How can one make PHP files executable on their local machine?

To make PHP files executable on a local machine, you can install a local server environment like XAMPP or MAMP which includes PHP support. Once the server is set up, you can place your PHP files in the server's designated folder (e.g., htdocs for XAMPP) and access them through a web browser using localhost.

<?php
// Sample PHP code snippet
echo "Hello, World!";
?>
