According to Yahoo Biz, a company called WSO2 released their WSO2 WSF Framework C-library. What is more appealing is that there are now bindings for PHP available under a Apache 2.0 license. The company WSO2 describes itself as: "We are thought leaders in the Apache Web service project, where our engineers are core contributors to key projects including Apache Axis2, Apache Sandesha, Apache Rampart, Apache Neethi, Apache Axiom and Apache Synapse."

The framework provdes a set of resources that can be used to quickly create web services for your application. It also features interoperability with .NET and J2EE implementations.

The ThinkPHP post even helps you take the first steps by providing a step-by-step guide to installing the source and getting it up and running.

One of the Zend conference sessions that I'm pretty excited about is Don Samisa Abeysinghe's (of WSO2) "Fully Fletched Web Services with PHP".

I'll be presenting a session on "Moving to PHP5 with Style." This tutorial/case study will be based on experience in transitioning several codebases from PHP4 to PHP5, creating unit tests & started a move towards a service based architecture without a complete platform rewrite.

Aaron's talk fits under the banner of the "PHP Development" talks, including others on topics like hosting PHP applications on Windows, working with PDO, unicoding in PHP6, and using PHPUnit.
