    Hello friend

    I want to know my user is online or not.

    How can I?

    Can someone give me the PHP code for it?

    If you only want to know how many users are currently online, try

    count(scandir(ini_get("session.save_path")));

    This will give you the number of currently active sessions. However, a session may live longer than the user is actually on site.

    If you want to know if a user is on site, you will need to follow the user from his login and track what he is doing. You will need to count the seconds from each action of the user and set your own timeout where you decide for yourself if the user is still online or not (you'd determine it by guessing that a user who has not been clicking anywhere during the past 60 seconds has probably left the site). You can also monitor login/logout activities (but many users don't logout, so this is not reliable).

    The bottom line: It is not really possible to perfectly track users unless you are monitoring all actions such as mouse movements (through JavaScript and asynchronous messages to your server), clicks, login/logout and more. There is not "PHP code" for doing that. You will have to develope your own.

    Yep. This is going to be more of a front end talking to the back end thing. You'll have to track what the user is doing and periodically feed it to the backend, updating the session along the way.

    Be careful though, this kind of tracking does break some privacy laws in some countries. Some allow you a pass if you notify the user.
