I just want to give you a simple example that for diff. of session and cookie is that--- When in our gmail account we will see that one option is there to save the password for 2 weeks, so that eans when u check that bbox and submit then one cookie is created for that comp. with your details nand the expiry time would be for 2 weeks (by converting insec.). And when u r in checking of your in box just copy the contents of address bar and then closs all the windo and again paste the address bar link it will sshow you the login page because your inforation is stored in seession.So when a page starts it first of al it check the session.it will check the session id from your co. which is not set when you logged out.... FOR SESSION == " A visitor accessing your web site is assigned an unique id, the so-called session id. The session support allows you to register arbitrary numbers of variables to be preserved across requests. When a visitor accesses your site, PHP will check automatically (if session.auto_start is set to 1) or on your request (explicitly through session_start() or implicitly through session_register()) whether a specific session id has been sent with the request. If this is the case, the prior saved environment is recreated. " FOR COOKIE == " Cookies are a mechanism for storing data in the remote browser and thus tracking or identifying return users.
