ce_create_at"]=> string(19) "2016-03-31 16:45:34" ["ce_update_at"]=> string(19) "2016-03-31 16:45:34" ["cn_id"]=> string(1) "1" ["cn_certification_name"]=> string(12) "学历证明" ["cn_create_at"]=> string(19) "2016-03-31 10:54:02" ["cn_create_user_id"]=> NULL } } ["学历证明a"]=> array(1) { [0]=> array(11) { ["ce_id"]=> string(2) "23" ["ce_category_id"]=> string(1) "3" ["ce_user_id"]=> string(2) "10" ["ce_remark"]=> string(3) "789" ["ce_img"]=> string(43) "/upload/certification/3_1459481224_8477.png" ["ce_create_at"]=> string(19) "2016-04-01 11:27:04" ["ce_update_at"]=> string(19) "2016-04-01 11:27:04" ["cn_id"]=> string(1) "3" ["cn_certification_name"]=> string(13) "学历证明a" ["cn_create_at"]=> string(19) "2016-04-01 11:26:11" ["cn_create_user_id"]=> NULL } } } </code>

这应该是你想要的意思了
<code>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; }</code>
<code class="php">// 来个简单的 $res = []; foreach($arr as $v){ $res[$v['cn_certification_name']][] = $v; }</code>
你是要按照字段cn_certification_name排序吗?是这意思?
你是想实现二维数组转多维吧 比如爹下面有儿子儿子下面有儿子 然后这条关系都挂在同同一条数据下面
foreach($ARR as $VALUA) 这个
(strval)$;
typeof( )
用这三个函数,做不到吗?
