unable to send email as both plain text and html in cakephp - php

Question

App::uses('CakeEmail', 'Network/Email');
$Email = new CakeEmail();
$Email->to($emailContentArray['To']);
$Email->from(array($emailContentArray['From'] => Configure::read('FROM_NAME')));
$Email->subject($emailContentArray['Subject']);
$Email->emailFormat('both');
$response=$Email->send($emailContentArray['Body']);
if we check the resulting email it looks like:-
Content-Type: multipart/mixed; boundary="782f009f669cbcf2faafff59fe0eeb5d"
Content-Transfer-Encoding: 8bit
X-Identified-User: {:test25.xyzzzz.com:testttt.com} {sentby:program running on server}
--782f009f669cbcf2faafff59fe0eeb5d
Content-Type: multipart/alternative; boundary="alt-782f009f669cbcf2faafff59fe0eeb5d"
--alt-782f009f669cbcf2faafff59fe0eeb5d
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: 8bit

In text/plain the email should not show the html tags - how can I get both html and plain text to be sent correctly?

Answer 1

Encode the content and the subject in base64:
"=?utf-8?b?".base64_encode($s)."?=";
And before sending the emails don't forget to set the header:
'Content-Transfer-Encoding: base64';
If I'm not wrong you can make to set header: $Email->setHeader('X-Content-Transfer-Encoding', 'base64');
You can take a look at Cakephp sending UTF-8 Emails and lineLength
