I am VERY new to PHP (hence I am asking the experts out there) and I have been using PHP code in a webpage to download certain RSS feeds within a table, but it sometimes pulls up more informations than others, and I cant understand why. I was told that I could need a cache file...but I have no idea how to set one up...or if I even need one.
I included the full code (below) and if you refresh the page several times, you should notice that you will randomly pull more/less information. Why?
thanks in advance for all your help!
