RabbitMQ-php最简单的模式（hello word）

{
    "require": {
        "php-amqplib/php-amqplib": ">=2.6.1"
    }
}

消费者：receive.php

<?php
require_once '../vendor/autoload.php';
//创建一个 RabbitMQ 的连接：
$connection = new \PhpAmqpLib\Connection\AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();
//声明队列
$channel->queue_declare($queue = 'queue_for', $passive = false, $durable = true, $exclusive = false, $auto_delete = false);

echo " [*] Waiting for messages. To exit press CTRL+C\n";
$callback = function ($msg) {
//    print_r($msg);die;
    $msgArr = json_decode($msg->body, true);
    echo "正在处理count为" . $msgArr['count'] . "的队列....\n";
    for ($i = 0; $i < $msgArr['count']; $i++) {
        $myfile = fopen("testfile.txt", "a");
        $txt = $i . ' 读取到的时间：' . $msgArr['time'] . "写入文件的时间" . date('Y-m-d H:i:s');
        fwrite($myfile, $txt . " \n");
        fclose($myfile);
    }

    echo "count为" . $msgArr['count'] . "的队列处理完成！\n";
    //告诉rabbit 已经处理完消息，是通过delivery_tag判断  是自增的
    //RabbitMQ只有在收到消费者确认后，才会从内存中删除消息，如果消费者忘了确认（更多情况是因为代码问题没有执行到确认的代码），将会导致内存泄漏
    //一定要保证消息确认在任何情况下都可以发出，否则即使消费者处理完成，RabbitMQ也不会把消息在内存中清除，
    //在该消费者断开连接之后，还会把消息转发给其他消费者重新处理，将引发难以预计的问题
    $msg->delivery_info['channel']->basic_ack($msg->delivery_info['delivery_tag']);
};
//消息确认之前  不接受其他消息
//$channel->basic_qos(null, 1, null);
//从队列中异步获取数据 //$no_ack 是否关闭确认消息收到
$channel->basic_consume('queue_for', '', false, $no_ack = false, false, false, $callback);
while (count($channel->callbacks)) {
    $channel->wait();
}
$channel->close();
$connection->close();
