PHP classes

[Anon]

I got a question about implementing a PHP class.

I'm really new to PHP and my background is in C++ coding. My question is, with PHP classes, once I move to another page, don't we lose all the variable values (unless we use a cookie or push them through the URL, etc.)
For example, let's say I have a shopping cart. Someone can add items to their cart on various pages. I don't want to declare a new instance of the shopping cart class each time because I want a cumulative total. So, how do I implement a class across many pages. I'm thinking I should use "include("myclass.inc")" on all relevant pages.

Is this correct?
Thanks,
M

Yes, welcome to the world of static programming; it was one of the toughest things to learn and get used to as far as switching over; and quite simply, it sucks, and is one of the big reasons why I'll always perfer conventional programming. 🙂 But yes, if you change a page via a link or form submission you will have to include your class again.

Register the variables as session variables which become global variables during each browser session

see session_register ()
