Yeah, I can change the `_` prefix to `.` if you want me to. The reason why I chose `_` over `.` was that none of the `*.ini` files would be "hidden" from users that are interested in the PHP settings (eg. while listing files using `ls` or `tree` commands without any extra options). I thought this would be more obvious if they want to fill a potential bug / for the code or something.

I don't understand this comment. Could you explain it, please?
