[development] takeover variables from session to 3rd party scripts

[Stefan Pampel]

i want to integrate a php script via module and want to take over some
variables from module

        function foo_settings()

into the other script. Some hints how to take over the settings?
Tried some $_SESSION['foo_var'] stuff but dont work.

        echo session_id();

gives the same session_id

thx
