Is it recommended to use PHP and JavaScript together in a single document?

It is not recommended to mix PHP and JavaScript in a single document as it can lead to confusion and make the code harder to maintain. It is better to keep server-side PHP code separate from client-side JavaScript code for better organization and readability. To solve this issue, you can use AJAX to make asynchronous requests to the server and retrieve data without mixing PHP and JavaScript in the same document. 

<?php
// PHP code
$data = array("message" => "Hello, World!");
echo json_encode($data);
?>
