注意：默认根目录已经安装composer下载安装rabbitmq（php-amqplib/php-amqplib）扩展

fanout模式消息队列生产者


publish.php

<?php
    require_once __DIR__ . '/vendor/autoload.php';
    use PhpAmqpLibConnectionAMQPStreamConnection;
    use PhpAmqpLibMessageAMQPMessage;
    
    $dbName = 'sanqing';
    $dbPwd = '111111';
    $tableName = 'order';
    
    $connection = new AMQPStreamConnection('localhost', 5672, $dbName, $dbPwd, $tableName);
    $channel = $connection->channel();
    $exc_name = 'exch';
    $channel->exchange_declare($exc_name,'fanout',false,false,false);
    $data = 'this is fanout message';
    $msg = new AMQPMessage($data,['delivery_mode'=>AMQPMessage::DELIVERY_MODE_PERSISTENT]);
    $channel->basic_publish($msg,$exc_name);
    $channel->close();
    $connection->close();

fanout模式消息队列消费者


sub.php

<?php
    require_once __DIR__ . '/vendor/autoload.php';
    use PhpAmqpLibConnectionAMQPStreamConnection;
    
    $dbName = 'sanqing';
    $dbPwd = '111111';
    $tableName = 'order';
    
    $connection = new AMQPStreamConnection('localhost', 5672, $dbName, $dbPwd, $tableName);
    $channel = $connection->channel();
    $exc_name = 'exch';
    $channel->exchange_declare($exc_name,'fanout',false,false,false);
    list($queue_name,,) = $channel->queue_declare('',false,false,true,false);    
    $channel->queue_bind($quene_name,$exc_name);
    $callback = function($msg){
        echo 'received '.$msg->body."n";
        $msg->ack();
    };
    $channel->basic_qos(null,1,null);
    $channel->basic_consume($queue_name,'',false,false,false,false,$callback);
    while($channel->is_open()){
    	$channel->wait();
    }
    
    $channel->close();
    $connection->close();

可以在复试一份sub.php改名sub2.php

运行sub.php和sub2.php

php sub.php

php sub.php

运行publish.php

php publish.php

sub.php和sub2.php都能收到信息，这就是fanout模式
