Need to run php script on server 1 time per second?

Question

Task Schedulers

I'm not strong in working with cron, I think that I can somehow do it so that it can be used to run script.php once a second. Who knows tell me

Answer 1

Cron does not know how to run tasks per second.
You either need to run an infinite wrapper loop and run tasks every second in this loop. And put a watchdog in the crowns, which will pick up your wrapper if it falls.
The second option is to use something more advanced like snaked:

Answer 2

* * * * * user-name command to be executed
