What are the security implications of attempting to emulate PHP functions on a web server that only supports HTML files?

Attempting to emulate PHP functions on a web server that only supports HTML files can lead to security vulnerabilities as the server may not have the necessary security measures in place to handle PHP code. To solve this issue, it is recommended to use a server that supports PHP or to refactor the code to only use HTML and client-side JavaScript for functionality.

<?php
// This code snippet is an example of how to refactor PHP code to use client-side JavaScript instead
echo "<script>alert('Hello, World!');</script>";
?>
