I guess you are wondering why isn't throwing an error
because you have 4 mandatory arguments in
User::notify(), right?
Hmmm, it makes sense what you're saying, because if I
would use your class and only know you're implementing
SplSubject, I'd knew there's notify() that I can use,
but as you have 4 mandatory parameters that would
throw 4 warnings.
I'm curious what other, more experienced PHP
developers have to say about this. I'm using PHP 5.2.5
too
