        <?php
            session_start();

            // Database connection
            $conn = new mysqli('localhost', 'username', 'password', 'database');

            // Check connection
            if ($conn->connect_error) {
                die('Connection failed: ' . $conn->connect_error);
            }

            // User authentication logic
            if (isset($_POST['login'])) {
                $username = $_POST['username'];
                $password = $_POST['password'];

                $stmt = $conn->prepare('SELECT * FROM users WHERE username = ? AND password = ?');
                $stmt->bind_param('ss', $username, $password);
                $stmt->execute();
                $result = $stmt->get_result();

                if ($result->num_rows > 0) {
                    $_SESSION['username'] = $username;
                    echo "Login successful!";
                } else {
                    echo "Invalid username or password.";
                }
                $stmt->close();
            }

            $conn->close();
