Cron PID and php?

Question

PHP

Good evening, tell me how to transfer the pid of the cron process to the php file?
More detailed: there is a certain function that the user can run, after a minute cron pulls it up and executes it, the problem is that the user could interrupt the process. Other than stopping cron, there are no other ideas.

Answer 1

php.net/manual/ru/function.getmypid.php
php.net/manual/ru/function.posix-kill.php

Answer 2
