Zend Mail and encodings, content-transfer etc. - Unified? - email

Question

Is there any class in the Zend Framework that allows me to easily read emails?
The Zend_Mail class does allow me to easy get headers, subject and the content body. But transferring everything to UTF-8 and human-readable format is still a pain.
Or am I doing something wrong? As far as I can tell, Zend Framework does not allow me to easily get UTF-8 strings that I can just use, I still have to do some post-processing. Right?

Answer 1

The key thing is that you need to iterate over the parts within the Message and find the text. Once you have it, then you can use quoted_printable_decode to get the text itself in a useful way.
This is some rough and ready code that reads IMAP email boxes with Zend_Mail:
<?php
$mail = new Zend_Mail_Storage_Imap(array(
'host' => EMAIL_ACCOUNT_HOST,
'user' => EMAIL_ACCOUNT_USERNAME,
'password' => EMAIL_ACCOUNT_PASSWORD,
));
echo (int)$mail->countMessages() . " messages found\n";
foreach ($mail as $message) {
$from = $message->getHeader('from');
$subject = trim($message->subject);
$to = trim($message->to);
$body = getBody($message);
// do something with message here
}
function getBody(Zend_Mail_Message $message)
{
// find body
$part = $message;
$isText = true;
while ($part->isMultipart()) {
$foundPart = false;
$iterator = new RecursiveIteratorIterator($message);
foreach ($iterator as $part) {
// this detection code is a bit rough and ready!
if (!$foundPart) {
if (strtok($part->contentType, ';') == 'text/html') {
$foundPart = $part;
$isText = false;
break;
} else if (strtok($part->contentType, ';') == 'text/plain') {
$foundPart = $part;
$isText = true;
break;
}
}
}
if($foundPart) {
$part = $foundPart;
break;
}
}
$body = quoted_printable_decode($part->getContent());
}
