Sessions (for authorization) How to detect if the same username/pass is used to login

listenmirndt

Is there a way to display all users "logged in" ? Basically I am trying to detect if multiple logins under the same username are happening.

Thanks

When they log in, store the username in a database/log file, then when they log out have it deleted.

EDIT: just realised this wouldn't work as people could close the browser instead of logging out.

You could possibly use Javascript and the "onExit" body tag.

<script language="Javascript">
    function logOut() {
      document.write("<script language=\"Javascript\" src=\"file/that/logs/people/out.php?username=username\"> </script>");
   }
</script>
<body onExit="logOut();">

file/that/logs/people/out.php?username=username would then contain PHP code that deleted the name from the "logged in" database/log file

My javascript isn't great so it may not be exactly right, but something like that should do the trick.
