In what scenarios would using AJAX be more beneficial than traditional PHP methods for updating page content?

Using AJAX would be more beneficial than traditional PHP methods for updating page content when you want to update specific parts of a page without refreshing the entire page. This can lead to a smoother and more responsive user experience. Additionally, AJAX can help reduce server load by only fetching the necessary data instead of reloading the entire page. 

// AJAX Example
<script>
function updateContent() {
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            document.getElementById("content").innerHTML = this.responseText;
        }
    };
    xhttp.open("GET", "update_content.php", true);
    xhttp.send();
}
</script>
<button onclick="updateContent()">Update Content</button>
<div id="content"></div>
