In php script you have cookies for only current user so you can't do
it without database (SQL or text - doesn't matter)

1. Use session for logging users
2. Make database-driven session handler
3. Now you can get list of users by regular SQL query.

You can also parse session files in /tmp directory instead of making
database-driven handler but I don't think it's good way.
