如何用phpmailer发送一个fpdf文件？

require 'path/to/PHPMailerAutoload.php';

$mail = new PHPMailer;
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your_email@example.com';
$mail->Password = 'your_email_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

$mail->setFrom('your_email@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Email Subject';
$mail->Body = 'Email Body';

$mail->addAttachment('path/to/fpdf_file.pdf', 'fpdf_file.pdf');

if ($mail->send()) {
    echo 'Email sent successfully.';
} else {
    echo 'Email could not be sent.';
}
