Can PHP sessions be used to track user activity on a website effectively?

PHP sessions can be effectively used to track user activity on a website by storing relevant information in session variables such as login status, user ID, last activity timestamp, etc. By updating these variables on each page load, you can track user interactions and monitor their activity. Additionally, you can set session timeouts to automatically log out inactive users. 

// Start the session
session_start();

// Update last activity timestamp
$_SESSION['last_activity'] = time();

// Check if user is logged in
if(isset($_SESSION['user_id'])){
    // User is logged in, track their activity
    // Add code here to monitor user activity
} else {
    // User is not logged in, handle accordingly
}
