title: A good PHP framework that is also scalable?
body: <p>I'm already into PHP and now I'm going to learn a new framework, because I am going to build a web platform that will be used by millions. So this obviously means I will need to scale it at some point of time and so with SO many options around me I'm just plain confused :| I read some articles on the web and I've come to a conclusion that Cake PHP and Symfony are good frameworks and are used by huge corporations. However, I am a little sceptical about the scaling part of these frameworks since I will be using AWS instances to host my project and it should be quite easy to scale. Thank You.</p>
