Are there any specific PHP functions or libraries that can streamline the process of tracking and displaying online user status in a forum setting?

To track and display online user status in a forum setting, you can use PHP sessions to store user information and update their status based on their activity. You can create a function to update user status when they log in or log out, and display the online status on the forum page using this information. 

// Start session
session_start();

// Function to update user status
function updateUserStatus($userId, $status) {
    $_SESSION['users'][$userId]['status'] = $status;
}

// Function to display online status
function displayOnlineStatus($userId) {
    if(isset($_SESSION['users'][$userId]) && $_SESSION['users'][$userId]['status'] == 'online') {
        echo 'Online';
    } else {
        echo 'Offline';
    }
}

// Example of updating user status when logging in
$user_id = 123;
updateUserStatus($user_id, 'online');

// Example of displaying online status on forum page
$user_id = 123;
echo 'User status: ' . displayOnlineStatus($user_id);
