sorry to be asking so many stupid questions in one day (but the documentation doesn’t seem to cover simple things too good)
what class in yii is responsible for string formatting?
is there even such a class?
for example i want to do the very common
str_to_lower, but i want to do it while supporting UTF8, so i need to add this custom function to some class in yii, which one? or do i create a separate application component? or how do you handle this simple thing with custom functions anyway?
