How can timestamps be effectively used to track new posts for users in a PHP forum?

To track new posts for users in a PHP forum, timestamps can be effectively used by storing the timestamp of the last visit for each user and comparing it to the timestamps of new posts. This way, users can easily see which posts are new since their last visit. 

// Assuming $last_visit_timestamp is the timestamp of the user's last visit
// $new_posts is an array of posts with timestamps

foreach ($new_posts as $post) {
    if ($post['timestamp'] > $last_visit_timestamp) {
        echo "New post: " . $post['title'];
    }
}
