Zend_Json_Server – JSON-RPC server might do what you are looking for:

It supports both the » JSON-RPC version 1 specification as well as the » version 2 specification; additionally, it provides a PHP implementation of the » Service Mapping Description (SMD) specification for providing service metadata to service consumers.

Apart from that, there is also Zend_JSON, that

provides convenience methods for serializing native PHP to JSON and decoding JSON to native PHP. […] In addition, Zend_Json provides a useful way to convert any arbitrary XML formatted string into a JSON formatted string. This built-in feature will enable PHP developers to transform the enterprise data encoded in XML format into JSON format before sending it to browser-based Ajax client applications.
