How can progressive enhancement be applied to improve user experience when using PHP and JavaScript together?

Progressive enhancement can be applied to improve user experience when using PHP and JavaScript together by ensuring that the core functionality of a website is accessible even if JavaScript is disabled. One way to achieve this is by using PHP to handle the server-side logic and rendering the initial content, while JavaScript can be used to enhance the user interface and provide additional interactivity.

    <?php
        // PHP code to fetch and display dynamic content
        $dynamic_content = "This content is fetched using PHP.";
        echo "<p>$dynamic_content</p>";
    ?>
    
    <button onclick="loadMoreContent()">Load More Content</button>
    
    <script>
        function loadMoreContent() {
            // JavaScript code to fetch and display additional content
            var additional_content = "This content is fetched using JavaScript.";
            var paragraph = document.createElement("p");
            paragraph.textContent = additional_content;
            document.body.appendChild(paragraph);
        }
