There used to be a PHP setup parameter that controlled the expiration of the session cookie on the browser, and I have on occasion set that up to live well beyond closing the browser (which opened a couple more of Pandora's boxes, when I had multiple browsers pointing to the site, but you should be able to retain things for quite some time). The user can override all this by clearing cache on the browser which is as it should be, but one thing to remember is that most browsers cache cookies and such by domain name and there are parameters that can give them a "life of their own" so to speak. I had users who shut down their browsers and returned the next day to have their session data remain.
