I would like to get some good training on how to publish and consume web services using PHP. My employer is allowing me a budget to do this for next year. I was wondering if anyone new of some good web service training using PHP as the tool to do so.
Edit: Just to clarify a little. I have been using PHP for about 4 years now and am fairly confident with it. I would like training on anything related to web services with PHP. I know how to make curl requests and parse the data. I even know how, in a general way, to publish data I have via XML and JSON. What I would like I guess it training on the standards currently being used.
