This is usually done by updating a datetime or timestamp column in users database table for each user whenever they access a page. Then you pick an arbitrary amount of time, and run a query to see how many rows in that table have a time between that number of minutes in the past and the current time.

Hi....

You can store the session id by using session_id() function and store it in database table.

You also need to add data and time value as well as need to update every time when user will be refresh the page. on base of session_id().

session id must be unique when you will start the surf the site.

Other way is you can calculate the session from session_path by opening the session registration file.
