We've just made the first release of the Service Component Architecture (SCA) for PHP prototype available.SCA allows you to turn PHP classes into Web services by adding a few simple phpDocumentor-style annotations.SCA will automatically generate WSDL for these services when required. SCA also uses the same annotations technique to allow PHP classes to declare dependencies on other Web services or PHP classes.At runtime it will then 'inject' proxies for these dependencies, which can then be used to call the Web services or classes
Documentation, download package and samples can be found here.A very short whitepaper, which goes through the main concepts of SCA is also available. Our goal is to make this properly open source in the next few weeks, so people can report bugs, submit patches and contribute.We have a phpsoa Google Group where people can discuss SCA and its 'sister' project, SDO.
If you get the chance to give SCA a try, and you have comments/feedback, good or bad, we'd love to hear from you. You can contact us via the Google Group, or via the email addresses for the maintainers of the SDO project.
