Answer 1

You could add a PHP script to your crontab to automatically run the script at defined intervals. From the command line, enter crontab -e to add the entry to your crontab.

When you don't have access to cron jobs or scheduled tasks on your server, you can use online services such as http://pingability.com/ to hit your script at specified intervals. It is not perfect, but you can build in some kind of secret key and code that makes sure that the script doesn't get run multiple times within a certain time period. Might seem a little hacky, but I've used it on live systems to send out daily emails and it's been working fine for over a year now.
