Re: [PHP-SOAP-DEV] bug storing the SoapObject in session

I want persistent client object because I want to access a soap service and
to have a live session on the remote part between requests of client part.
So I do a site which uses SOAP remote service for authentication and SOAP
remote service for accounting the time a employee has spent in the office.
There are 2 classes -> CAuthenticate & CPresence in 2 files. When users logs
in into the system by using CAuthenticate a session is created and some
stuff about the user is stored there(caching). When an user wants to state
that it is in working time method CPresence::presence_login($comment) is
called, and all info about the user is gotten from the session but I can
keep the session_id only(as far as I know) with keeping SoapObject in client
part. There is a little hack(because of lack of private vars) - on the
client part I modificate $client->location & $client->uri to get it work
with another service. I've no such warning message on my box but this is
because the error_reporting level is set to something strange.
Hope that clears what I do.
Andrey
