php 嵌套多次循环for组成一维数组(多维数组变成一维数组)

表单传递过来的数据：

array(9) { ["tid747"] => array(2) { [0] => string(3) "163" [1] => string(3) "162" } ["pid"] => array(2) { [0] => string(3) "747" [1] => string(3) "750" } ["mid"] => array(2) { [0] => string(2) "14" [1] => string(2) "14" } ["tid750"] => array(1) { [0] => string(3) "162" } ["action"] => string(4) "edit" ["tid"] => string(3) "525" ["cid"] => string(3) "723" ["ccid"] => string(3) "728" ["id"] => string(3) "883"}

原多维数组：

array(2) { [0] => array(2) { [0] => array(2) { ["class_id"] => string(3) "883" ["province"] => string(3) "747" } [1] => array(2) { ["class_id"] => string(3) "883" ["province"] => string(3) "747" } } [1] => array(1) { [0] => array(2) { ["class_id"] => string(3) "883" ["province"] => string(3) "750" } }}

改变成一维数组：

array(3) { [0] => array(3) { ["class_id"] => string(3) "883" ["province"] => string(3) "747" ["tid"] => string(3) "163" } [1] => array(3) { ["class_id"] => string(3) "883" ["province"] => string(3) "747" ["tid"] => string(3) "162" } [2] => array(3) { ["class_id"] => string(3) "883" ["province"] => string(3) "750" ["tid"] => string(3) "162" }}

代码：

//保存表单试卷 if (request()->isPost()){ dump(input('')); //循环省份 if(count($pid)>0 && $id){ for($i=0;$i0){ for($n=0;$n$id, 'province' =>$pid[$i], 'tid' =>$tidarr[$n], ]; } } } if(count($dataadd)>0){// $rs = Db::name('class_test')->insert($dataadd);// if($rs){// $this->success('成功!');// }else{// $this->error('失败');// } } } dump($dataadd1); dump($dataadd);die; }
