What are the challenges of previewing a PHP file in an editor compared to an HTML file?

Previewing a PHP file in an editor can be challenging because PHP code needs to be executed on a server with a PHP interpreter, unlike HTML files which can be directly rendered in a browser. To solve this issue, you can set up a local server environment like XAMPP or WAMP on your machine to run PHP files locally.

<?php
// Your PHP code here
?>
