title: Use Google Drive API "without" authentication screen from php
body: <p>This is the scenario I'm facing.
  I have a php powered web application from which I need to access some links of files that I have on my Google Drive account. I ONLY need to access to my files in MY account, because I store same images that I have to serve to different clients.
  I tried to look into the Google Drive API documentation, but I don't need OAuth and the consent screen. The app should access MY Google Drive account in "background", just to retrieve some informations that it has to present to the clients, without them having to do anything.</p>
  
  <p>I read very similar questions here on StackOverflow, but none of those really helped me... some mention the use of Service Accounts, other say that they are not useful for this purpose. </p>
  
  <p>Could you help me to understand which is the best approach in this scenario? Thanks a lot in advance!</p>
