What is the issue with the user online script in the PHP forum thread?

The issue with the user online script in the PHP forum thread is that it is not updating the user's last activity time properly, causing users to appear online even when they are not actively using the site. To solve this issue, we need to update the last activity time whenever a user performs an action on the site. 

// Update the user's last activity time when they perform an action
session_start();

if(isset($_SESSION['user_id'])) {
    $user_id = $_SESSION['user_id'];
    
    // Update the last activity time in the database
    // Replace 'users' with your actual users table name and 'last_activity' with the column name for last activity
    $query = "UPDATE users SET last_activity = NOW() WHERE user_id = $user_id";
    // Execute the query using your database connection
    
    // Update the session variable with the new last activity time
    $_SESSION['last_activity'] = time();
}
