Please Help With Old Rss Php Parser

system · November 30, 2012, 6:08pm

This code scrambles the Title, Description and Link results so that the Description regularly comes up one item earlier than the Title and Link. I suspect that it’s in the function createHtmlFromRSSUrl. It’s old code, but really useful from 2008 and ScarySoftware who apparently met their demise. Can anyone help straighten out the loops in this conversion?
