如何使用PHPMailer在发送邮件后进行重定向

require 'path/to/PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'your_username';
$mail->Password = 'your_password';
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');

$mail->Subject = 'This is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->addAttachment('path/to/file.pdf');

if ($mail->send()) {
    header('Location: http://example.com/success.html');
} else {
    header('Location: http://example.com/error.html');
}
