发送邮件后重定向到感谢页面

我想在将邮件发送到活动页面后重定向页面。下面是我的PHP联系人表单页面。现在我想在发送邮件后重定向到我的"谢谢"页面。

//check if its an ajax request, exit if not
if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
    $output = json_encode(array( //create JSON data
        'type'=>'error', 
        'text' => 'Sorry Request must be Ajax POST'
    ));
    die($output); //exit script outputting json data
} 
//Sanitize input data using PHP filter_var().
$user_name      = filter_var($_POST["user_name"], FILTER_SANITIZE_STRING);
$user_email     = filter_var($_POST["user_email"], FILTER_SANITIZE_EMAIL);
$phone_number   = filter_var($_POST["phone_number"], FILTER_SANITIZE_NUMBER_INT);
$message        = filter_var($_POST["msg"], FILTER_SANITIZE_STRING);
//additional php validation
if(strlen($user_name)<4){ // If length is less than 4 it will output JSON error.
    $output = json_encode(array('type'=>'error', 'text' => 'Name is too short or empty!'));
    die($output);
}
if(!filter_var($user_email, FILTER_VALIDATE_EMAIL)){ //email validation
    $output = json_encode(array('type'=>'error', 'text' => 'Please enter a valid email!'));
    die($output);
}
if(!filter_var($phone_number, FILTER_SANITIZE_NUMBER_FLOAT)){ //check for valid numbers in phone number field
    $output = json_encode(array('type'=>'error', 'text' => 'Enter only digits in phone number'));
    die($output);
}
if(strlen($message)<3){ //check emtpy message
    $output = json_encode(array('type'=>'error', 'text' => 'Too short message! Please enter something.'));
    die($output);
}
//email body
$message_body = $message."'r'n'r'n"
      .$user_name."'r'nEmail : "
      .$user_email."'r'nPhone Number : ". $phone_number ;
//proceed with PHP email.
$headers = 'From: '.$from_email.'' . "'r'n" .

$send_mail = mail($to_email, $subject, $message_body, $headers);
 if(!$send_mail)

    $output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.'));
    die($output);
}else{
    $output = json_encode(array('type'=>'message', 'text' => 'Hi '.$user_name .', your message has been sent. Thank you!'));
    die($output);
}
}
?>
