Are there any best practices for managing page refreshes in PHP to improve user experience?

Page refreshes in PHP can sometimes lead to a poor user experience, especially if the page takes a long time to load. One way to improve this is by using AJAX to load only the necessary content without refreshing the entire page. This can help make the user experience smoother and more responsive. 

// Example of using AJAX to load content without refreshing the page
// HTML code
<div id="content"></div>
<button onclick="loadContent()">Load Content</button>

// JavaScript code
function loadContent() {
    var xhttp = new XMLHttpRequest();
    xhttp.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            document.getElementById("content").innerHTML = this.responseText;
        }
    };
    xhttp.open("GET", "content.php", true);
    xhttp.send();
}

// content.php
<?php
echo "This is the content that was loaded using AJAX.";
?>
