        echo '<br /> Destructor activated from class Test <br />';
    }
    
    public function setProperty($val)

        $this->pr = $val;
    }
    
    private function getProperty()

        return $this->pr;
    }
    private function f()

class MyNewClass extends Test
{
    public function __construct()
    {
        parent::__construct(); 
        echo 'Constructor activated from class MyNewClass <br />';
    }
    public function runProtectedMethod()
    {
        return $this->getProperty();
    }
}
 
   
$obj1 = new MyNewClass;

$obj1->setProperty("some value");
// private methos accessible only from 
// within the class that defines it: class Test 
echo $obj1->runProtectedMethod();
