}
?>

You will not receive emails since your computer cannot receive emails send by XAMPP - you need a receiving server set up to receive email. Even if XAMPP attempts to send an email to a valid outside email address, XAMPP is not connected to the Internet. When you run the code on a server which sends emails out, then it will work.
