What are the potential pitfalls of trying to execute PHP code without a server that can interpret it?

Executing PHP code without a server that can interpret it can lead to the code being displayed as plain text in the browser instead of being executed. To solve this issue, you can use an online PHP sandbox or install a local server like XAMPP or WampServer on your machine to run PHP scripts.

<?php
// Your PHP code here
echo "Hello, World!";
?>
