In what ways can PHP sessions be utilized to track and manage user interactions in real-time game environments, and what are the limitations of this approach?

PHP sessions can be utilized in real-time game environments to track and manage user interactions by storing user data across multiple pages or requests. This allows for personalized experiences, game progress tracking, and user authentication. However, the limitations of using PHP sessions include potential security risks such as session hijacking, scalability issues with a large number of concurrent users, and limitations on the amount of data that can be stored in a session. 

// Start a PHP session
session_start();

// Set user data in session
$_SESSION['username'] = 'player1';
$_SESSION['score'] = 100;

// Retrieve user data from session
$username = $_SESSION['username'];
$score = $_SESSION['score'];

// Update user data in session
$_SESSION['score'] += 10;

// Destroy session when user logs out
session_destroy();
