Set up a PHP OAuth Provider

Alright I am trying to set up an OAuth Provider in PHP, but I just cannot get the hang of it. I've been referenced to this page a number开发者_运维知识库 of times, but I cannot wrap my head around it. Could someone help me out, step by step, or reference me to a more direct guide? Thank you very much.

Pate's is good and here is another one by Rasmus:

I usually use the Zend_OAuth component (the whole 2 times ive implemented it, haha). The manual has some pretty clear instructions. This tutorial for it might also be helpful.
