帶有foreach的多個數組？

Question

我想在PHP中添加1個附件到一封電子郵件中。我目前的代碼如下。這是一個將多個附件發送到電子郵件的電子郵件表單。

關於如何讓它工作的任何想法？我需要Array $ Anhang中的foreach循環嗎？謝謝！

<?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"; 
    $content.= "--".$mime_boundary."\r\n";

$anhang["data"] = implode("",file($_FILES['Bild1']['tmp_name'])); 

mail_att("info@xxx","Email mit Anhang","Im Anhang ist eine Datei",$anhang);

你也可以遍歷所有上傳的文件：

$anhang = array(); 
foreach ($_FILES as $curfile) { 
    if (!empty($curfile['name'])) { 
     $curfile['data'] = file_get_contents($curfile['tmp_name']); 
     $anhang[] = $curfile; 
    } 
}
