How often should the online status data be updated in order to maintain accurate information on user activity?

To maintain accurate information on user activity, the online status data should be updated frequently, ideally every few seconds or minutes. This ensures that users' current online status is reflected accurately in real-time. By updating the online status data regularly, the system can provide users with up-to-date information on who is currently active. 

// Update online status data every 30 seconds
$interval = 30; // in seconds

// Code to update online status data
while (true) {
    // Update online status data here

    sleep($interval); // Wait for the specified interval before updating again
}
