    logoff user with php *urgent*

    Hello,

    If somebody could help me with this one it would be very nice,

    the story:
    I need to check if a user is online or not at the moment i am doing a user
    logoff with javascript but this is not browser proof so it doesn't work all
    the time. or doing it with a for() statement that writes every 20 sec the
    last unix time to a database, this doesn't work because the for() statements
    stops executing the rest of the page so that doesn't work either

    the problem:
    i can only have one user online for a group, so i have to check if the first
    that logges in for a group is online or not, i have a check time of 1 minut
    so if a user logges off, a new user can login after a minut.

    the reason:
    so you think what is the problem put a logoff button on the screen and your
    finished, well that would be the answer if i wasn't developing a page for
    idiots that destroy the browser window by alt-f4 or the cross instead of the
    logoff button.

    so hope somebody hacked this problem before.

    Thanks in advance

    (sorry for the multi post)

      You can have function check_timeouts( ) and store_time() that are called
      everytime a page is requested.

      The store_time function only has to store the current_time.
      The check_timeouts function has to compare current_time with stored_time.
      If the difference for a user > 60, log the user out.

          You can't. All you can do is to figure out who accessed your
          site within the last X minutes, hours, or days.

          Of course. You must assume that the user is offline, unless you
          have reasons to believe otherwise (e.g., a recent access to a page
          on your site with that user's credentials).

          Cheers,
