Oop

[berliner_kindl]

I have a shopping cart that is written oldschool (procedural) style PHP and I am trying to convert it to OOP PHP and learning as I go. Anyone interested in giving me a few pointers?

For example:

<?php

class Pagination {

	var $numrows;
	var $rowsperpage;
	var $totalpages;

        function SetPagination () {

	$this->numrows = 50;
        $this->rowsperpage = 12;   
        $this->totalpages = ceil($this->numrows / $this->rowsperpage); 
   }

}

?>

<?php
	 $page = new Pagination();
	 $page->SetPagination();

	 echo "numrows: " . $page->numrows . "<br />";
         echo "rowsperpage: " . $page->rowsperpage . "<br />";
	 echo "totalrows: " . $page->totalrows;
    ?>

why does $totalrows echo null?

I learned php oop from the book :

PHP 5 Advanced: Visual QuickPro Guide (Paperback)
by Larry Ullman

Very awesome book, and Larry has a forum where he is very active if you have questions.
