What are some best practices for integrating PHP and JavaScript for dynamic webpage updates?

When integrating PHP and JavaScript for dynamic webpage updates, one best practice is to use AJAX (Asynchronous JavaScript and XML) to send requests to the server without reloading the entire page. This allows for seamless updates to specific parts of the webpage. Another best practice is to separate the PHP logic (server-side) from the JavaScript functionality (client-side) to maintain a clean and organized code structure. 

<?php
// PHP code to retrieve data from the server
$data = // Retrieve data from the server

// Encode the data into JSON format
$json_data = json_encode($data);

// Output the JSON data
echo $json_data;
?>
