Is there any way to create a 60-second countdown in PHP that is accurate to microseconds?
It would be nice to write it with ajax accurate to seconds, but I don’t know how to solve it in microseconds. Please solve it! ! !

Do you want to use php or js to implement the countdown?
What is the purpose of the countdown?
Should this countdown be displayed to users?
