Try setting a cookie this way :

setcookie("LoginCookie", $value, time()+$seconds);

where $seconds is a big number eg 3 years (3*365*24*60*60).

and on your pages check if the cookie still exists :

   if(isset($_COOKIE["TestCookie"])) ...

I think what you're looking for is storing a cookie on the user's machine.

http://en.wikipedia.org/wiki/HTTP_cookie

a quick google search for "PHP Cookie tutorial" turned up a couple results.

edit: I should add that you should look up things specific to authentication cookies if using this to bypass user login. You don't want someone editing the cookie for your site and just changing the username to allow them to login as someone else.

Write a cookie on the client's machine and set its expiration date to 'never'. One thing you should know that if the user delete's his/her cookies/temp files then they'll be required to log in again.
