You've said what should happen, but you don't say what is happening. Or if the book you're copying this from is any help at all in explaining anything.

As @NogDog wrote in your previous question

NogDog * Are you, in fact, testing this with a web server (as opposed to just calling the script directly on your computer via PHP)?

And you replied

bertrc I just calling the script directly on my computer via PHP

Has this changed? Because you need a server to serve http.
