Accessing a protected method from a parent class

I understand that I should make a method "protected" when I want it to be only available to all classes that extend the current class as well as the current class.

Okay, grandChildClass::method2() should be protected since grandchild is extended from child.

But what should it be if accessed from a parent class such as parentClass::method2()?

class parentClass
{
    public function method1() {$this->method2();}
}

class childClass extends parentClass
{
    protected function method2() {}
}

class grandChildClass extends childClass 
{
    public function method3() {$this->method2();}
}

If you try to

$p = new parentClass;
$p->method1();

You'd get a fatal error for undefined method.

Fatal error: Call to undefined method parentClass::method2() in ... on line ...

However, this will work fine:

$c = new childClass;
$c->method1();

$g = new grandChildClass;
$g->method1();
$g->method3();

All of these will call method2 as defined on childClass.
