I used js to write a 20-second countdown, and then I wanted to ask if there is a way to get the number of seconds at a certain moment in php, and then save it in the database!

If you want to get the number of seconds at a certain moment, you can add a trigger function to this time, clear the timer, get the value and store it in the database through ajax
