<p style="margin: 0px;">OK, now I understand what you're doing.</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">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.</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">Here's a simple example:</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">include_once(ABSPATH . WPINC . '/class-IXR.php');</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">$client = new IXR_Client('destinantion_url');</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">$client->query('procedure.name', 'arg1', 'arg2', 'arg3', ...);</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">$response = $client->getResponse();</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">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.</p>
<p style="margin: 0px;"> </p>
<p> </p>
