$mail->IsSMTP();
$mail->Host = "smtp.example.com"; // Replace with the SMTP server hostname

// Authentication (if required)
$mail->SMTPAuth = true;
$mail->Username = 'smtp_username'; // Replace with your SMTP username
$mail->Password = 'smtp_password'; // Replace with your SMTP password</code>

By utilizing SMTP, your PHPMailer script can now successfully send HTML emails, resolving the "Could not instantiate mail function" error.
