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!
