how to call a link/href evey x hours?

Question

Is there a way to make a function "PHP/JS" or a cron job to call a link/href every 12 hours for example?

Thanks in advance!

Answer 1

To run a PHP script via cron job every 12 hours, you can do the following:

0 */12 * * * curl -s -o /dev/null http://example.com/your-php-script.php

Answer 2

There are attempts at this, e.g.

• https://github.com/StefanLiebenberg/cron.js
• http://elijahr.blogspot.de/2009/03/javascript-cron.html (https://gist.github.com/4403566)

Otherwise it might be simpler to just write a traditional cron script, if possible.

Answer 3

Of course you could do it yourself with a cron job, but there are monitoring services that will check that a page is accessible and returns the expected data, and email or text you if it fails.
