2. 7.2 connections/clients_drupal/clients_drupal.inc \clients_connection_drupal_services_5::callMethodArray()

Call a remote method with an array of parameters.

TODO: REFACTOR this to look more like the static methods above -- separate methods for getuser, connect, etc etc.

Parameters

$method: The name of the remote method to call.

All other parameters are passed to the remote method.: Note that the D5 version of Services does not seem to respect optional parameters; you should pass in defaults (eg an empty string or 0) instead of omitting a parameter.

Return value

Whatever is returned from the remote site.
