Using OAuth authorisation with YQL

I want to sign my YQL requests with OAuth to take advantage of the higher bandwidth allowed, but I'm h开发者_Python百科aving problems finding any upto date example of how to do it. ( I am using it in a PHP / JQuery system).

http://paul.donnelly.org/2008/10/31/2-legged-oauth-javascript-function-for-yql/ doesnt work any more and the Yahoo OAuth dont mention using it in YQL examples

Also can I just use 2 legged authorisation instead of 3?
