How to run cron job every 20 seconds

If you are using the Cron Jobs feature from your hosting or your server crontab, you can run cronjob every 20 seconds by setting up 3 cronjobs running every minute, the second one with a 20-second delay:

* * * * * curl https://example.com/cron.php
* * * * * sleep 20 && curl https://example.com/cron.php
* * * * * sleep 40 && curl https://example.com/cron.php

Now your cron.php will run every 20 seconds.
