Answer 1

Use a header instead and make sure you have no output before header.

if(!$mail->Send()) {
    header("Location: http://www.example.com");
    exit;
    }

If that does not work for you, use a meta refresh method:

if(!$mail->Send()) {
$to = "http://www.example.com";
    $url = $to;
    print "";
    exit;
}

or display a message and redirect after 5 seconds:

if(!$mail->Send()) {
$to = "http://www.example.com";
    $url = $to;
    print "";
    print "Thank you for your message.";
    exit;
}

Edit: (cookie/token method)

You can use a cookie and this is just an example.

You can not submit this form twice.
