how to write web services using cakephp

Is it possible to write web services in CakePHP? any sample tuto开发者_高级运维rial?

Webservices are not really different from normal web applications. The main difference is the output.

Because you don't tell what kind of service you want to build, I only can give general advice.

Yes, just format the output as XML or JSON or something else instead of HTML.
