How come the Drupal XML RPC API doesn't use any of the PHP XML RPC functions defined here: http://php.net/xmlrpc ? Is this a completely different implementation? Why? Is there a historical/technical reason behind this?
Well it's an extension and we can't depend on it being installed on most servers. That and the warning on the PHP site says it all: "This extension is EXPERIMENTAL. The behaviour of this extension -- including the names of its functions and anything else documented about this extension -- may change without notice in a future release of PHP. Use this extension at your own risk."
How does a XML RPC "session" happen?
As far as I know it's state-less, if you want sessions you'll need to write those.
I.e., if I have a drupal XML RPC client module, that needs to contact a remote XML RPC server, do I get a chance to send the call, get the reply and process that reply all within one page load, as if it were a SQL query?
Yes, it's just a function call.
What modules exist that use XML RPC a lot, that I could study?
How would a simple code snippet look like? (make a call to server, get reply, and have a if / else fork according to the reply we got - or display / print_r() the content of the reply).
I've done a bit with XML RPC in the station module. The archive and schedule sub-modules are desinged to run on different machines and grab program information remotely. The code is sort of scattered around but it's a working example. andrew
