This module is EXPERIMENTAL. That means that the behaviour of these functions, these function names, in concreto ANYTHING documented here can change in a future release of this package WITHOUT NOTICE. Be warned, and use this module at your own risk.
Satellite is deprecated. It is suggested that you use Universe (http://universe-phpext.sourceforge.net/) and not Satellite.
The Satellite extension is used for accessing CORBA objects. You will need to set the idl_directory= entry in php.ini to a path where you store all IDL files you use.
See the Satellite README file for details about installing Satellite.
