Hello guys, 
I'm testing a 
PHP mail form, a very barebones one, found here:
<?php
    if(isset($_POST['submit']))
    {
        //The form has been submitted, prep a nice thank you message
        $output = '<h3>Thanks for your message</h3>';
        //Deal with the email
        $to = '
[email protected]';
        $subject = 'you have a mail';
        $contactname = strip_tags($_POST['contactname']);
        $adress = strip_tags($_POST['adress']);
        $contactemail = strip_tags($_POST['contactemail']);
        $textmessage = strip_tags($_POST['textmessage']);
        $boundary =md5(date('r', time())); 
        $headers = "From: My Site\r\nReply-To: 
[email protected]";
        $message = "Name: ".$contactname."\n";
        $message .= "Adress: ".$adress."\n";
        $message .= "E-mail: ".$contactemail."\n";
        $message .= "Message: ".$textmessage."\n";
        mail($to, $subject, $message, $headers);
    }
?>
The problem is I'm receiving an unwanted slash "\" everytime I write a single or a double quote in my message, so "I'm" appear as "I\'m" in my mailbox.
I know it have to do with the way 
PHP distinguishes code quotes from only lecture quotes, but I wouldn't know what to add in my form to get it properly running.
Any help is appreciated,
