Locate HTML and plain text using imap_fetchstructure - php

Question

I want to locate the html and/or the plain text using the imap_fetchstructure.
I tried several solutions but the emails don't have always the same structure.
I'm actually using:
$message=imap_fetchbody($inbox, $number, "1.2.1");
if ($message== "") {
$message =imap_fetchbody($inbox, $number, "1.1");
}
if ($message== "") {
$message = imap_fetchbody($inbox, $number, "1");
}
$message = imap_qprint($body);
When trying this; the result is sometimes correct and sometimes returning The content of the attachements depending on the mail server.
So I want a solution based on Imap_fetchstructure.

Answer 1

I found an answer for my question:
function getBody($uid, $imap) {
$body = $this->get_part($imap, $uid, "TEXT/HTML");
// if HTML body is empty, try getting text body
if ($body == "") {
$body = $this->get_part($imap, $uid, "TEXT/PLAIN");
}
return $body;
}
function get_part($imap, $uid, $mimetype, $structure = false, $partNumber = false) {
if (!$structure) {
$structure = imap_fetchstructure($imap, $uid, FT_UID);
}
if ($structure) {
if ($mimetype == $this->get_mime_type($structure)) {
if (!$partNumber) {
$partNumber = 1;
}
$text = imap_fetchbody($imap, $uid, $partNumber, FT_UID);
switch ($structure->encoding) {
case 3: return imap_base64($text);
case 4: return imap_qprint($text);
default: return $text;
}
}
// multipart
if ($structure->type == 1) {
foreach ($structure->parts as $index => $subStruct) {
$prefix = "";
if ($partNumber) {
$prefix = $partNumber . ".";
}
$data = $this->get_part($imap, $uid, $mimetype, $subStruct,
$prefix. ($index + 1));
if ($data) {
return $data;
}
}
}
}
return false;
}
function get_mime_type($structure) {
$primaryMimetype = array("TEXT", "MULTIPART", "MESSAGE", "APPLICATION",
"AUDIO", "IMAGE", "VIDEO", "OTHER");
if ($structure->subtype) {
return $primaryMimetype[(int)$structure->type] . "/" . $structure->subtype;
}
return "TEXT/PLAIN";
}

You can use like this to separate from html and plaintext:
$inbox = imap_open($hostName,$userName,$pwd) or die('Cannot connect (Allow gmail IMAP): ' . imap_last_error());
$emails = imap_search($inbox,'UNSEEN');
if($emails){
rsort($emails);
foreach($emails as $email_number){
$structure = imap_fetchstructure($inbox, $email_number);
if(isset($structure->parts) && is_array($structure->parts) && isset($structure->parts[1])) {// IF HTML
$part = $structure->parts[1];
$receivedEmailContent = imap_fetchbody($inbox,$email_number,2);
if($part->encoding == 3) {
$receivedEmailContent = imap_base64($receivedEmailContent);
} else if($part->encoding == 1) {
$receivedEmailContent = imap_8bit($receivedEmailContent);
} else {
$receivedEmailContent = imap_qprint($receivedEmailContent);
}
}else{//IF NOT HTML
$receivedEmailContent = imap_fetchbody($inbox,$email_number,1);
if($structure->type == 0){
$receivedEmailContent = imap_base64($receivedEmailContent);
}else{
$receivedEmailContent = imap_qprint($receivedEmailContent);
}
}
$receivedEmailContent = strip_tags($receivedEmailContent);
$header = imap_headerinfo ( $inbox, $email_number);
$receivedEmailTitle = $header->subject;
$receivedEmailSenderName = $header->from[0]->personal;
$receivedEmailSenderEmail = $header->from[0]->mailbox . "#" . $header->from[0]->host;
}
}
imap_close($inbox);
