cron task or daemon?

Question

linux

Greetings. There is a php script that once a minute (or rather, when the time changes, for example from 12:00 to 12:01) should update certain data. What is better to choose for this, a cron task with minutes * or make the script a daemon process, while(true){ ... sleep(60); } ?

Answer 1

Cron of course. It will be launched for you without you.
The demon will not start without you. Well, or someone can provoke its launch, but there is no guarantee that the time will hit exactly 12:00

Answer 2

of course cron
