Being a web development over the years, I have good experiences on php, xhtml, css, javascript, ajax, etc. I also work with some old php libraries like Smarty, PEAR, etc. Recently I decided to use a PHP framework, and I started to learn/use CakePHP. It's not really simple for an ancient philosopher like me, but I think it's a valuable experience.
Now I'm planning to select a good framework, because I haven't enough time to learn many new things like the past years. Searching on StackOverflow I found the Kohana framework and it seems to be a good framework. Would anyone please let me know if it's a good idea to switch to Kohana when I'm (a little) familiar with CakePHP. Witch on is better and let lazy developers like me be aware from switching to another framework in the future?
Thanks for your help
