When did you get into Codeigniter?

i worked mainly with CMSs, namely Joomla and later Wordpress. Did a couple of things for e-commerce too. Lots of payment integrations for a score of platforms. Then i had to do work on a pure-PHP website. And a complicated one. The code was already messy to start with and it became worse as you extended it. A ton of files, all very confusing and hard to maintain. Then i said to myself: i need a framework. Codeigniter won me over the documentation. Been using it for over two years now.
