title: How to communicate from php to Android
body: <p>I am making a location application, where user can parameter some function from the server, so I want the server to begin a communication with the phone of the user.
  But firstly, I want to open a communication with an android, from the php.</p>
  
  <p>Is there a way to communicate with an android phone from a php server?</p>
  
  <p>I already use the communication from android with HTTP to server with return of <code>JSONObject</code>, but I cant find anything for a php call to android.</p>
  
  <p>I think its exactly like the application which can make your phone ring.</p>
