Object persistence

I have been experimenting a bit with trying to register and pass objects
from one page to the next.  PHP's support for this appears to be quite
limited and possibly fickle.  My search throught the mail archives reveals
similiar gripes about its lack of support in this area.

It could be that I just don't know the proper way to pass such objects.  I
would like to know, however, if other people have run into similiar
difficulties and if there is a "best practices" way of doing this.

Assuming that there are limitations to PHP's current support for object
persistence, I am wondering if session management for objects is something
that should be / is going to be implemented at a language level or whether
it should be implemented as a PEAR object persistence class of some sort?
