Are there specific PHP functions or libraries that can help in tracking online users effectively?

Tracking online users effectively in PHP can be achieved by using sessions or cookies to store user information. Additionally, utilizing tools like Google Analytics or custom tracking scripts can provide more detailed insights into user behavior on a website. 

// Start a session to track user activity
session_start();

// Store user information in session variables
$_SESSION['user_id'] = 123;
$_SESSION['username'] = 'john_doe';

// Track user activity using custom tracking script or Google Analytics
// Example: Google Analytics tracking code
echo "<script async src='https://www.googletagmanager.com/gtag/js?id=GA_TRACKING_ID'></script>";
echo "<script>window.dataLayer = window.dataLayer || [];function gtag(){dataLayer.push(arguments);}gtag('js', new Date());gtag('config', 'GA_TRACKING_ID');</script>";
