Say I have a parent class
class parentClass {
public function myMethod() {
echo \"parent - myMethod was called.\";
}
}
and
In this case it makes no difference. It does make a difference if both the parent and child class implement myMethod. In this case, $this->myMethod() calls the implementation of the current class, while parent::myMethod() explicitly calls the parent's implementation of the method. parent:: is a special syntax for this special kind of call, it has nothing to do with static calls. It's arguably ugly and/or confusing.
