- * XML_RPC2_Server is the frontend class for exposing PHP functions via XML-RPC.
- *
- * Exporting a programatic interface via XML-RPC using XML_RPC2 is exceedingly easy:
- *
- * The first step is to assemble all methods you wish to export into a class. You may either
- * create a (abstract) class with exportable methods as static, or use an existing instance
- * of an object.
- *
- * You'll then need to document the methods using PHPDocumentor tags. XML_RPC2 will use the
- * documentation for server introspection. You'll get something like this:
- *
- * <code>
- * class ExampleServer {
- * /**
- * * hello says hello
- * *
- * * @param string Name
- * * @return string Greetings
- * {@*}
- * public static function hello($name)
- {
- * return "Hello $name";
- * }
- * }
- * </code>
- *
- * Now, instantiate the server, using the Factory method to select a backend and a call handler for you:
- * <code>
- * require_once 'XML/RPC2/Server.php';
- * $server = XML_RPC2_Server::create('ExampleServer');
- * $server->handleCall();
- * </code>
- *
- * This will create a server exporting all of the 'ExampleServer' class' methods. If you wish to export
- * instance methods as well, pass an object instance to the factory instead:
- * <code>
- * require_once 'XML/RPC2/Server.php';
- * $server = XML_RPC2_Server::create(new ExampleServer());
- * $server->handleCall();
- * </code>
