Php 在Pear邮件（）上添加重定向

到目前为止，邮件发送的信息都是正确的。我正在尝试将mail.php重定向到thank.php。它最终显示标题（“位置：）

    <?php

if(isset($_POST['email'])) {
require_once "Mail.php"; //PEAR mail is already installed in our current environment

$email_to = "email@domain.com";  //Enter the email you want to send the form to
$email_subject = "Subject";  // You can put whatever subject here

$host = "subdomain.domain.com";  // The hostname of your mail server
// If your email is with HostMySite, use the actual hostname of your mail server, for example:
//   SmarterMail: mailXX.safesecureweb.com OR win-mailXX.hostmanagement.net
//   OpenX-change: smtp.hostmanagement.net
// Contact Support if you aren't sure what to enter here.

$username = "email@domain.com";  // A valid email address you have setup 
$from_address = "email@domain.com";  // If your mail is hosted with HostMySite this has to match the email address above 
$password = "p4ssw0rd";  // Password for the above email address
$reply_to = "email@outlook.com";  //Enter the email you want customers to reply to
$port = "587"; // This is the default port. Try port 50 if this port gives you issues and your mail is hosted with HostMySite

function died($error) {
// your error code can go here 
echo "We are very sorry, but there were error(s) found with the form you submitted. "; 
echo "These errors appear below.<br /><br />"; 
echo $error."<br /><br />"; 
echo "Please go back and fix these errors.<br /><br />";
die();
}

// Validate expected data exists
if(!isset($_POST['salutation']) || !isset($_POST['fname']) || !isset($_POST['lname']) || !isset($_POST['email']) || !isset($_POST['phone']) || !isset($_POST['message'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');

if (PEAR::isError($mail)) {?>
