$_request ["request"] in a restful api <p>I am learning to program a restful api and I am confused about some code in this tutorial.</p> <p><a href="http://coreymaynard.com/blog/creating-a-restful-api-with-php/" rel="nofollow">http://coreymaynard.com/blog/creating-a-restful-api-with-php/</a></p> <p>They used </p> <p><code>$_REQUEST["request"]</code> </p> <p>for the request uri. I am trying to understand the reason why I'd do this instead of </p> <p><code>$_SERVER["request_uri"]</code></p>
