What are the limitations of using cookies for tracking user behavior in PHP?

Limitations of using cookies for tracking user behavior in PHP include the fact that users can easily delete or block cookies, leading to inaccurate tracking data. To overcome this limitation, consider using server-side tracking methods such as session variables or database storage to track user behavior. 

// Example of using session variables for tracking user behavior
session_start();

// Set a session variable to track user behavior
$_SESSION['page_views'] = isset($_SESSION['page_views']) ? $_SESSION['page_views'] + 1 : 1;

// Retrieve and display the number of page views
echo "Page views: " . $_SESSION['page_views'];
