It's my first post in here. Sorry if it's in the wrong section, but as I don't know how to do what I'm planning (if it's possible with PHP), I also don't know where to post it.
I'm involved in a project where I need to check the contents of a website every 10 minutes and, based on the results, update some entries on my database. By default, I would use the sleep function of PHP, but this process should happen constantly, not only when the page is accessed (it's kind of like a "background" program that would be always running in the server, checking data every 10min).
There is a website called http://www.changedetection.com that does that. It checks when a webpage has changed and notify you by e-mail.
Does anyone knows how to do that? Is it possible to do with PHP? Any documentation or article would help.
Thanks in advance,
Fergo
