1. 启动个RabbitMQ用于测试

docker run -d --name some-rabbit-mgr -p 8080:15672 -p 5672:5672 rabbitmq:3-management

2. 创建生产者 send.php

<?php

use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;

require_once __DIR__ . '/vendor/autoload.php';

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

$channel->queue_declare('hello', false, false, false, false);

$msg = new AMQPMessage('Hello World!');
$channel->basic_publish($msg, '', 'hello');

echo " [x] Sent 'Hello World!'\n";

$channel->close();
$connection->close();

3. 创建消费者 receive.php

<?php

use PhpAmqpLib\Connection\AMQPStreamConnection;

require_once __DIR__ . '/vendor/autoload.php';

$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\n";

$callback = function (PhpAmqpLib\Message\AMQPMessage $msg) {
    echo ' [x] Received ', $msg->body, "\n";
    $msg->ack(); // 手动确认消息
};

// 第四个参数改成false不自动确认消息
$channel->basic_consume('hello', '', false, false, false, false, $callback);

while ($channel->is_open()) {
    $channel->wait();
}

$channel->close();
$connection->close();
