    public function authenticate($username, $password)

// Usage example
$user = new User();

// Assuming the form data is submitted via POST
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $username = $_POST['username'];
    $password = $_POST['password'];

    if ($user->authenticate($username, $password)) {

    } else {
        // Invalid credentials
        echo 'Invalid username or password.';
    }
}

$user->closeConnection();
?>
