How can client-server communication issues impact the ability to display new posts in real-time in PHP?

Client-server communication issues, such as slow network connections or server overload, can impact the ability to display new posts in real-time in PHP by causing delays in retrieving and updating data from the server. To solve this issue, you can implement AJAX (Asynchronous JavaScript and XML) to asynchronously fetch and display new posts without reloading the entire page. 

<!-- HTML code to display new posts in real-time using AJAX -->
<div id="new-posts"></div>

<script>
    // AJAX request to fetch new posts and update the display
    function fetchNewPosts() {
        var xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                document.getElementById("new-posts").innerHTML = this.responseText;
            }
        };
        xhttp.open("GET", "fetch_new_posts.php", true);
        xhttp.send();
    }

    // Update new posts every 5 seconds
    setInterval(fetchNewPosts, 5000);
</script>
