How can PHP be used to display different images for logged-in users based on new posts or threads in a forum, similar to functionality seen in some online forums?

To display different images for logged-in users based on new posts or threads in a forum, you can use PHP to check the database for any new posts or threads since the user's last visit and then display corresponding images accordingly. This can be achieved by storing the user's last visit timestamp in the database and comparing it with the timestamps of new posts or threads. 

// Assuming $lastVisitTimestamp is the timestamp of the user's last visit
// Connect to the database and query for new posts or threads since the last visit
// Display different images based on the presence of new posts or threads

if($lastVisitTimestamp) {
    $query = "SELECT COUNT(*) FROM posts WHERE post_timestamp > $lastVisitTimestamp";
    // Execute the query and fetch the result
    $newPostsCount = $result->fetchColumn();

    $query = "SELECT COUNT(*) FROM threads WHERE thread_timestamp > $lastVisitTimestamp";
    // Execute the query and fetch the result
    $newThreadsCount = $result->fetchColumn();

    if($newPostsCount > 0) {
        // Display image for new posts
        echo '<img src="new_posts_image.jpg" alt="New Posts">';
    }

    if($newThreadsCount > 0) {
        // Display image for new threads
        echo '<img src="new_threads_image.jpg" alt="New Threads">';
    }
} else {
    // Display default image for logged-in users
    echo '<img src="default_image.jpg" alt="Default Image">';
}
