In Outlook does not parse correctly when email is sent as hmtl

I use this code which I fountd on php.net

I just spent a few hours working on getting a simple html formatted
email to work on outlook. This is the end result:

<?php
$body="<em>HTML</em> formatted <strong>Message</strong";

$headers = "From: info@example.com \r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1 ";
$headers .= "MIME-Version: 1.0 ";
/*notice there aren't any \r\n after the second two header additions.
This is what made this version work correctly*/
mail("john@example.com", "An HTML Message", $body, $headers);
?>


the body shows up as a text/plain

Outlook is broken in many regards, but this is not one of them. Try
viewing the source of an email which seems to behave correctly in
Outlook. You should find that it complies with rfc2183 - i.e. the
content-disposition on the HTML MIME section is inline.
