Currently I noticed about kohana. It is a CodeIgniter’s(CI) fork. It seems handy to me. It have extra module for support like authentication, GMap, E-commerce etc. The main thing attracted me is its ORM support. And another reason is its support for loadingany library or model automatically.
Here is an example to load a library named Calender:-
For kohana the statments are:
$calender = new Calender;
ORM is another important difference with CI and Kohana. Hope everyone will like kohana.
