title: Only allow access to PHP file through application
body: <p>I have a PHP file that queries my database and then returns information in XML format back to my application. Right now, if I just go to the URL in the browser and put in the proper parameters in the URL, the information is shown right to me. Is there a way that I can make the PHP page ONLY accessible through the application(iOS and Android)? I have searched, and the only thing that I can find is making the page only accessible through includes, but I don't see how this would restrict the access if the person figured out the php page that included the file. Any suggestions are appreciated!</p>
  
  <p>Thanks</p>
