RSS Tools in PHP

What i need is a set of RSS management and filtering tools in PHP. I need a couple of functions to include in my own software. I need the following features to be developed: - Multiple RSS combiner. I can input as many RSS feeds i want and they are combined in one output. Just like RSS Magician ([login to view URL]) but i don't need a new RSS to be generated and i want this function very fast. - RSS sorting. All the entries from the RSS feeds combined must be randomly or alphabetically sorted. This must be an option to choose. - Word replacement. All the text from the entries from the RSS feeds combined should be replaced with words from an .txt dictionary. Just like RSS Magician ([login to view URL]) - Custom page for every entry. When the user clicks in the entry title, instead of opening the feed URL, a page must be opened with the entry title and description and a "Read more" link. This link is the link to the link in the rss feed entry. If you're a good coder, you can do it. Or can't you? :D Please, give me a sample of your work. As i said before, this will be integrated with my own software, so nothing must be beautiful. Just like an API. I don't need an interface at all. Just tell me how it works and how i can integrate it with my own script.
