使用explode插入2个数组到mysql表中

Question

以下代码是错误的，有人知道如何编写正确的代码吗？

 foreach(explode('|',$btn) as $b)
    foreach(explode('|',$param) as $p)
      DB::insert("insert into commands (buttons, parameters) values (?, ?)", [$b, $p]);

我解决了：）

这里：

$b = explode('|', $btn);
$p = explode('|', $param);
$c = array_combine($b,$p);

foreach($c as $d => $key)
    DB::insert("insert into commands (buttons, parameters) values (?, ?)", [$d, $key]);
