alright, get ready for a ton of flamage here after i'm done...
first, to be correct and accurate...objects are passed to functions by
reference, objects in arrays are by reference (i.e. when using foreach),
etc., etc.. variable assignment is by value. while $b = &$foo behaves like a
pointer in *every* way, in php there are no true c-style pointers. $b is
just an alias for $foo, a nickname...because of the amphersand (&). make
sense?
