PHP implements open source RabbitMQ SDK

RabbitMQ is a message queue based on the AMQP (Advanced Message Queuing Protocol) protocol, which is widely used in scenarios such as decoupling and asynchronous processing. As a highly popular dynamic language, PHP also has many open source RabbitMQ SDKs to choose from. This article will introduce how to implement the open source RabbitMQ SDK through PHP to meet everyone's daily development needs.

1. Set up the RabbitMQ environment

Before officially starting the code implementation, you need to set up the RabbitMQ environment first. RabbitMQ supports the installation and use of various systems. For details, please refer to the official documentation: https://www.rabbitmq.com/install.html.

For the sake of convenience, in this article we will use docker to build the RabbitMQ environment. The advantage of using docker is that it can avoid problems caused by different environments. The following is the command to create a RabbitMQ container:

docker run -d --name rabbitmq -p 5672:5672 rabbitmq:3.7.14-management

2. Install the PHP AMQP extension

Before you start using the RabbitMQ SDK, you need to install the PHP AMQP extension. You can install it with the following command:

sudo apt-get install php7.4-dev libpcre3-dev php-dev librabbitmq-dev

git clone https://github.com/alanxz/rabbitmq-c.git

cd rabbitmq-c && mkdir build && cd build

cmake ..

cmake --build .

sudo cmake --build . --target install

sudo pecl install amqp

echo "extension=amqp.so" >> /etc/php/7.4/mods-available/amqp.ini

sudo php -m | grep amqp

After the installation is complete, you can use the AMQP extension in your PHP code.

3. Implement RabbitMQ PHP SDK

Next we start to implement RabbitMQ PHP SDK. This article will introduce two implementation methods: one is implemented by extending amqp through PHP, and the other is implemented by using the officially provided php-amqp library.

1. amqp implementation

amqp is a RabbitMQ client in the PHP extension that supports publishing, consuming and confirming queue services. Its API is relatively friendly, simple and easy to use. Here's a brief introduction to how to use it.

i. Publishing messages

In the amqp extension, use the AMQPExchange class to publish messages. The following is a basic example:

<?php
//连接RabbitMQ服务器
$conn = new AMQPConnection();
$conn->setHost('localhost');
$conn->setPort(5672);
$conn->setLogin('guest');
$conn->setPassword('guest');
$conn->connect();

//创建交换机
$ex = new AMQPExchange($conn);
$ex->setName('exchange-name');
$ex->setType(AMQP_EX_TYPE_DIRECT);
$ex->declare();

//发布消息
$message = 'Hello World!';
$ex->publish($message, 'routing-key');

//关闭连接
$conn->disconnect();
?>

ii. Consuming messages

Use the AMQPQueue class to consume messages. The following is a basic example:

<?php
//连接RabbitMQ服务器
$conn = new AMQPConnection();
$conn->setHost('localhost');
$conn->setPort(5672);
$conn->setLogin('guest');
$conn->setPassword('guest');
$conn->connect();

//创建队列
$q = new AMQPQueue($conn);
$q->setName('queue-name');
$q->declare();

//绑定交换机
$q->bind('exchange-name', 'routing-key');

//消费消息
while (true) {
    $message = $q->get();
    if ($message) {
        echo $message->getBody() . PHP_EOL;
        $q->ack($message->getDeliveryTag());
    }
}

//关闭连接
$conn->disconnect();
?>

2. php-amqp library implementation

php-amqp is the officially provided PHP RabbitMQ library. Compared with the amqp extension, compare Easy to use. Here's a brief introduction to how to use it.

i. Publishing messages

Use AMQPChannel and AMQPExchange classes together to implement message publishing. The following is a basic example:

<?php
//连接RabbitMQ服务器
$conn = new AMQPConnection();
$conn->setHost('localhost');
$conn->setPort(5672);
$conn->setLogin('guest');
$conn->setPassword('guest');
$conn->connect();

//创建通道和交换机
$channel = new AMQPChannel($conn);
$exchange = new AMQPExchange($channel);
$exchange->setName('exchange-name');
$exchange->setType(AMQP_EX_TYPE_DIRECT);
$exchange->declare();

//发布消息
$message = 'Hello World!';
$exchange->publish($message, 'routing-key');

//关闭连接
$conn->disconnect();
?>

ii. Consuming messages

The AMQPQueue class is used in the php-amqp library to implement message consumption. The following is a basic example:

<?php
//连接RabbitMQ服务器
$conn = new AMQPConnection();
$conn->setHost('localhost');
$conn->setPort(5672);
$conn->setLogin('guest');
$conn->setPassword('guest');
$conn->connect();

//创建通道和队列
$channel = new AMQPChannel($conn);
$queue = new AMQPQueue($channel);
$queue->setName('queue-name');
$queue->declare();

//绑定交换机
$queue->bind('exchange-name', 'routing-key');

//消费消息
while (true) {
    $message = $queue->get();
    if ($message) {
        echo $message->getBody() . PHP_EOL;
        $queue->ack($message->getDeliveryTag());
    }
}

//关闭连接
$conn->disconnect();
?>

So far, we have successfully implemented the construction of RabbitMQ PHP SDK.

4. Summary

This article briefly introduces how to implement the open source RabbitMQ SDK through PHP, from building the RabbitMQ environment to installing the PHP AMQP extension to the two ways to implement the SDK. I believe readers Already have a certain understanding and practical ability. In actual development, choosing a suitable SDK can greatly improve development efficiency, allowing us to complete tasks quickly and efficiently.
