As the PHP Web Services blog points out today, there's some training offered for developers looking to get into working with web services (using SOAP and WS-Security specifically).

Here's the description of the course

This training helps you create secure Web services and clients using SOAP, and WS-Security, which are inter-operable with Java and .NET systems. It also teaches you how to work with WSDL and binary attachments when using Web services in PHP.

The class lasts for three hours and requires that you have some level of experience with web services (enough to know XML and the concepts behind passing it as messages back and forth). The cost for the event is $199 USD and the next session for it is coming up on January 16th starting at 9am (PST). You can get additional details on it from the detail page on the wso2.com website.
