It seems like you call parent on a different method (getNext() instead of current()). Are you sure this is correct? If so, you might want to change this to $this->getNext().
                                                                                                                                                                                                        

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for a call to a parent method whose name is different than
the method from which it is called.


Consider the following code:


class Daddy
{
    protected function getFirstName()
    {
        return "Eidur";
    }

    protected function getSurName()
    {
        return "Gudjohnsen";
    }
}

class Son
{
    public function getFirstName()
    {
        return parent::getSurname();
    }
}





The getFirstName() method in the Son calls the wrong method in the
parent class.

It seems like you call parent on a different method (hasNext() instead of valid()). Are you sure this is correct? If so, you might want to change this to $this->hasNext().
                                                                                                                                                                                                        

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for a call to a parent method whose name is different than
the method from which it is called.


Consider the following code:


class Daddy
{
    protected function getFirstName()
    {
        return "Eidur";
    }

    protected function getSurName()
    {
        return "Gudjohnsen";
    }
}

class Son
{
    public function getFirstName()
    {
        return parent::getSurname();
    }
}





The getFirstName() method in the Son calls the wrong method in the
parent class.
