Multible stopwatches for php webpage

for an appointment system, the presence time of customers must be counted and stored.

For a php website, on which I have to stop the time of different users (simultaneously), I need a button for each user that I can click to start and then stop the time. The time that was counted must then be entered into the database (per user).

The button must generally be green, but once 15 minutes of time has been counted the button must turn orange, after another 5 minutes the button must turn red.

As soon as you click the button to stop the time, the button must disappear and the minutes that were counted are entered into the database.

the time may only stop when you click on the button. When the page is reloaded, the time must not stop, but must continue to be counted

I hope you understand what I mean :-)
