When did you get into Codeigniter?

I started learning CodeIgniter about a week ago. I'm trying to build an online marketplace where users can sell products as easily as possible.

I started a month or two ago using just PHP, but I realized the need for a framework to speed up the development.

I decided to use CodeIgniter because a lot of people's claims that it is one of the easiest frameworks to set up and learn.

I find it difficult enough, but I'm optimistic.
