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

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

}
flock($fp, LOCK_EX);
fwrite($fp,date("Y-m-d H:i:s",time()).": ".$msg."\n");

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：
