There are different ways to do this  but the server can t detect when de browser gets closed so destroying it then is hard    timeout session    Either create a new session with the current time or add a time variable to the current session  and then check it when you start up or perform an action to see if the session has to be removed   session start      SESSION  timeout     time      if 100 seconds have passed since creating session delete it  if time   -   SESSION  timeout    gt  100        unset   SESSION  timeout         ajax   Make javascript perform an ajax call that will delete the session  with onbeforeunload   a javascript function that calls a final action when the user leaves the page  For some reason this doesnt always work though    delete it on startup    If you always want the user to see the login page on startup after the page has been closed you can just delete the session on startup    lt   php session start    unset   SESSION  session       and there probably are some more
