The Farm mentions a new PHP framework: Symfony, which is described as the Ruby on Rails for PHP. I haven't actually played with it myself, but I did have a quick look at the ten minutes screencast and a ajax tutorial.
It seems fairly simple to me, although it's a shame that it needs to be installed on your server. That'll stop most people, including me, from actually being to use it on a production website. I'm on shared hosting, so I won't be able to install the framework. The same thing goes for Ruby on Rails.
It does boast a very extensive list of features, including:
- simple templating and helpers
- cache management
- multiple environments support
- deployment management
- smart URLs
- multilingual and I18N support
- object model and MVC separation
- Ajax support
which makes it even more of a shame that I can't run it on my web host. Check out the live demo as well, where you can use an app created with Symfony. Seems pretty neat, doesn't it?
