Good Login Sample

Does anyone have or know where to find a good example of a login using a database to get access name and passwords then using cookies? I have thought of a couple ways to do it but I want to make sure I'm not creating security risks and I also want to make sure every page on the site is protected. Yes I can do it with an .htaccess file but I would rather do it in a webpage then allow the user to have a cookie saved to remember their account. I don't need the full thing done for me, Id just like to have something to start with. The existing login scripts I have found have been insufficient for what I want to do. They are either just a regular login that checks a database and doesn't check every page to make sure the user is logged in and is a correct user or they don't allow for saving the information to access the site. If anyone can help it would be greatly appreciated. Chris Noble
