  <pre><code> &lt;?php
   require "connect.php";
   require "parsePHP/autoload.php";
  
  $app_id = "xxxxxxxxxxxxxxxxxxxxxxxxx";
  $rest_key = "xxxxxxxxxxxxxxxxxxxxxxxxxx";
  $master_key="xxxxxxxxxxxxxxxxxxxxxxxxxxxx";
  $MESSAGE = "HI.. Testing";
  
  use Parse\ParseClient;
  use Parse\ParsePush;
  ParseClient::initialize( $app_id, $rest_key, $master_key );
  
  $url = 'https://api.parse.com/1/push';
  $data = array(
      'channel' =&gt; 'Android',
      'type' =&gt; 'android',
      'data' =&gt; array(
          'alert' =&gt; $MESSAGE,
      ),

  $_data = json_encode($data);
  $headers = array(
      'X-Parse-Application-Id: ' . $app_id,
      'X-Parse-REST-API-Key: ' . $rest_key,
      'Content-Type: application/json',
      'Content-Length: ' . strlen($_data),
  );
  
  $curl = curl_init($url);
