用PHP尝试RabbitMQ（amqp扩展）实现消息的发送和接收

消费者：接收消息

逻辑：
创建连接-->创建channel-->创建交换机-->创建队列-->绑定交换机/队列/路由键-->接收消息

$e_name = 'e_linvo'; //交换机名

}
$channel = new AMQPChannel($conn);

//创建交换机

$ex->setName($e_name);
$ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型

//创建队列
$q = new AMQPQueue($channel);
$q->setName($q_name);
$q->setFlags(AMQP_DURABLE); //持久化
echo "Message Total:".$q->declare()."\n";

//绑定交换机与队列，并指定路由键
echo 'Queue Bind: '.$q->bind($e_name, $k_route)."\n";

//阻塞模式接收消息
echo "Message:\n";
while(True){
    $q->consume('processMessage');
    //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答

生产者：发送消息
