PHP IMAP : How to get the correct body?

Question

I am connecting to my inbox via PHP IMAP plugin. Below are my steps

Connection

//The location of the mailbox.
$hostname = '{outlook.office365.com:993/imap/ssl/novalidate-cert}';

//The username / email address that we want to login to.
$username = 'username';

//The password for this email address.
$password = 'password';

I am further opening the inbox connection and looking at anything that is UNSEEN in the inbox

//Attempt to connect using the imap_open function.

$inbox = imap_open($hostname,$username,$password);

$mailboxes = imap_list($inbox, $hostname, '*');
imap_reopen($inbox, $hostname.'INBOX');

$emails = imap_search($inbox, 'UNSEEN');

Further, I am iterating over all the emails and its working well with headers. The issue I am having is with body.

To get the body of the email I am using

//get message body
$message = quoted_printable_decode(imap_fetchbody($inbox, $email_number, 2.1));
if ($message == '') {
  $message = quoted_printable_decode(imap_fetchbody($inbox, $email_number, 1));
}

So running a test on 40 emails, 28 emails fetch the body correct and store into the database.

12 emails fetch a body which looks like

How should I be reading the body? So that I can have my test pass all the emails correctly?

Thank you

Answer 1

Also I found a way to get rid of those characters.

I looked at the encoding and I am parsing based on encoding numbers as follow

$encoding = $structure->encoding;

if($encoding == 3) {
   $finalmsg = imap_base64($message);
} else if($encoding == 1) {
   $finalmsg = imap_8bit($message);
} else {
   $finalmsg = imap_qprint($message);
}

I am still having issues when encoding type = 0. The signature is causing major problem
