What are the advantages of using AJAX over traditional page reloads for dynamic data filtering in PHP applications?

When filtering dynamic data in PHP applications, using AJAX over traditional page reloads offers several advantages. AJAX allows for asynchronous requests to the server, resulting in faster loading times and a smoother user experience. It also enables real-time updates without the need to refresh the entire page, reducing server load and improving overall performance.

// PHP code snippet for filtering dynamic data using AJAX

// Check if the request is an AJAX request
if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    
    // Process the filtering logic here
    
    // Return the filtered data as a JSON response
    echo json_encode($filteredData);
    exit;
}
