#codeigniter cart

I'm new to CodeIgniter and I am learning about the cart class right now. It is crazy how there is a class like this built into CodeIgniter! Past the initial amazement, I suppose Django and Ruby on Rails are just as crazy - if there isn't a cart class built-in, there are probably dozens of classes that other programmers have created for facilitating coding like this.

It is so simple to use!
