Prepare email body for PHPMailer - php

Question

I stuck in a problem using 1C-Bitrix framework with PHPMailer. The problem connected with the email body.
1C-Bitrix framework prepares body depending on options enabled. For example, if I turn on the option "Create text vesion of html-email" the body will look like this:
---------alt8045b59706
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This is my email
---------alt8045b59706
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: 8bit
<h1> This is my email </h1>
---------alt8045b59706--
If I the email template will have an attached txt file, the body will look like this:
---------mix4215b5973f
Content-Type: multipart/alternative; boundary="-------alt3795b5973f"
---------alt3795b5973f
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This is my email
---------alt3795b5973f
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: 8bit
<h1> This is my email </h1>
---------alt3795b5973f--
---------mix4215b5973f
Content-Type: text/plain; name="=?UTF-8?B?dGVzdC50eHQ=?="
Content-Transfer-Encoding: base64
Content-ID: <427605>
dGVzdCB0ZXh0Cg==
---------mix4215b5973f--
And, finally, the standard email body will look like this:
<h1> This is my email </h1>
I can't just feed such email body to PHPMailer. It doesn't work correctly. I tried msgHtml() - also doesn't work.
But standard php mail() func works well with such email body.
I found that in PHPMailer I need to set Body and AltBody separately. But then, what is the best way for me to parse such email body.
Maybe somebody knows a tool for it?
Or PHPMailer has a built in methods for it?
Maybe I need to just manually set correct "Content-Type" header (framework tells me correct Content-Type)
Thanks, in advance.

You don't need to think about those things - PHPMailer does it for you. This is all you need to do to make that structure:
$mail->isHTML();
$mail->Body = '<h1> This is my email </h1>';
$mail->AltBody = 'This is my email';
$mail->addAttachment('path/to/file.pdf');
Also, the MIME structure in the example you gave for the message body with an attachment is incorrect, so I wouldn't expect it to work in any context.
