Check the user input password against your db (hashed/encrypted) credential entries. If match is found define a valid_session, a timeout_interval, and a session_start with php Session variables. Upon loading any page, check the value of the valid_session,
if the timeout interval is expired, change the value of the valid_session variable (to redirect the user to the login page),
else reset your timeout interval by assigning the current timestamp to the session_start variable.
Upon exiting the browsers, session variables won't be kept, thus redirecting the user to the login page on next attempt to open the webpage.
