My question is this: I know very, very little PHP. I know I'm going to have to start from scratch and I know I'm going to have to do lots of work. How difficult is what I want? It seems like it would be on the easy end of the PHP coding meter. I'm sure I'll need one script to pull the information and store it, then a cron job to run it nightly, but I'm kind of unsure where I should start.
I'd very much appreciate any assistance, and I want to thank those that don't just flame me for being a newbie.
