So I have a few websites I need to check very regularly for updated stock.
These websites do not offer an RSS feed of any sort, but I can write a script to scrape their pages and find out if they've updated.
Next step, I want to run this script as a cron job on my shared web server (possible) so that it runs every 10 minutes or so.
But I now want the same cron to push a desktop notification to me if there is an update. Is this possible? I know gmail has desktop notifications which work without having the website open, so I feel as though it's possible.
But am not sure where to start. Is there a library in PHP which allows this?
