loops - How do i run a php script every second?

Question

I am currently writing a online game. Now I have to check if an event happen (checking timestamp in database) and depending on that execute some actions. I have to check for an event every second.

I wanted to use a cronjob but with cron you can run a script only every minute.

My idea was to use cron and loop 60 times in my php script. But I think this isn't the best solution.

So whats the best way to run a script every second?

Answer 1

Why not modify the script so that it just repeats the code every second? This will reduce the parsing overhead and be less complicated.
