How can a beginner ensure that a PHP server is set up correctly to run smoothly?

To ensure a PHP server is set up correctly to run smoothly, beginners should make sure they have installed PHP, a web server (such as Apache or Nginx), and a database (such as MySQL). They should also configure their server correctly by setting up the necessary PHP settings and permissions. Finally, beginners should test their PHP scripts to ensure they are executing properly.

<?php
// Sample PHP script to test server setup
echo "Hello, PHP!";
?>
