What are some best practices for integrating PHP and JavaScript to create interactive features like dropdown menus?

To create interactive features like dropdown menus using PHP and JavaScript, one best practice is to use AJAX to dynamically load content without refreshing the page. This allows for a smoother user experience and helps keep the code organized. Additionally, separating the PHP logic for fetching data from the database and the JavaScript logic for handling user interactions can make the code easier to maintain. 

<?php
// PHP code to fetch dropdown menu options from the database
$options = array("Option 1", "Option 2", "Option 3");

// Output the options as a JSON object
echo json_encode($options);
?>
