~~~ send.php <?php $config = [ 'host' => '127.0.0.1', 'vhost' => '/', 'port' => 5672, 'login' => 'guest', 'password' => 'guest' ]; $conn = new \AMQPConnection($config); $conn->connect(); $channel = new \AMQPChannel($conn); $queue = new \AMQPQueue($channel); $queue->setName('hello'); $exchange = new \AMQPExchange($channel); $result = $exchange->publish('hello world!','hello',AMQP_IMMEDIATE,array()); var_dump($result); receive.php <?php $config = [ 'host' => '127.0.0.1', 'vhost' => '/', 'port' => 5672, 'login' => 'guest', 'password' => 'guest' ]; $conn = new \AMQPConnection($config); $conn->connect(); $channel = new \AMQPChannel($conn); $channel->qos(0,0); $queue = new \AMQPQueue($channel); $queue->setName('hello'); $queue->declareQueue(); $result = $queue->get(); var_dump($result); if (!empty($result)) { echo $result->getBody(); } ~~~ 在send.php中，并未指定exchange的名稱。實際上但未定義exchangeName時，會使用rabbitMQ中系統默認的exchange，默認的exchange是一個name為空的exchange。在使用publish時，會將消息發送到與rote key同名的queue中。 在receive.php中，如果未使用bind exchange，則默認綁定，RabbitMQ中默認的exchange，即為空名的exchange. 這個默認的exchange的Type是direct.
