E-Mail, MIME types - breaking down by section

[The_Chancer]

I am trying to build an webmail client, and, not suprisingly, I am stuck regarding the various MIME types and how to display them.

I have a mail, which has contect types of both plain text and text / html, as well as an attachment.

The attachment can be dealt with and is produced nicely, however the body message isn't.

Is there a way of breaking down the main body into different subsections that can be dealt with and parsed differently according to the content type ?

(The answer is yes, but I don't know how to do it !!)

I have looked extensively at the imap functions within [url]http://www.php.net,[/url] but no joy as yet...

Any help / links (apart from Rogering the French Maid) would be helpful...

edited to add code...

if ($struct->type == 1) /* this is multipart body message time */
	{
		while(list($index, $sub_structure) = each($struct->parts)) 
		{ 
			for($i=0; $i< count($struct->parts); $i++) {
				$prefix=$i.".";
				if ($struct->parts[$prefix.($index+1)]->encoding ==3) {
			   		$arr["body"] = imap_base64(imap_fetchbody($this->stream, $this->msg_uid, 1, FT_UID));
			   		if(strtolower($struct->parts[$prefix.($index+1)]->subtype) == 'html') $html = 1;
			   	}
			   	else if ($struct->parts[$prefix.($index+1)]->encoding ==4) {
			   		$arr["body"] = imap_qprint(imap_fetchbody($this->stream, $this->msg_uid, 1, FT_UID));
			   		if(strtolower($struct->parts[$prefix.($index+1)]->subtype) == 'html') $html = 1;
			   	}
			}
		}
	}

Hmmm...

This works - splits multipart body mail out, decodes the right section and leaves the plain text bit alone...

if ($struct->type == 1) /* this is multipart body message time */
	{
		while(list($index, $sub_structure) = each($struct->parts)) 
		{ 
			for($i=0; $i< count($struct->parts); $i++) {
				$prefix=$i.".";
				echo "part ".$prefix.($index+1)." aka ".$struct->parts[$i]->parts[($index)]->encoding;
				if ($struct->parts[$i]->parts[($index)]->encoding ==3) {
			   		$arr["body"] = imap_base64(imap_fetchbody($this->stream, $this->msg_uid, ($prefix.$index), FT_UID));
			   		if(strtolower($struct->parts[$prefix.($index+1)]->subtype) == 'html') $html = 1;
			   	}
			   	else if ($struct->parts[$i]->parts[($index)]->encoding ==4) {
			   		$arr["body"] = imap_qprint(imap_fetchbody($this->stream, $this->msg_uid, ($prefix.$index), FT_UID));
			   		if(strtolower($struct->parts[$prefix.($index+1)]->subtype) == 'html') $html = 1;
			   	}
			   	else {
			   		$arr["body"] = imap_fetchbody($this->stream, $this->msg_uid, ($prefix.$index), FT_UID);
	    				if(strtolower($struct->subtype) == 'html') $html = 1;
			   	}
			}
		}
	}

Hope it helps someone....

Some ideas came fromhere which helped - look at the user notes..
