php-jsonrpc2

A simple yet robust PHP JSON-RPC 2.0 Client and Server implementation supporting both method and class.method method calls

Features

Robust and easily extensible JSON-RPC 2 compliant server, drop-in and it's ready to use.
- Immediately if you have an autoloader or pre-include all your API method classes.
- Easy to implement your existing session or API key code (with examples)
Simple as hell JSON-RPC 2 client code, start consuming JSON-RPC services immediately (with local and remote examples)
- Method chaining and/or dynamic method execution
- Setting Top-level arguments (for api keys/sessions/etc)
- Adding HTTP Headers (for api keys/sessions/etc)
- Supports JSON-RPC 2.0 By-Name (keyed) Parameters in both chained and dynamic method execution (with examples)

Write some/better tutorials/example classes! So more people can easily start using this class!
Write some unit tests, to ensure the classes integrity as they (potentially) grow
Implement bi-directional JSON-RPC to facilitate a persistent connection from a client to a server (eg: for a flash game or chat client)
Allow the bi-directional server mechanism to work asynchronously and non-blocking by launching threads (or something, if possible) to handle each incoming request on a stream
Finish and github my JSON-RPC 2.0 web-based consumption/testing code which is a simple visual tool to consume and test your services

Run the sample.php script via a webserver and see how it works, and what it does. It will walk you through all the things that the library handles including the (new) client library and the server library
Then try pointing some of your client code against the endpoint at sample_endpoint.php by pointing your code to http://yoursite/php-jsonrpc2/sample_endpoint.php
Then go create your own JSON-RPC 2.0 server or client and share your experiences with me! Submit patches, add unit tests, document something, or just tell me how cool open source software is.
