我使用的是最新版本的 PEAR mail_mime 模块我遇到了一个奇怪的问题。将 HTML 图像附加到电子邮件时，文本部分将无法正常工作。我所说的“无法正常工作”是指，如果我尝试在 Thunderbird 中以文本形式查看消息（或在 PINE 中查看消息），它不会显示我设置为电子邮件“文本”部分的内容；它尝试以文本可读的方式解析 HTML 信息。 HTML 部分中的所有内容都按预期工作。
这是我的精简代码：
//Headers
$headers['From'] = "[email protected]";
$headers['To'] = "[email protected]";
$headers['Subject'] = "A MIME Email";
//Text Portion
$text = "This is the text portion.";
//HTML Portion
$html = "<html><body><p><img src='image.png' />This is the HTML portion.</p></body></html>";
//Set up the MIME email
$mime = new Mail_mime(array('eol' => "\r\n"));
$mime->setTXTBody($text);
$mime->setHTMLBody($html);
$mime->addHTMLImage("/path/to/image.png", "image/png");
//Prepare the message to be sent
$body = $mime->get();
$headers = $mime->headers($headers);
//Send the message via SMTP
$mail_obj =& Mail::factory('smtp', array('host' => 'smtp.server.com', 'port' => 25));
$mail_obj->send("[email protected]", $headers, $body);
如果我注释掉 addHTMLImage 行，电子邮件的文本部分将按预期工作，并且我可以看到为非 HTML 视图设置的内容。但是，如果我取消注释该行，文本部分就会失败。查看我的消息来源，我可以看到文本部分始终存在。
以下是与此问题相关的消息源部分：

我不知道如何解决此问题。有没有人遇到类似的问题或有什么建议？
I'm using the latest version of PEAR mail_mime module and I'm running into a strange issue. When attaching HTML images to the email, the text portion stops working properly. What I mean by "not work properly" is that if I try to view the message as text in Thunderbird (or view the message in PINE), it doesn't display what I have set as the "text" portion of the email; It tries to parse the HTML information in a text readable fashion. Everything in the HTML portion works as expected.
Here's my slimmed down code:
//Headers
$headers['From'] = "[email protected]";
$headers['To'] = "[email protected]";
$headers['Subject'] = "A MIME Email";
//Text Portion
$text = "This is the text portion.";
//HTML Portion
$html = "<html><body><p><img src='image.png' />This is the HTML portion.</p></body></html>";
//Set up the MIME email
$mime = new Mail_mime(array('eol' => "\r\n"));
$mime->setTXTBody($text);
$mime->setHTMLBody($html);
$mime->addHTMLImage("/path/to/image.png", "image/png");
//Prepare the message to be sent
$body = $mime->get();
$headers = $mime->headers($headers);
//Send the message via SMTP
$mail_obj =& Mail::factory('smtp', array('host' => 'smtp.server.com', 'port' => 25));
$mail_obj->send("[email protected]", $headers, $body);
If I comment out the addHTMLImage line, the text portion of the email works as expected and I can see the content I've set for a non-HTML view. However, if I uncomment out the line, the text portion fails. Looking at the source of my message, I can see the text part is always there.
Here is the part of the message source that is relevant to this question:

I'm at a loss on how to possibly fix this. Any body run into a similar issue or have any suggestions?

这是您的邮件阅读器。如果启用 HTML 邮件，它会隐藏文本邮件。在 Gmail 中，您可以查看详细信息，也可以在仅限文本电子邮件的阅读器中查看
it's your mail reader. it hides text mail if HTML mail is enabled. in gmail you can view details or you can check it in a text email only reader
