websocket.org echo example does nothing for me. Says my browser supports it (chrome10 Win), but nothing happens on connect.


maybe you could try...

when the user logs in:

$user = "logged-in/$username";
$user = fopen($user, 'w') or die('ERROR');

on logout:


to list users:

$users = sort(glob('logged-in/*'));
foreach ($users as $user) {
  print $user; 
  print '<br />';

good luck :)


In order to track users, you'll need some sort of logon process. The previous post provides a low-end approach to doing this. This may satisfy your needs, otherwise you'll want to look at using a database to keep the user information, including their login status. You need a process to force a logoff for anyone who is inactive for a set period of time. Otherwise, everyone will eventually show as logged on / active.

good point chrishea; i'm not very familiar with mysql... lol, thats why my cms is flat file!
