I've noticed a new trend in fan sites these days; dev trackers. They scan the official forums of a fan site, and save posts from developers in a database. Some sites even provide RSS feeds for other fan sites to leech off of. Here's an example; http://www.silkyvenom.com/?page=devtracker
Recently I've come across an RSS "bootleg" which is also providing RSS feeds for certain sites that don't provide RSS feeds. These feeds display the latest news for that site. Here's an example of someone doing that; http://bootleg-rss.g-blog.net/
Now to my questions;
- What would be the best way to do this using PHP and MySQL?
- How can I update these feeds every, say, 1 hour? The "duh" answer would be to just have the script check the last update time when someone hits your web site. However, say I make 100 feeds. I can't be checking all of those feeds when that one user refreshes the web browser on my site. I need a silent way to do this. Is there a way to run a PHP script in the "background" on my web server? That runs on it's own? Or is there another way to go about doing this?
Thanks for your time.
