Array_combine可能与UN相等数量的元素?Foreach替代品

我有一个php代码，获取名称和电子邮件，并在foreach lop中运行它们，以便它可以向应答者发送电子邮件，并将名称和电子邮件输入MySQL数据库。

我的问题是，我只能选择所有的，而不是单一的一次。如果我只选择一个被调查者，我得到Warning: array_combine(): Both parameters should have an equal number of elements，如果我选择所有的人，它没有问题。我已经尝试了一些解决方案，如$res = array_combine(array_intersect_key($arr1, $arr2), array_intersect_key($arr2, $arr1));

但是它只取顶部的名字，而不是每封邮件的确切名字。如果我选择两个调查对象，比如马克和弗雷德里克，亚历克斯和马克被插入到数据库中，而不是马克和弗雷德里克。它显示了正确的邮件，但没有名字。

是否有解决这个问题的方法?
