How can session management be utilized to track user activity and update counters in PHP?

Session management can be utilized in PHP to track user activity and update counters by storing user-specific data in session variables. This allows you to keep track of user interactions across multiple pages and update counters accordingly. By starting a session, setting session variables, and updating them as needed, you can effectively monitor user activity and update counters in real-time. 

// Start a session
session_start();

// Check if counter session variable exists, if not, initialize it
if (!isset($_SESSION['counter'])) {
    $_SESSION['counter'] = 0;
}

// Update counter
$_SESSION['counter']++;

// Display counter value
echo "User activity count: " . $_SESSION['counter'];
