How can users troubleshoot login issues in PHP forums?

Users can troubleshoot login issues in PHP forums by checking if the username and password are correct, ensuring that the login form is submitting data correctly, and verifying that the login credentials are stored and retrieved accurately from the database. 

// Check if the username and password are correct
if($username == $db_username && $password == $db_password) {
    // User authentication successful
    $_SESSION['logged_in'] = true;
    header('Location: dashboard.php');
} else {
    // User authentication failed
    echo 'Invalid username or password';
}
