How can JavaScript be used in conjunction with PHP to achieve interactive client-side functionality?

To achieve interactive client-side functionality using JavaScript in conjunction with PHP, you can use AJAX (Asynchronous JavaScript and XML) to make asynchronous requests to the server and update parts of the webpage without reloading the entire page. This allows for dynamic and interactive user experiences. 

// PHP code snippet
<?php
// Check if AJAX request is being made
if(isset($_POST['data'])){
    // Process data received from client-side
    $data = $_POST['data'];
    
    // Perform operations on data
    
    // Return response to client-side
    echo json_encode($response);
}
?>
