I am deciding to do all the new code/functionality to be done in CI 2. I am a complete noob in CI . What are the do and fonts that you recommend. Also what is the best way to call existing code with CI. Old code is just normal PHP with classes/functions at a few places.
Also let me know what all do i need to read before i begin.
In order to re-user your old code – use CI libraries. But please note that you might have to change a few things in your old code for it to work.

I’d strongly advise you to read through the whole (or atleast part of) CI manual/user guide.
You might want to read through this before beginning to work with CI. It has some good points.

And on a related note – you might want to read through the PHP manuals OOP section first. And perhaps google ‘MVC arhitecture’.
