OAuthSimple - a very simple OAuth 1.0 signed request generator
See source comments for usage examples
OAuthSimple aids in building valid OAuth 1.0 requests. It does not perform token requests by itself, however you can use it to build the request calls.
Guido Schlabitz has provided a useful example for how to use OAuthSimple to connect to Google http://github.com/jrconlin/oauthsimple/blob/master/php/example.php
OAuthSimple accepts arguments in a variety of formats and returns a structure containing valid elements, including a fully structured URL, an Authorization header and the signature value. You should only use either the Authorization Header (as per the spec), or the fully structured URL. (Again, see source comments for appropriate usage.)
