Is there a way to couple 'PARENT' to the specific class, such as $this->PARENT::Function();

example:
Object B extends Object A
Object C accesses Object B through $GLOBAL

Object B's PARENT::FUNCTION() now tries to access Object C's parent - whereas I want it to access object B's parent.

This works:

<?php
class A
{
   public function example()
   {
      echo "This is class A.";
   }
}

class B extends A
{
   public function example()
   {
      parent::example();
   }
}

class C
{
   public function example()
   {
      $GLOBALS['b']->example();
   }
}

$GLOBALS['b'] = new B();
$c = new C();
$c->example(); // outputs "This is class A."
?>

However, it is rather contrary to the philosophy and goals of OOP, in that depending on a global value creates a strong coupling between objects, when loose coupling should be your goal.

Perhaps you should look into making class B a singleton pattern, then get an instance of it within class C?
