PHP库生成EML电子邮件文件？

Question

我正在尝试从PHP生成EML文件.是否有任何图书馆可以让我轻松创建它们？我可以在互联网上找到一些ActiveX组件,但宁可使用更便携的东西.

Answer 1

我最终使用这种模板自己构建MIME消息,其中每个字段都被TEMPLATE_<name>变量替换:

From: TEMPLATE_FROM_ADDRESS
MIME-Version: 1.0
To: TEMPLATE_TO_ADDRESS
Subject: TEMPLATE_SUBJECT
Content-Type: multipart/mixed; boundary="080107000800000609090108"

This is a message with multiple parts in MIME format.
--080107000800000609090108
Content-Type: text/plain

TEMPLATE_BODY
--080107000800000609090108
Content-Type: application/octet-stream;name="TEMPLATE_ATTACH_FILENAME"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;filename="TEMPLATE_ATTACH_FILENAME"

TEMPLATE_ATTACH_CONTENT
--080107000800000609090108

然后使用以下方法创建最终消息非常简单str_replace:

$content = file_get_contents("Template.eml");
$content = str_replace("TEMPLATE_FROM_ADDRESS", $fromEmail, $content);
$content = str_replace("TEMPLATE_TO_ADDRESS", $toEmail, $content);
// etc. for each template parameter
// Also don't forget to base64_encode the attachment content;
$content = str_replace("TEMPLATE_ATTACH_CONTENT", base64_encode($attachContent), $content);

有关此帖子中文件附件的其他信息:附件名称和文件扩展名不在电子邮件*.eml中

编辑(2018):由于这个答案是写的,它似乎被复制并粘贴到任何地方,特别是模板.为避免与其他MIME数据发生冲突,您应确保边界"080107000800000609090108"是唯一的 - 它是一串不超过70个字符的随机字符.

我想你不需要图书馆.它只是纯文本(例如http://bitdaddys.com/example1.eml)

您只需输出带有标题的文本并使用fwrite保存即可.对于附件使用base64_encode()的规定在这里
