I'm having difficulty trying to determine how to consistently reference part numbers (a part number such as 2.0, 2.1, 2.2 etc would refer to just the data for a plain/text message, an image/jpeg, etc). Below I'm using '1.'.$i and '2.'.$j in an attempt to reference objects in a given message. I feel like I'm close though missing something...
$mbox = imap_open('{mail.example.com:143/novalidate-cert}INBOX','someone+example.com','password');
if ($mbox) { $structure = imap_fetchstructure($mbox,$message_id);
$i = 0; $j = 0;
foreach ($structure->parts as $k1 => $d1) {//Next line, how do we refer to the part correct, e.g. "'1.'.$i"?
if (isset($d1->parts)) { foreach ($d1->parts as $j2 => $d2) {//Next line, how do we refer to the part correct, e.g. "'2.'.$j"? $a = print_r(imap_fetchbody($mbox,$cms->page2,'2.'.$j),1); echo '<div><img alt="" src="data:image/jpeg;base64,'.$a.'" /></div>'; }}}}
Also I am not interested in using any frameworks, I want to figure out how to do this myself. I'll be happy to refine my question when asked for relevant clarifications.
Before migrating emails to the database I append everything to an $email array.
Here is how the iteration over various parts of the email works. There MAY be some older bits in here that I no longer use though this works just fine. Missing functions are what I use to prepare different parts before they are written to the database.
$message = imap_body($mbox,$i);
$structure = imap_fetchstructure($mbox,$i);
$f = array('!');
$r = array('');
$message = str_ireplace($f,$r,$message);
$find = array('=00');
$replace = array('');
$message = str_ireplace($find,$replace,$message);
$message = mb_convert_encoding($message,'us-ascii','UTF-8');
$message = utf8_encode($message);
$dontattach = array('alternative','html','plain','related');
