[wp-xmlrpc] PHP Library

[eric at eamann.com]

OK, now I understand what you're doing.
 
When I first started working with WordPress and XMLRPC, I tried building my own
library ... it was taking a long time, and I ran into many of the issues you're
running in to now.  Someone suggested I use the built-in IXR library instead,
and it made all the difference.
 
Here's a simple example:
 
include_once(ABSPATH . WPINC . '/class-IXR.php');
 
$client = new IXR_Client('destinantion_url');
 
$client->query('procedure.name', 'arg1', 'arg2', 'arg3', ...);
 
$response = $client->getResponse();
 
That will load the library, create a new client pointing at whatever WP
installation you're working with, execute your remote procedure, and store the
response (errors, data, or whatever) in the $response variable.
