session_set_save_handler() sets the user-level session storage functions which are used for storing and retrieving data associated with a session. this is most useful when a storage method other than those supplied by php sessions is preferred. i.e. storing the session data in a local database.
the proccess of aggregation is cummulative, so when we aggregate $fs with the class dbstorage, generating an object that can use the storage methods of all the defined classes.
we then aggregate $fs with the wddxstorage class, and print out the object information. we can see now that even though nominally the $fs object is still of filestorage, it now has the property $version, and the method store(), both defined in wddxstorage. one important thing to note is that it has not aggregated the private elements defined in the class, which are present in the $ws object. also absent is the constructor from wddxstorage, which will not be logical to aggegate.
