$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$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)
                      );

echo " [x] Sent ", $data, "\n";

echo ' [*] Waiting for messages. To exit press CTRL+C', "\n";

$callback = function($msg){
  echo " [x] Received ", $msg->body, "\n";
  sleep(substr_count($msg->body, '.'));
  echo " [x] Done", "\n";
  $msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};

$channel->basic_qos(null, 1, null);
$channel->basic_consume('task_queue', '', false, false, false, false, $callback);

while(count($channel->callbacks)) {
    $channel->wait();
