Okay.  Here's part of the problem.  You're looking at PHP's functions that
manipulate classes.  You need to be looking at the "language reference"
section that explains how to write your own objects and utilize them.

Manual:
   http://us2.php.net/manual/en/index.php

Section II:  Language Reference
   Subsection 13:  Classes and Objects
     http://us2.php.net/manual/en/language.oop.php

Read the text there then copy the example.

Then, since you're interested in extensions of classes, click the link on 
the top of the chapter named "extends."

Read that information.  Copy the examples into the same file as the other 
example.  In there is this line, that answers your question of how to 
access a method from the original class:

   $ncart->add_item("10", 1);  // (inherited functionality from cart)

That's how you call ANYTHING from any part of the class when you're in PHP 
code that's not part of a class.

Execute the example to see what it does.

Which is how you call a method of the the class (be it a parent, child or
itself) from _inside_ any method of the class regardless of whether you're
in the parent, child or present class.

If you posted these URI's up front, we could have told you up front that 
you were looking in the wrong places and point you to the right place.
