$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('recipient1@example.com', 'Recipient 1');
$mail->addAddress('recipient2@example.com', 'Recipient 2');
$mail->addCC('cc@example.com', 'CC');
$mail->addBCC('bcc@example.com', 'BCC');

$mail->Subject = 'Test Email';
$mail->Body = 'This is a test email.';
$mail->addAttachment('path/to/file.pdf', 'Attachment.pdf');

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