How to extract only HTML from imap_body result - php

Question

I want to extract only the HTML content from a imap_body result.
The imap_body give a verbatim copy of the mail.

Answer 1

I found a solution:
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)
{
$primaryMimetype = ["TEXT", "MULTIPART", "MESSAGE", "APPLICATION", "AUDIO", "IMAGE", "VIDEO", "OTHER"];
if ($structure->subtype) {
return $primaryMimetype[(int)$structure->type] . "/" . $structure->subtype;
}
return "TEXT/PLAIN";
}

http://php.net/manual/en/function.imap-fetchbody.php
Parameter 3, "the section" is as follows:
The part number. It is a string of integers delimited by period which index into a body part list as per the IMAP4 specification
(empty) - Entire message
0 - Message header
1 - MULTIPART/ALTERNATIVE
1.1 - TEXT/PLAIN
1.2 - TEXT/HTML
2 - file.ext
Therefore, to grab the HTML part of the mail, you would have to use the 1.2 option as the third parameter. Like so:
$message = imap_fetchbody($inbox, $number, 1.2);

Answer 3

I don't have enough reputation to add a comment, but I just wanted to clarify in #GunniH's answer that your call to the function should look like this:
$message = imap_fetchbody($inbox, $number, '1.2');
instead of this
$message = imap_fetchbody($inbox, $number, 1.2);
That final argument should be a string, not an int.
