In what ways can PHP developers work around the server-side nature of PHP to achieve client-side effects like frame refreshing?

PHP developers can achieve client-side effects like frame refreshing by using AJAX (Asynchronous JavaScript and XML) to send requests to the server and update parts of the webpage dynamically without reloading the entire page. This allows for a smoother user experience and the ability to update content without disrupting the user's current interactions on the page. 

// PHP code snippet using AJAX to achieve frame refreshing
<?php
// Check if AJAX request is being made
if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    // Code to process AJAX request and return updated content
    // For example, updating a specific div element with new content
    echo "<div>New content here</div>";
    exit();
}
?>

        // AJAX request to update content without refreshing the page
        function refreshFrame() {
            $.ajax({
                url: 'your_php_file.php',
                type: 'post',
                success: function(response) {
                    $('#your_div_id').html(response);
                }
            });
        }
        // Call the function to refresh the frame on page load or button click
        $(document).ready(function() {
            refreshFrame();
            // Example: Refresh frame every 5 seconds
            setInterval(refreshFrame, 5000);
        });
