I need a PHP script that I can upload to my linux-based website that monitors another webpage for 1 or 2 keywords every minute. This webpage I'm monitoring is inside a VBulletin forum and I must be 'logged in' to see it. **That's the hardest (and most important part) part of this project!**
Every time a keyword appears, a simple notification email is sent to a list of email addresses. These emails must be sent separately. In other words, if I list 6 emails, all 6 CANNOT appear in the "To", "CC" or "BCC" field. Each email must be sent separately in a loop or batch.
I do not need a GUI or User Interface. I am perfectly happy editing variables in a PHP file. All I ask is that you **please** comment everything well.
Finally, I'm very confident creating cron jobs on my Hostgator Linux server. Please supply the URL to run the CRON job upon completion.
I only want the script to send an email **once every 5 minutes**. I'm not sure if a MySQL database will be required to store timestamps and track sent emails. Please advise.
