What are some best practices for integrating PHP and JavaScript functions in a website?

When integrating PHP and JavaScript functions in a website, it is important to properly handle the communication between the two languages. One common approach is to use AJAX to send requests from JavaScript to PHP, which processes the data and returns a response. This allows for dynamic and interactive functionality on the website. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])) {
    $data = $_POST['data'];

    // Process the data as needed

    // Return a response
    echo json_encode(['message' => 'Data processed successfully']);
}
?>
