Help
i'm starting using yii, and i don't understand where should be the new classes, my questions are:
how can i distinguish when a class is component, extencion, aplication component or widget?
what should (messages, migrations, runtime, data) folders contain?
if i'm using a folder with no OO php files and i create a class for use them... where should i put my class, and where the folder with the files?
sorry the language... using translator... but not trusting totally
