What are the potential challenges and considerations when deploying a browser game developed with PHP on a server rather than running it locally on a personal computer?

One potential challenge when deploying a browser game developed with PHP on a server is ensuring that the server environment is properly configured to support PHP scripts. This includes setting up a web server like Apache or Nginx, installing PHP, and configuring the server to execute PHP scripts. Additionally, you may need to consider security measures such as protecting sensitive data and preventing unauthorized access to your game.

<?php
// Sample PHP code for setting up a basic PHP script on a server
echo "Hello, world!";
