I have been looking into a lot of slim example projects on GitHub, and i see both folders being used.
And i don’t get to understand what the differences should be.
In my opinion the src folder should be used to add commonly used files like base classes etc.
And the app folder is mend for the working controllers/models/routers etc.
Sadly in most cases i dont see that break-up of logic.
Before i start creating my own i love to know what are you troughs about this?
