    }
}

> composer.phar install

生产者

# send.php
<?php
require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLibConnectionAMQPStreamConnection;
use PhpAmqpLibMessageAMQPMessage;
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
// 创建通道
$channel = $connection->channel();
// 创建队列
$channel->queue_declare('hello', false, false, false, false);
$msg = new AMQPMessage('Hello World!');
// 通过默认的交换机发送消息到队列 (消息内容, 默认交换机, 路由键);
$channel->basic_publish($msg, '', 'hello');
echo " [x] Sent 'Hello World!'
";
$channel->close();
$connection->close();

消费者

# receive.php
<?php
require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLibConnectionAMQPStreamConnection;
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();
$channel->queue_declare('hello', false, false, false, false);
echo " [*] Waiting for messages. To exit press CTRL+C
";
$callback = function ($msg) {
    echo ' [x] Received ', $msg->body, "
";
};
$channel->basic_consume('hello', '', false, true, false, false, $callback);
while ($channel->is_consuming()) {
    $channel->wait();
}
$channel->close();
$connection->close();

运行

# shell 1
php receive.php
# shell 2
php send.php
