for the googlers. json_encode() adds double \

$message = "\ue04a";
$body['aps'] = array(
                   'alert' => $message,
                   'sound' => 'default',
                   'type'  => $type,
                   'param' => $param
               );

$payload = json_encode($body);
$payload = str_replace("\", "\\", $payload);
