Thanks for the response Ken. Sorry, guess I wasn't too clear about my
question, part of my question is also about the lifecycle of the XML-RPC
server. Your response was rather generic in terms of PHP and not XML-RPC
"server" via PHP.

With other languages where the HTTP server is bundled/built into the
XML-RPC server, the lifecycle is you start up server, that's the instance
of the server and it ends when you shut down the server. During its
lifecycle/operation, all requests to the server go through the same XML-RPC
server instance.

>From your response and a re-looking at the code, I'm using these as
reference

http://phpxmlrpc.sourceforge.net/server.php?showSource=TRUE
PHP XML-RPC server doc: http://phpxmlrpc.sourceforge.net/doc-2/ch07s05.html

It appears the lifecycle is the "XML-RPC server" is initialized on an HTTP
request to any PHP page that invokes the "XML-RPC server" (whether directly
in the page code or via code in include file), and that the server sorta
stops after it completes the HTTP response back to the requesting client?
Because otherwise, the PHP module on the HTTP server would keep spawning
XML-RPC server instances if its lifecycle didn't end with the response
being sent back (memory leak, etc.), unless of course the PHP module knew
to reuse the server on subsequent requests.
