there are many ways to do the cart in PHP.
You can use cookies to save the cart in the user computer, but you are restricted to 20 cookies per user, or use sessions and here you lost the cart as soon as the user closes the browser.

You can too use a database to save the shopping cart of a user, it's the most polite way to do the job, but you can have too much garbage in the database. You have to do a garbage collect, and here the decision is yours.

I thing there are too many scripts to help you out. Try and check in

Is there a session on end thing like ASP because I want to clear the database stuff out when session ends Regards

Yes, but you have a problem. If the user closes the window, the session will terminate by garbage collect. And in this way you cannot remove the data from the database.

What you can do, is recreate the sessions, creating all the functions, and when you are GC you remove the session and the junk in the DB. Anikin

I would do it as following. As long as the user shops, fill the session and do not write to the database. Only when the user confirms the order write all session data into the database. This will result in a clean database which is also usefull. mcvdmvs

Yes, but what would you do if, for example, the costumer computer crashes, or for example, lights out? The user loose the cart, and he have to start all again.

Use some GC. For example running once in 100 times, cleaning all records not changed in the last week.

This way, inform the user that the cart will be availble only for one week. Anikin
