How to get/display all logged in users?

The problem I couldn’t wrap my head around was updating the table on logout, as this may never happen if the user doesn’t manually log out.

Solution to that is to simply check which timestamps are older then lets say 30 minutes and delete it from the database. You can check for this everytime someone logs in/out, that way its automated "cron" without any fency crons/scripting.
