What are the best practices for handling new posts that occur while a user is actively using a PHP forum?

When a user is actively using a PHP forum, new posts may be added by other users. To handle this, you can implement AJAX polling to periodically check for new posts without refreshing the page. This way, the user can see new posts without any interruption to their browsing experience. 

// AJAX polling to check for new posts every 5 seconds
setInterval(function(){
    $.ajax({
        url: 'check_new_posts.php',
        type: 'GET',
        success: function(data){
            // Update the page with new posts if any
            $('#posts-container').html(data);
        }
    });
}, 5000);
