PHP多个一维数组合并成二维数组的简易方法
当我们需要进行数组遍历数据的时候,需要将多个一维数组进行二维的转换,方法很简单。如下:
<?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" }
