<p>Who here is using WASP (<a href="http://wasp.sourceforge.net/content/" rel="nofollow noreferrer">http://wasp.sourceforge.net/content/</a>) to in real world applications? What impressions do you have? Good? Bad? If you can provide any inputs, how good it is comparing with rails for example.</p>

<p>I'm really looking for MVC frameworks for PHP</p>

I downloaded it a while ago and tried it out, but as the documentation is pretty terrible at the moment (consisting of some auto-generated 'documentation' that was useless) I gave up pretty quickly. I think one of the most important things to have in a framework is clear, thorough documentation - if you have to spend time digging through the code of the framework to find out if a class you want exists, the point of using a framework is lost. WASP does not seem to be ready for production environments just yet, as even their website admits that its not ready for enterprise applications.
If you're looking for a PHP framework I would recommend CodeIgniter, which has excellent documentation and a helpful community, or Zend, which is pretty mature.
