What are some best practices for integrating PHP and JavaScript in a web development project?

One best practice for integrating PHP and JavaScript in a web development project is to use AJAX to communicate between the two languages without refreshing the page. This allows for dynamic and interactive user experiences. Another best practice is to separate PHP logic from JavaScript code to maintain a clean and organized codebase. Additionally, using JSON for data interchange between PHP and JavaScript can simplify data handling and processing. 

// PHP code to handle AJAX request and return JSON response
<?php
// Assuming this is ajax-request.php
$data = array("message" => "Hello, world!");
echo json_encode($data);
?>
