Complete code for implementing message queue with PHP and RabbitMQ

This article brings you the complete code for implementing message queues in PHP and RabbitMQ. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

First install the RabbitMQ corresponding to PHP. Here we use php_amqp. Different extension implementations will have subtle differences.
php extension address: http://pecl.php.net/package/amqp
For details, please refer to the official website http://www.rabbitmq.com/getstarted.html

Introduction

config.php configuration information
BaseMQ.php MQ base class
ProductMQ.php Producer class
ConsumerMQ.php Consumer class
Consumer2MQ.php Consumer 2 (can have multiple)

 [ 'host' => '127.0.0.1', 'port' => '5672', 'login' => 'guest', 'password' => 'guest', 'vhost'=>'/', ], //交换机 'exchange'=>'word', //路由 'routes' => [], ];

conf = $conf['host'] ; $this->exchange = $conf['exchange'] ; $this->AMQPConnection = new \AMQPConnection($this->conf); if (!$this->AMQPConnection->connect()) throw new \AMQPConnectionException("Cannot connect to the broker!\n"); } /** * close link */ public function close() { $this->AMQPConnection->disconnect(); } /** Channel * @return \AMQPChannel * @throws \AMQPConnectionException */ public function channel() { if(!$this->AMQPChannel) { $this->AMQPChannel = new \AMQPChannel($this->AMQPConnection); } return $this->AMQPChannel; } /** Exchange * @return \AMQPExchange * @throws \AMQPConnectionException * @throws \AMQPExchangeException */ public function exchange() { if(!$this->AMQPExchange) { $this->AMQPExchange = new \AMQPExchange($this->channel()); $this->AMQPExchange->setName($this->exchange); } return $this->AMQPExchange ; } /** queue * @return \AMQPQueue * @throws \AMQPConnectionException * @throws \AMQPQueueException */ public function queue() { if(!$this->AMQPQueue) { $this->AMQPQueue = new \AMQPQueue($this->channel()); } return $this->AMQPQueue ; } /** Envelope * @return \AMQPEnvelope */ public function envelope() { if(!$this->AMQPEnvelope) { $this->AMQPEnvelope = new \AMQPEnvelope(); } return $this->AMQPEnvelope; } }

ProductMQ.php

channel(); //创建交换机对象 $ex = $this->exchange(); //消息内容 $message = 'product message '.rand(1,99999); //开始事务 $channel->startTransaction(); $sendEd = true ; foreach ($this->routes as $route) { $sendEd = $ex->publish($message, $route) ; echo "Send Message:".$sendEd."\n"; } if(!$sendEd) { $channel->rollbackTransaction(); } $channel->commitTransaction(); //提交事务 $this->close(); die ; } } try{ (new ProductMQ())->run(); }catch (\Exception $exception){ var_dump($exception->getMessage()) ; }

exchange(); $ex->setType(AMQP_EX_TYPE_DIRECT); //direct类型 $ex->setFlags(AMQP_DURABLE); //持久化 //echo "Exchange Status:".$ex->declare()."\n"; //创建队列 $q = $this->queue(); //var_dump($q->declare());exit(); $q->setName($this->q_name); $q->setFlags(AMQP_DURABLE); //持久化 //echo "Message Total:".$q->declareQueue()."\n"; //绑定交换机与队列，并指定路由键 echo 'Queue Bind: '.$q->bind($this->exchange, $this->route)."\n"; //阻塞模式接收消息 echo "Message:\n"; while(True){ $q->consume(function ($envelope,$queue){ $msg = $envelope->getBody(); echo $msg."\n"; //处理消息 $queue->ack($envelope->getDeliveryTag()); //手动发送ACK应答 }); //$q->consume('processMessage', AMQP_AUTOACK); //自动ACK应答 } $this->close(); } } try{ (new ConsumerMQ)->run(); }catch (\Exception $exception){ var_dump($exception->getMessage()) ; }
