Lowell, The "->" operator was taken from the pointer operator in C. It's used to access a method or variable within an INSTANCE of an object, as opposed to the "::" operator, which is used to access a static method of a class. Note the difference between a class and an object -- an object is an instance of a class.
if Run() is a static method (I.E. it has no references to "$this") and "$site" is an instance of "SiteClass", the following are equivalent: $site->Run(); SiteClass::Run(); If you're still confused, I can go further into the difference between an Object and a Class. -- Sincerely, A.J.
