Having Trouble Using A URL As A Parameter

I suppose that depends on how much you trust SimplePie. It's just that you are effectively allowing anyone to have your PHP code load any document of their choosing. I have no idea how SimplePie loads/parses a remote document. If it's an option, they may just have it locked down tight. However, unless you need to let you users pop in any feed of their choosing, you could always just provide a list of urls (or websites) that you trust. IF the URL is not part of that domain, reject it. On the other hand, I think I remember seeing SimplePie demo with a write in text field to do exactly what you are doing.
