What are the implications of renaming HTML files to PHP files without making any actual changes to the code?

Renaming HTML files to PHP files without making any actual changes to the code can lead to confusion and potential issues. This is because PHP files are meant to contain server-side code, while HTML files are typically static content. If the PHP file is not utilizing any PHP code, it may still be parsed by the server as PHP, potentially causing unexpected behavior. To address this issue, it is important to either remove the PHP extension or ensure that the file contains valid PHP code.

<?php
// Ensure that the PHP file contains valid PHP code
// For example, you can add a simple PHP statement like below
echo "Hello, World!";
?>
