PHP使用enqueue/amqp-lib实现rabbitmq任务处理

$factory = new AmqpConnectionFactory([

    'port' => '5672',//端口
    'vhost' => '/',//虚拟主机
    'user' => 'admin',//账号
    'pass' => 'admin',//密码

//声明并创建主题

$fooTopic->setType(AmqpTopic::TYPE_FANOUT);

//删除主题
$context->deleteTopic($fooTopic);

//声明并创建队列
$queueName = 'rabbitmq';
$fooQueue = $context->createQueue($queueName);
$fooQueue->addFlag(AmqpQueue::FLAG_DURABLE);
