ok i am still new to PHP
and i am sure this is not the correct way to get this done, but heck it worked
bried descript of what it does:
visits http://board.bitefight.org/search.php?action=24h and grabs the last 20 posts
and extracts data such as, date and time, user who posted, subject, link, and what forum posted under
it then puts it into and RSS feed for others to use.
the script seems to run fast and not have any errors loading. but as stated above im new and im sure this isnt the correct way to pull it off. but when your knew you have to K.I.S.S.
let me know what you guys think

what i did was find the values of the first line, extracted it and then replaced them with ~'s. then looped so next time it searched it would come down to the next line of data to extract from
ran into a lot of problems but worked them out
thanks in advance for any criticism or suggestions
