Hi,

I am trying to build a elgg plugin to push notifications to mobile devices. I have this already configured for GCM push notifications, which works as expected. However, now I am trying to configure it for APNS and it is really difficult to get it working. After a lot of trial and error, I now know for sure that my php functionality is correct and that my certificates work. In order to validate this I tried my implementation of the push notifications in a seperate php script. When I use the exact same code and certificate in the elgg plugin, the script refuses to open the stream_socket_client I use to send the notifications to the APNS server. This is the code I use:

function sendAPNSmessage($devicetokens, $type, $body) {

     $deviceToken = 'XXXXXXXXXXX';
     $passphrase = 'xxxx';
     $message = 'My first push notification!';

     ////////////////////////////////////////////////////////////////////////////////

     $ctx = stream_context_create();
     stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
     stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

     xdebug_break();
     // Open a connection to the APNS server
     $fp = stream_socket_client(
          'ssl://gateway.sandbox.push.apple.com:2195', $err,
          $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

     if (!$fp)
          exit("Failed to connect: $err $errstr" . PHP_EOL);

     echo 'Connected to APNS' . PHP_EOL;

     // Create the payload body
     $body['aps'] = array(
          'alert' => $message,
          'sound' => 'default'
          );

     // Encode the payload as JSON
     $payload = json_encode($body);

     // Build the binary notification
     $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

     // Send it to the server
     $result = fwrite($fp, $msg, strlen($msg));

     if (!$result)
          echo 'Message not delivered' . PHP_EOL;
     else
          echo 'Message successfully delivered' . PHP_EOL;

     // Close the connection to the server
     fclose($fp);
}

When I debug the plugin locally, the $fp stream remains null while the $err is 0 and the $errstr also remains null. Does anybody know why this is the behaviour I see. As this is a copy paste of the functionality that worked outside of the plugin, I think it has something to do with rights/permission/configuration?

Thanks in advance!
