设计一个基于AMQP的PHP应用架构需要考虑多个方面,包括消息队列的配置、生产者和消费者的实现、错误处理、监控和日志记录等。以下是一个基本的架构设计示例:

1. 环境准备

2. 配置RabbitMQ

3. PHP代码架构

3.1. 连接到RabbitMQ

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

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

3.2. 声明队列

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

3.3. 生产者

function sendMessage($channel, $msg) {
    $msg = new AMQPMessage($msg);
    $channel->basic_publish($msg, '', 'hello');
    echo " [x] Sent 'Hello World!'\n";
}

sendMessage($channel, 'Hello World!');

3.4. 消费者

function callback($msg) {
    echo " [x] Received ", $msg->body, "\n";
}

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

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

4. 错误处理和监控

5. 日志记录

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$log = new Logger('AMQP');
$log->pushHandler(new StreamHandler('php://stdout', Logger::INFO));

$log->info('Connected to RabbitMQ');

6. 部署和扩展

示例代码总结

以下是一个完整的示例代码,展示了如何连接到RabbitMQ、声明队列、发送和接收消息:

<?php
require_once __DIR__ . '/vendor/autoload.php';
use PhpAmqpLib\Connection\AMQPStreamConnection;
use PhpAmqpLib\Message\AMQPMessage;
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

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

$log = new Logger('AMQP');
$log->pushHandler(new StreamHandler('php://stdout', Logger::INFO));
$log->info('Connected to RabbitMQ');

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

function sendMessage($channel, $msg) {
    $msg = new AMQPMessage($msg);
    $channel->basic_publish($msg, '', 'hello');
    echo " [x] Sent 'Hello World!'\n";
}

sendMessage($channel, 'Hello World!');

function callback($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();

这个示例展示了如何使用AMQP进行基本的消息队列操作。根据实际需求,你可以进一步扩展和优化这个架构。
