PHP: how to call a method from a parent class that we have overridden?

Question

PHP

Let's say we have a parent class:

class ParentClass {   
   protected $field;   
   public function showField() {
      print($field);   
   }
}

And there is a child class:

class ChildClass extends ParentClass {
   public function showField() {
      /* ... code ... */   
      /* Вызов метода showField() из родительского класса */
      /* ... code ... */
   }
}

The question itself is: how to call the showField method from the parent class ParentClass in the child class ChildClass ?

Answer 1

Use language construct
parent::showField();

Answer 2

Create an instance of the parent class?

Answer 3

Could be so,$this->showField();
