First, the SQL table did not display
Second, the compiler didn't find the included files. Please tell me how I should do it.
The included files are an example, you'd use your own files for connecting to your database.
This is code for implementing into your own existing code, and i think it makes the assumption you are doing the other necessary parts such as connecting to the database.
Looks straight-forward enough to me, thanks again author person (admin).
