Show and Run queries as a user

You can use the wpdb class which handles all communication with MySQL.

I have to be missing something pretty basic. Whenever I try to call that class, it’s not returning the query, it’s just viewing the code as text.

I’m trying to run three different versions here: https://matails1.synology.me/wordpress/ but as you can see they all just show up as text.

What am I missing?
