我想创建.eml带有多个附件格式的电子邮件文件。附件已生成并且附件的内容是正确的。但附件始终采用.dat格式，文件名为“ATT00001”、“ATT0002”..等

目前我正在关注this stackoverflow question中给出的解决方案，我的代码如下

PHP

   foreach($reports as $pdf){
        $attachment = file_get_contents("auto_report_attachments\\Template_Attachment.eml");
        $attachment = str_replace("TEMPLATE_MIME_TYPE", $pdf['type'], $attachment);
        $attachment = str_replace("TEMPLATE_FILE_NAME", $pdf['filename'], $attachment);
        $attachment = str_replace("TEMPLATE_ATTACHMENT_CONTENT", base64_encode($pdf['file']), $attachment);

        $content .= $attachment;
        unset($attachment);
    }

模板附件

--080107000800000609090108
Content-Type: "TEMPLATE_MIME_TYPE"
name="TEMPLATE_FILE_NAME"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="TEMPLATE_FILE_NAME"

TEMPLATE_ATTACHMENT_CONTENT

$content是上面链接中描述的主要电子邮件标题和正文。我的.eml文件看起来像；

MIME-Version: 1.0
Date: Tue, 16 Apr 2013 09:03:37 +0100
From: sender@emailhost.com
To: recipient@emailhost.com
Subject: Email subject
Content-Type: multipart/mixed; boundary="080107000800000609090108"

This is a message with multiple parts in MIME format.

上面的base64内容给出了文件中正确的内容，PDF当文件通过选择以打开时打开PDF Reader。但是这些文件没有.pdf格式。.xls和.doc所有其他文件类型也是如此。所有文件均.dat采用标准命名格式而不是指定名称。

请帮我解决这个附件进来所需file type的指定文件名。

注意：base64示例.eml文件中的内容被截断

我自己找到了答案..!! 的标题Template_Attachment应该如下

--080107000800000609090108
Content-Type: TEMPLATE_MIME_TYPE;name="TEMPLATE_FILE_NAME"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;filename="TEMPLATE_FILE_NAME"

TEMPLATE_ATTACHMENT_CONTENT

在这种情况下，边界在哪里080107000800000609090108，并且在所有附件的末尾，应该有另一个080107000800000609090108来结束电子邮件。

希望有一天这会对某人有所帮助:-)

PS：所以实际.eml文件如下所示，它应该可以完美运行
