please i am trying to make the message show on newline as the customer type it, but i am getting /r/n between each line and also trying to make the $body .= $_SESSION['username']; appear on a separate line the code is below

PHP Code:
$body .= $_SESSION['username'];
$body .= $message;
$to $email;
$subject "copy of your notification"
$headers "From: [email][/email]\r\n";  
$headers  .= 'MIME-Version: 1.0' "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' "\r\n";
$headers .= '' "\r\n";
HTML Code:
<form action='notification.php' method='Post' class='rl'>
    <label for='message' class='fixedwidth'>Message</label>
    <textarea name="message" rows ="7" cols="40" id="message"></textarea>

    <div class='buttonarea'>
            <input type='submit' name='notify' value='Notify'>
