On the upstairs, you change the cookie to session,cookie the session time can be set, when the set time is not expired, even if the browser is closed, the next time the visit, or do not need to enter the account password, with the session, close the browser, the session will be destroyed.

The login information is saved in the cookie, the browser closes, and the cookie disappears.

How to write to see your original code, it is relatively simple to read into the account password cookies two sentences to comment off the line

It would be nice to hide the Setcookie and cookie statements.

1. As LS says, use the session
2. If you do not want to consume server resources, use JavaScript to determine if the browser shuts down and then destroys the cookie.
