and i am asking how to know who is online like facebook.
you can see a list of the people who are online and chat with them. so this is what i am asking about
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.
