php - could static members use nonstatic members and vice versa?

Question

could i use nonstatic members inside a static method?

eg.

 $this->nonStaticProperty
 $this->nonStaticMethod()

and vice versa that is to say use static members inside non-static methods?

Answer 1

As a static member doesn't have an instance, it can't call instance methods (unless you create an instance inside that method).
