PHP XML-RPC Client

Well there seems to be a lack of simple examples or documentation on connecting a PHP XML-RPC client to Drupal Services. If this example exists, I could not find it.

Here is my example code:

Please comment on it, if you have suggestions.

I wonder if this should be on the Example page in the handbook?
