parse email

[thetxt]

I'm trying to extract information from a raw e-mail. I'm using a parseMail() class to parse out all of the header information and content information. I am having trouble figuring out the best way to get the e-mail body. JUST the text of the e-mail. Any suggestions?

Where are the messages stored?

I have a catch all script that parses the mail and sorts it into my mysql database accordingly. I've been doing some testing just grabbing the mail from a text file.

 

Here is the class I am using to parse everything else. I've tried different ways to modify it to grab the message body as well but no luck.

Here is my test catchall script:

 

<?php

$email = file_get_contents("email.php");

require("parse_class.php");
// parse that file
$msg = new parseMail($email);

$from = eregi("<([^>]+)>",$msg->from,$arr);
$from = $arr[1];
$mybody = "from: ".$from;
$mybody .= "<br>subject: ".$msg->subject;
$mybody .= "<br>date: ".$msg->date;
$mybody .= "<br>received: ".$msg->received;
$mybody .= "<br>message: <br>".$body;

$mybody .= "<br>-------------endmail-------------<br>";
print_r("<pre>$mybody</pre>");
print_r($msg);

?>

 

This is something I've tried to grab the body but it still brings back the content type stuff. I'm in the middle of working on this code right now so it might not make complete sense:

// empty vars
$from = "";
$subject = "";
$headers = "";
$message = "";
$isheader = true;
$endmsg = false;

// handle email
$lines = explode("\n", $email);

for ($i=0; $i < count($lines); $i++) {
    if (!$endmsg) {
	if (!$isheader) {
		if (trim($lines[$i])=="") {
		// not a header, but message
		$body .= $lines[$i]."\n";

		// look out for end of message part
		if (preg_match("/^------=_Part_(.*)/", $lines[$i], $matches)) {
			$endmsg = true;
		}
	}

	if (trim($lines[$i])=="") {
		// empty line, header section has ended
		$isheader = false;
	}
}
}

Anyone have any suggestions?
