online list

[Demonicman]

how could i make an online list with what i have?
i could make a file with the online people, but if they dont click logout, they wont be taken off the list...
anyone got any example? ill give my layout to check if they are logged in


<?php

//checks cookies to make sure they are logged in
if(isset($_COOKIE['ID_my_site']))
{
$username = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
$check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error());
while($info = mysql_fetch_array( $check ))
{

//if the cookie has the wrong password, they are taken to the login page
if ($pass != $info['password'])
{ header("Location: login.php");
}

//otherwise they are shown the member area
else
{
}
}
}
else

//if no cookie then show this
{
}
?>

Just saying since you seem to be very good at PHP but why not simply use something like time to your side eg if the user has no activity then he counts as logged out. Or to use the time to log out the user automatically ?
