How to connect flex4 with Symfony 2 for AMF calls


I have to use flex 4 for the front end and php with Symfony 2 as backend. I want to use amf to call remote methods on the php. I have known that Symfony 2 does not have plugin for amf communications with Flex. In this case how can I connect them? or I have to use httpservice/webservices which is slow in performance.

You can use AMFBundle, which has what you need.
