Codeigniter

I have some experience with cakePHP and I eventually get to play with code igniter - another php framework and I think it's just too brilliant!

It's faster, flexible and much easier than cakePHP but the best part is their detailed guide, just about everything is in there. A codeigniter site is installed as soon as you copy and paste it and writing it's hello world program hardly takes 30 seconds. Learning it is not really a dedicated job, you could learn it on the go thanks to it's extremely well written guide.

Most of the helper functions like emails engine is already there and you don't really have to install any pear library. Unlike cakePHP it is much optimized, eg. it supports persistent db connection by default while cakePHP's default option is non persistent.

So if you are into php coding, this is one framework which you must check : http://codeigniter.com/downloads/
