How can PHP be used to track user activity and calculate resource updates based on their online status?

To track user activity and calculate resource updates based on their online status, you can use PHP to create a session management system that records user login times and updates resource usage accordingly. By storing user login times in a database and checking their activity periodically, you can determine their online status and adjust resource allocation as needed. 

// Start the session
session_start();

// Update user's last activity time in the database
function updateLastActivity($userId) {
    // Code to update last activity time in the database
}

// Check if user is online based on their last activity time
function isUserOnline($userId) {
    // Code to check if user is online based on last activity time
}

// Calculate resource updates based on user's online status
function calculateResourceUpdates($userId) {
    if (isUserOnline($userId)) {
        // Code to increase resource allocation
    } else {
        // Code to decrease resource allocation
    }
}

// Example of how to use the functions
$userId = 1;
updateLastActivity($userId);
calculateResourceUpdates($userId);
