//连接mq
$connect = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest', '/', false, 'AMQPLAIN', null, 'en_US', 5.0, 5.0);
//建立通道
$channel = $connect->channel();
$queueName = 'hello';
//确认投放队列,并将队列持久化
$channel->queue_declare($queueName, false, true, false, false);
//异步回调消息确认
$channel->set_ack_handler(
    function (AMQPMessage $message) {
        echo '消息确认内容' . $message->body . PHP_EOL;
    }
);
//异步回调,消息丢失处理
$channel->set_nack_handler(
    function (AMQPMessage $message) {
        echo '消息丢失' . $message->body . PHP_EOL;
    }
);
//开启消息确认
$channel->confirm_select();
for ($i = 0; $i < 100; $i  ) {
    $pushData = "hello world---------$i";
    $msg = new AMQPMessage($pushData);
    $channel->basic_publish($msg, '', $queueName);
    echo $pushData . PHP_EOL;
}
//阻塞等待消息确认 监听成功或失败返回结束
$channel->wait_for_pending_acks();

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

消费者

$channel = $connect->channel();
$queueName = 'hello';
$channel->queue_declare($queueName);
echo '创建队列成功' . PHP_EOL;
$callback = function ($msg) {
    echo '接收到消息' . $msg->body . PHP_EOL;
};
$channel->basic_consume($queueName, '', false, false, false, false, $callback);
while ($channel->is_consuming()) {
    $channel->wait();
}
