I have been doing PHP for many many years, however recently I read a book on Ruby on Rails and was very impressed, it makes PHP look like a toy language (hopefully that does not offend anyone?!?!?! - but its true).

Now I am considering advancing my Ruby on Rails skills more, resulting in my next project in a few months being built with RoR. This is a big change and would require a lot of time and hard work.

Has anyone else considered changing to RoR or any other language?

NB: RoR equivalent would be Zend Framework.
