It looks like you are not sending any OAuth Authorization header which is required. This is a little bit of a tricky task since it requires that you also create a signature from the parameters and oauth tokens so as a starter you might want to read this documentation: http://oauth.net/core/1.0a/

Alternatively there are some OAuth PHP libraries out there which will do that part for you: http://oauth.net/code/
