PHP - HTML Email and Mime Types?

programming
1

I have a php script which should be sending a HTML formatted email. I currently have it set up like so:


        $email_sender = "Broker King";
        $email_subject = "Thank You For Playing Pac-Mini!";        
        $message = "<html>
          <body>
          <img src='http://www.duncanhall.net/pacmini/logo.jpg' />
          <br><br><br>
          <font face='tahoma' size='2'>
            You managed to complete the game and scored <b>$score</b> with a time of <b>$time</b> - well done! 
            Thanks again for playing, and remember - you can play and submit your score as many times as you like.
            <br><br><br>
            <b>BROKER KING<b>
            </font>
          </body>
        </html>";
    
        $headers = "MIME-Version: 1.0rn";
        $headers .= "Content-type: text/html; charset=iso-8859-1rn";
        $headers  .= "From: $email_sender
";
       
        mail($emailAddress, $email_subject, $message, $headers);

Hotmail manages to render this exactly as I would like, but Outlook and Yahoo mail simply spit out the HTML tags as plain text. Does anyone know how I can rectify this, or know of a better solution?
