PHP多个一维数组合并成二维数组的简易方法

<?php  
　　$a= array(‘张三‘,‘李四‘,‘王五‘);  
　　$b= array (‘23‘,‘24‘,‘25‘);  
　　$c= array (‘北京‘,‘上海‘,‘广州‘ );  
　　foreach($a as $key=>$val){  　　　　$d[$key][‘姓名‘]=$a[$key];  
　　　　$d[$key][‘年龄‘]=$b[$key];  
　　　　$d[$key][‘城市‘]=$c[$key];  
　　}  
  
　　echo "pre"；
 　 var_dump($d);  
?>

        $param = $this->request->param(‘‘);

        $total_amount_arr = $param[‘total_amount‘];
        $student_order_list_id_arr = $param[‘student_order_list_id‘];



        $StudentOrderListModel = new \app\admin\model\StudentOrderList();

dump($total_amount_arr);
dump($student_order_list_id_arr);
        foreach($student_order_list_id_arr as $key => $val){
                $d[$val]=$total_amount_arr[$key];

            }
dump($d);die;

array(3) {
  [0] => string(2) "24"
  [1] => string(3) "543"
  [2] => string(4) "7657"
}

array(3) {
  [0] => string(1) "1"
  [1] => string(1) "2"
  [2] => string(1) "3"
}

组成的新数组

array(3) {
  [1] => string(2) "24"
  [2] => string(3) "543"
  [3] => string(4) "7657"
}
