<?php 

//---- GENERAL INFORMATION ----//
// What happens is that we $.ajax this php file in our angular project, this file will take the TERM and SITE data
// from that $.ajax request and use the "OAUTHSTORE" php class, to make a two-legged OAUTH request to the nounproject
// server. When we get our response we will echo that response, so that our $.ajax callback in our angular project will
// get the json we just recieved from our two-legged OAUTH request.

// Two-legged authentication : authentication without the need of user login ( only need key and secret )
// Three-legged authentication : authentication with the need of user login ( need key and secret, and consumer token)
// GET the term we past in our $.ajax in the URI by $_GET[""] requesting it
// Using variales in a string in php : "{$var} much string"
