An overloading question

Show all headers | View raw

I have a problem that I am wrestling with that should be so obvious and 
easy -- but it isn't.  I have a base class that has a method that calls 
another method in the base class with $this->thatOtherMethod.  I have 
another class that extends the base class and I want to have 
thatOtherMethod in the extended class override the one in the base 
class.  The calling method in the base class is called using and 
instance of the extended class pointing to that method.

Simply, here is an example:

A.class.php
--------------------------
<?php
abstract class A {
     public function b() {
         $this->a();
     }
     protected function a() {
         print 'In class A';
     }
}
?>

B.class.php
---------------------------
<?php
include_once 'A.class.php';
class B extends A {
     public function a() {
         print 'In class B';
     }
}
?>

c.php
----------------------------
<?php
    include 'B.class.php';
   $x = new B();
   $x->b();
?>
----------------------------

I want it to print out "In class B", but it prints out "In class A".

I have looked over Google quite a bit and found nothing that helped.  I 
have tried making the methods public, protected, keep them both the same 
access, etc. and have had no luck.  Suggestions?
