title: Google OAuth 2 PHP call to userinfo
body: <p>I am trying to use Google's OAuth2 API. In their generic documentation, they mention a call called UserInfo: <a href="http://code.google.com/apis/accounts/docs/OAuth2Login.html#userinfocall" rel="nofollow">http://code.google.com/apis/accounts/docs/OAuth2Login.html#userinfocall</a> , which would allow me to retrieve user ids, email, name and other basic stuff.</p>
  
  <p>However I cannot find it in their PHP client library: <a href="https://code.google.com/p/google-api-php-client/" rel="nofollow">https://code.google.com/p/google-api-php-client/</a></p>
  
  <p>Where is it?</p>
