How to make script that runs all the time?

Question

I would like to make a script that would run all the time at server or at least at certain times, because I have some actions I want to do at certain times. For now I have a script that refreshes every 1 second and that is good, but only in case when user is on the site. When site is not opened, it doesn't work. Any solutions?

EDIT: What would be better choice of suggested solutions, cron job or PHP daemon?

Within a while loop, at the bottom of the script, you could add sleep(1); which would stop the script for 1 second. — Paul McLoughlin, Feb 27 '14 at 22:09

If you're on a Linux system, then you could use the CRON Daemon which allows users to execute scripts or commands (or groups of commands) at a specified time.

You would schedule a CRON event using Crontab (CRON Table). Crontab is a file which contains the list of all cron jobs and at what time they're due to run (think of it as a schedule)

Creating an entry into Crontab has it's own peculiar syntax beyond the scope of this post, but for more information.

You can set up your PHP to run as a daemon. I've implemented this for some of my scripts that need to check for data constantly.

I used Upstart for this job and pretty much followed the path from this post on Stack Overflow:

He also has links to the source where he learned it from.
