Re: [PHP4BETA] Session Variables in classes

Session variables are suberglobals, an extension of the concept of the global variable. Globals are variables with a lifetime of the entire run and a visibility throughout the whole program. Session variables extend this concept by creating variables with a lifetime over multiple runs of the same program and a visibility throughout multiple runs of that program. Saving a single member variable of an object is semantially useless, because such a member variable would be pretty much useless without the surrounding object. It is a component of a compound type and saving only a single member in a session would result in an incomplete type. Saving an object, but not keeping the values of all member variables or - alternatively - creating pre-save and post-load wrapper functions which may prepare an object for cold storage and thaw it afterwards are another thing and have been discussed on this list just a few days ago (but I do not remember what the decision was).
