Spring ActionScript

Spring ActionScript is an application framework for ActionScript 3.0 and is an offshoot of the Java Spring framework. It contains an Inversion of Control (IoC) Container for managing objects and components in a non-intrusive way. The container can be configured using XML, MXML or metadata/annotations.

Further, the framework also contains base classes for setting up a Model-View-Controller architecture for your application, utility classes for configuring and extending Cairngorm and PureMVC applications, and many other interesting utilities.

AMFPHP

AMFPHP is a free open-source PHP implementation of the Action Message Format(AMF). AMF allows for binary serialization of Action Script (AS2, AS3) native types and objects to be sent to server side services. AMFPHP is challenged with implementing the entire AMF protocol to be an alternative to Flex Data Services (AMF3) and Flash Remoting (AMF0). AMFPHP allows thin client applications built in languages such as Flash, Flex, and AIR to communicate directly with PHP class objects on the server.
