前言

---

 

这里我们弱化broker内部构造。将整体分为三部分。

P：producer。生产者。

C：Consumer。消费者。

queue:队列。

后面的代码都依赖于 the php-amqplib API

 

composer安装php-amqplib 

---

 

1. 新建composer.json

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

 2. composer.phar install 

 

Hello World

talk is cheap , show you the code

sender.php

require_once __DIR__ . \'/vendor/autoload.php\';
use PhpAmqpLib\\Connection\\AMQPStreamConnection;
use PhpAmqpLib\\Message\\AMQPMessage;

$connection = new AMQPStreamConnection(\'127.0.0.1\', 5672, \'guest\', \'guest\');
$channel = $connection->channel();


$channel->queue_declare(\'hello\', false, false, false, false);

$data = implode(" ", array_slice($argv, 1));
empty($data) && $data = "Hello World!";

$msg = new AMQPMessage($data);

$channel->basic_publish($msg, \'\', \'hello\');

echo " [x] Sent \'$data\'\\n";

//close the channel and connection;
$channel->close();
$connection->close();

 

receive.php

require_once __DIR__ . \'/vendor/autoload.php\';
use PhpAmqpLib\\Connection\\AMQPStreamConnection;

$connection = new AMQPStreamConnection(\'127.0.0.1\', 5672, \'guest\', \'guest\');
$channel = $connection->channel();

$channel->queue_declare(\'hello\', false, false, false, false);
echo \' [*] Waiting for messages. To exit press CTRL+C\', "\\n";

$callback = function($msg) {
    echo "[x] Received ", $msg->body, "\\n";
    sleep(substr_count($msg->body, \'.\'));
    echo "[x] Done\\n";
};
$channel->basic_consume(\'hello\', \'\', false, true, false, false, $callback);

while(count($channel->callbacks)) {
    $channel->wait();
}

 

执行

打开两个终端,分别执行两个脚本。

终端一：

 

终端二：

 

终端一收到终端二发送的消息。
