title: push notification vibrate option
body: <p>I am trying to implement push notification for iPhone in php. I have done by the following code:</p>
  
  <pre><code> $body['aps'] = array(
                  'alert' =&gt; $message,
                  'badge' =&gt; 1,
                  'sound' =&gt; 'default'
                  );
  </code></pre>
  
  <p>This is sending alert, badge and sound options. Now, how to send the vibrate option?
  Please help me. </p>
