Archiving a share feed

I have been given the job of incorporating a share feed into our web site and have decided to use PHP and MySQL for the job. I am pretty new to PHP so it is going to be a tough one for me...
I can sort out the basics of just displaying the feed on the page but am having difficulty working out how I am going to archive the material on a daily basis. I need to log the information so that it can be used to generate graphs on the fly of the indices and share prices of the companies involved. What should I be looking at to make this happen?
Any offers gratefully received (and rewarded!)

Well, if you have a MySQL database then you're off to a start.

I'm assuming from your question that you are getting the feed live from a different website at the moment?

So basically you are including the feed via http:// or something and simply displaying it.

What I would do personally, since you'll want to ensure you are grabbing this material at specified times, is use a cron job (every minute or something) to pull down the info and stick it in a mysql table.

You can then use php to report on historical data.

Thanks for this - the points will be yours if you can help me on one more issue.
I am using a MySQL database and the information is coming directly from the stockbrokers so we have to grab the info every few minutes.
The real question comes down to the historical data... how do I make it 'historical' i.e. archive it... should I timestamp it? What's the process?

Yeah, that's exactly it.  Simply timestamp it when you grab it into the database.  That way you can display the last data very simply, then pull historical data out by date/time ranges.
