Duplicating a class - php

Question

I am currently using a pagination script that uses a class named "pagination". I would like to duplicate this class in another file to use it again. I'm having problems with my framework recognizing it as "duplicate". I know that changing it should be as simple as changing the class name, but there are several functions within the class that makes it too complex for me to figure out.
So my question is, based on the code below, what variables, functions, values, etc. would I need to change in my class in order to create an identical copy of it?
class pagination {
/*
Script Name: *Digg Style Paginator Class
Script URI: http://www.mis-algoritmos.com/2007/05/27/digg-style-pagination-class/
Description: Class in PHP that allows to use a pagination like a digg or sabrosus style.

Try to include the file which holds the pagination class only once!
Use incldue_once or require_once instead of include and require.
