# Introduction

`Zend_Amf` provides support for Adobe's Action Message Format (AMF), to allow communication between Adobe's Flash Player and PHP. Specifically, it provides a gateway server implementation for handling requests sent from the Flash Player to the server and mapping these requests to object and class methods and arbitrary callbacks.

The AMF3 specification is freely available, and serves as a reference for what types of messages may be sent between the Flash Player and server.
