XML-RPC Custom Hooks Request I have developed my own xmlrpc hook, which have certain functions.

Basically I need to call that functions outside Drupal. So I can't use xmlrpc() function.

What is most simple method to call that functions through Drupal's xmlrpc.php?
PHP has an extension for XML-RPC, but it's not enabled by default. If your PHP installation doesn't have the extension, you can use one of the PHP libraries that handle XML-RPC requests, such as XML-RPC for PHP, and The Incutio XML-RPC Library for PHP; if you have downloaded the Zend Framework, you can use its XML-RPC classes.
