When the new PHP 5 behaviour was first being touted around, I remember it being explained that PHP 5 would use object _handles_ where PHP4 used the objects themselves. This is sort of analogous to (database) resource handles, or file handles, where what you get is a proxy for the actual thing. So Rob's statement would end up talking about a reference to a handle and a copy of a handle, which may help to make more sense out of what's going on! Cheers!
