NYCPHP Meetup

[Jeff Knight]

You are the one that must be high to not see it... trying to eat your
cake and have it too. You're trying to be slick, sneak around the gate
and get away with something. The ultimate fact of the matter is that
you cannot access the contents of the $StaticMethod  property
("SayHello"), without instantiating the object. It does not matter
that you are then trying to do a perfectly legal operation with that
information, but that you do not have access to that information in
the first place.
