使用php

Question

您好，我已经编写了用于联系邮件功能的代码，一切正常，但是在发送邮件后显示消息为已发送邮件的问题无法重定向另一个页面。

             <?php
            require_once('class.phpmailer.php');
             // include("class.smtp.php"); // optional, gets called from within 
              class.phpmailer.php if not already loaded
               $name = $_POST['form_name'];
            $email = $_POST['form_email'];
            $phone = $_POST['form_phone'];
             $subject = $_POST['form_subject'];
              $messages = $_POST['form_message'];
                    $mail    = new PHPMailer();
                     $smtp_host         = "HOST";
                   $smtp_user       = "USER";
                    $smtp_password  = "SECRET";
                   $smtp_port       = "25";
               $mail_from       = $email;
              $mail_to      = "MAILTO";
              $mail_to_name     = "MAILNAME";

              $message = array();    
              $message[]= 'Name  :  '.trim($name).' ';
              $message[]='Phone  :  '.trim($phone).' ';   
              $message[]='Email  :  '.trim($email).' ';   
              $message[]='Message  :  '.trim($messages).' ';    
              $message = implode('<br/>', $message);    
               $mail->IsSMTP(); // telling the class to use SMTP
               $mail->Host       = "{$smtp_host}";  // SMTP server
               $mail->SMTPDebug  = 2;                  // enables SMTP debug 
               information (for testing)
                                    // 1 = errors and messages
                                    // 2 = messages only
                $mail->SMTPAuth   = true;               // enable SMTP authentication
                $mail->Host       = "{$smtp_host}";     // sets the SMTP server
                $mail->Port       = $smtp_port;         // set the SMTP port for the GMAIL server
             $mail->Username   = "{$smtp_user}";    // SMTP account username
             $mail->Password   = "{$smtp_password}"; // SMTP account password
             $mail->SetFrom("{$mail_from}", "{$mail_from_name}");
             $mail->Subject    = "$subject";
             $mail->MsgHTML($message);

            $address = "{$mail_to}";
            $mail->AddAddress($address, "{$mail_to_name}" );
            if(!$mail->Send()) {
               echo  "Error while sending email"; 
               } else {
                 echo "message sent";
            header("Location:contact.html");
             }

我遇到此错误：
