I agree in parts. Things "doesn't mean its should necessarlly" is very very relative. If we think in this way, like PHP is a simple language (but very powerfull) we doesn't have to use OOP to build one application, for example. We need to think carefully about the life time of the application. Mainly when we are talking about frameworks. Watch the evolution walking aside is very important. Another point, talking about frameworks, extending some feature in some times is necessary. Doing in PHP4 using OOP to do this is extend a real class that works like astract class, but there is no interface class, its would be hard to provide reliability. What can do in PHP5. Altough, I agree with you we don't need to implement all new features, but, we need to be carefull with what features evolved. Again, "It's works" isn't a good reason. Mainly in this case. >> "It's Works" don't seem to me one good reason to not do evolution. >> Mainly when some concepts are deprecated. >> >> I'm don't talking that CI is not good or enough, just, I offer IMHO >> some interesting questions. > > I don't know how CI works, just that I also maintain backward > compatibility for my framework to PHP4.
