Hi there,
A few things to note: First, codepen is not the best for php. Codepen is more for front-end development, PHP is a server-side language so in order for you to see your code work, you would have run an Apache server, via Xampp for Windows, or Lampp for Linux.. or get a hosting service that allows you to use php. Second, due to above reason, you are exposing your database queries, which is very bad in terms of security.
