Here is the server script. It's named xmlrpc.php and located in the document root of the web server at localhost:

The XML_RPC_encode() function automatically converts PHP data into the format needed by the XML_RPC library.
<?php
require_once 'XML/RPC.php';
$data = fetch_row_from_db(); // Hypothetical example.
$params = array(XML_RPC_encode($data));
$msg = new XML_RPC_Message('some_function_name', $params);
$cli = new XML_RPC_Client('/xmlrpc.php', 'pear.php.net');
$resp = $cli->send($msg);
// Process the same way as the other examples...
?>
