I have a similar problem.

I wanted to read data directly from MySQL database. I have a password, user name, host, etc.? How to display such data in the panel or any strings? and may need to create any file in PHP, how he is look like?

I have only local database *.db but I'm not interested and it is not practical because as each user will read data from a database that is hosted on another and not with them on a local computer
