So, I have worked well with YII 1.* and all was good. The basic template of YII2 doesn’t have that much difference from YII 1. However I decided to use the advanced template, then I found that there was \frontend and \backend.
Problem is, they have almost the same directory structure, which isn’t a problem at all. sooo…if i am going to write my controllers, and model and views in \backend, but these are the same controllers and models that product users will access, do i have to manually copy them back to \frontend when that time comes to go to production mode?
