Are there any best practices for integrating PHP and JavaScript to create interactive elements on a webpage?

When integrating PHP and JavaScript to create interactive elements on a webpage, it's important to use AJAX (Asynchronous JavaScript and XML) to communicate between the server-side PHP code and client-side JavaScript code. This allows for dynamic content updates without reloading the entire page. Additionally, make sure to properly sanitize and validate user input to prevent security vulnerabilities. 

// PHP code snippet for handling AJAX requests
if(isset($_POST['data'])) {
    $data = $_POST['data'];
    
    // Process the data and return a response
    $response = process_data($data);
    
    // Send the response back to the client
    echo json_encode($response);
}
