What are the potential benefits of using AJAX in PHP development?

When developing web applications in PHP, using AJAX can greatly enhance the user experience by allowing asynchronous communication between the client and server. This means that certain parts of the webpage can be updated without requiring a full page reload, resulting in faster and more dynamic interactions. AJAX can also help reduce server load by only sending and receiving data as needed, leading to improved performance. 

// Example PHP code snippet demonstrating the use of AJAX in PHP development

// HTML file with AJAX script
<script>
    function fetchData() {
        var xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                document.getElementById("data").innerHTML = this.responseText;
            }
        };
        xhttp.open("GET", "fetch_data.php", true);
        xhttp.send();
    }
</script>

<button onclick="fetchData()">Fetch Data</button>
<div id="data"></div>

// fetch_data.php file
<?php
// Simulating fetching data from a database
$data = "This is the fetched data from the server.";
echo $data;
?>
