PHP: running scheduled jobs (cron jobs)

Question

I have a site on my webhotel I would like to run some scheduled tasks on. What methods of achieving this would you recommend?

What I’ve thought out so far is having

Answer 1

I would outsource the cronjobs with www.guardiano.pm and call a url every X minute. When your url (i.e www.yoursite.com/dothis.php) is called than you execute some code. If you don't want to let the web request the page when you want you can allow only request in POST and send some parameter that only you know with guardiano.pm

Thats what I would do because I do that on my pet projects. Have fun!
