PHP实现RabbitMQ

本文主要是介绍PHP实现RabbitMQ，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

类封装

定义一个名为 rabbitmq.php的类文件

<?php
class RabbitMQ {
        private $connect;//连接对象
        private $channel;//
        private $exchange;//交换机对象
        private $exchange_name;//交换机名称
        private $exchange_type;//交换机类型
        private $queue;//对列对象
        private $queue_name;//队列名称
        private $queue_type;//对列类型
        private $call_back_fnc;//回调函数
        private $is_ack;//是否确认收到消息

        public function __construct($params=[], $persistent_flag=false) {

    flock($fp, LOCK_UN);

} 

生产消息

定义一个名称为sender.php的文件

<?php
require_once './rabbitmq.php';
$config = [
    'host' => '127.0.0.1',      //IP地址
    'vhost' => '/',             //主机
    'port' => 5672,             //端口号
    'login' => 'guest',         //用户名
    'password' => 'guest',       //密码
];
$mq = new RabbitMQ($config);   // 初始化（rmq连接操作）;
if ($mq) {
    $mq_route = 'push_data_to_routing';  // 路由
    $mq_exchange = 'push_data_to_exchange';  // 交换机
    $mq_queue = 'push_data_to_queue';  // 队列
    // 建立连接，设置交换机，设置队列
    $exchange_params = [
        'exchange_name' => $mq_exchange,
        'exchange_type' => AMQP_EX_TYPE_DIRECT,
        'flag' => AMQP_DURABLE,
    ];
    $queue_params = [
        'queue_name' => $mq_queue,
        'exchange_name' => $mq_exchange,
        'routing_key' => $mq_route,
        'flag' => AMQP_DURABLE,
    ];
    $publish_params = [
        'routing_key' => $mq_route,
    ];
    $data_list = ['iphone','honor','vivo','xiaomi','oppo'];
    $mq->setExchange($exchange_params)->setQueue($queue_params);
    foreach ($data_list as $item){
        $publish_params['message'] = $item;
        $mq->publishMessage($publish_params); //推送
    }
}

接收消息

定义一个名称为receiver.php的文件

<?php
require_once './rabbitmq.php';
$config = [
    'host' => '127.0.0.1',      //IP地址
    'vhost' => '/',             //主机
    'port' => 5672,             //端口号
    'login' => 'guest',         //用户名
    'password' => 'guest',       //密码
];
$mq = new RabbitMQ($config);
$mq_route = 'push_data_to_routing';
$mq_exchange = 'push_data_to_exchange';
$mq_queue = 'push_data_to_queue';
$exchange_params = [
    'exchange_name' => $mq_exchange,
    'exchange_type' => '',
    'flag' => AMQP_PASSIVE,
];
$queue_params = [
    'queue_name' => $mq_queue,
    'flag' => AMQP_PASSIVE,
];
$mq->setExchange($exchange_params)->setQueue($queue_params);
$mq->consumeMessage([
    'callback'=>function($msg){
        sleep(2);
        var_dump($msg);
        return true;
    }
]);

执行

win+R 调出cmd，切换至代码所在目录，一个窗口执行sender.php 一个窗口执行receiver.php

结果如下：
