IMAP get entire message

Hi all,
Ive been struggling with this for a while, so hopefully someone can help.

This is a very simple script using PHP imap functions to read a mailbox. Is there a function I can use to get the entire source of the message (the same as I would see if I was viewing the source in outlook etc). So for a mime message I would get the entire thing, headers and everything?


<?php


    $imap = imap_open("{SERVER}", "email@domain.com", "password");
    $message_count = imap_num_msg($imap);



    for ($i = 1; $i <= $message_count; ++$i) {
        $header = imap_header($imap, $i);
        $body = imap_fetchbody($imap, $i,$partno);
        $prettydate = date("jS F Y", $header->udate);

        if (isset($header->from[0]->personal)) {
            $personal = $header->from[0]->personal;
        } else {
            $personal = $header->from[0]->mailbox;
        }
$body=imap_base64($body);
        $email = "$personal <{$header->from[0]->mailbox}@{$header->from[0]->host}>";
        echo "On $prettydate, $email said \"$body\".\n";
    }

    imap_close($imap);
