I tried symfony only. It was a little tricky (also because there is no command line or ssh connection in my hosting plan) to rearrange directory and linking in order to work on my hosting service, I did the same tricks on the local version to make the deployment easy but sometimes (don't know if is a cache problem or what) there were different result from the same version running on the server and on my machine.
I'm not saying I gave up with symfony but I'd like to know if there is something better before continue learning symfony.
I'm using shared hosting, so I can't use python/asp/everything else :D
The question is just the one of the title: What is the best free PHP framework working on shared hosting and why?
