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

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
// 創建通道
$channel = $connection->channel();

// 創建隊列
$channel->queue_declare('hello', false, false, false, false);

$msg = new AMQPMessage('Hello World!');
// 通過預設的交換機發送消息到隊列 (消息內容, 預設交換機, 路由鍵);
$channel->basic_publish($msg, '', 'hello');

echo " [x] Sent 'Hello World!'\n";

$channel->close();
$connection->close();

# receive.php
<?php
require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;

$connection = new AMQPStreamConnection('localhost', 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";
};

$channel->basic_consume('hello', '', false, true, false, false, $callback);

while ($channel->is_consuming()) {
    $channel->wait();
}

$channel->close();
$connection->close();

運行
