ClassName::staticMethod()
calls the *static* method "staticMethod" in ClassName.
:: is the operator the access static methods.
Static methods can be called without having an object of the concerning
class. Therefore static methods (actually a function a class) may not
use "$this".
$object->method() calls the method "method" of the object referenced by
"$object". Non-static methods work with the state of the object they
belong to.
If you still do not know the difference between static and non-static
methods you should consult some OOP-explaining websites or books.
