多个数组与foreach？

Question

我想在PHP中的电子邮件中添加更多1个附件。我目前的代码如下。这是一个电子邮件表单，可以向电子邮件发送多个附件。

有关如何使其发挥作用的任何想法？我需要在Array $ Anhang中使用foreach循环吗？谢谢！

<?php
error_reporting(E_ALL);

function mail_att($to,$subject,$message,$anhang) 
   { 
   $absender = "xxx"; 
   $absender_mail = "xxx@xxx.com"; 
   $reply = "info@xxx.xxx"; 

   $mime_boundary = "-----=" . md5(uniqid(mt_rand(), 1)); 

   $header  ="From:".$absender."<".$absender_mail.">\n"; 
   $header .= "Reply-To: ".$reply."\n"; 

   $header.= "MIME-Version: 1.0\r\n"; 
   $header.= "Content-Type: multipart/mixed;\r\n"; 
   $header.= " boundary=\"".$mime_boundary."\"\r\n"; 

   $content = "This is a multi-part message in MIME format.\r\n\r\n";
