$channel = $connection->channel();

$channel->queue_declare('task_queue', false, true, false, false);

$data = implode(' ', array_slice($argv, 1));
if(empty($data)) $data = "Hello World!";
$msg = new AMQPMessage($data,
                        array('delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT)
