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:
pecl install amqp
安装PHP的AMQP扩展。php-amqplib/php-amqplib
。<?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();
$channel->queue_declare('hello', false, true, false, false);
function sendMessage($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();
}
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
$log = new Logger('AMQP');
$log->pushHandler(new StreamHandler('php://stdout', Logger::INFO));
$log->info('Connected to RabbitMQ');
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。
