Use Swoole to develop a high-performance logistics distribution management system

Swoole is a high-performance network communication engine based on PHP, which can be used to develop high-performance server-side application. In logistics distribution management systems, high-performance network communication is very important because the system needs to handle a large amount of data transmission and concurrent requests. This article will introduce how to use Swoole to develop a high-performance logistics distribution management system and provide corresponding code examples.

1. Install the Swoole extension

First, you need to install the Swoole extension. You can install the Swoole extension through the following command:

pecl install swoole

After the installation is complete, add the following line in the php.ini file:

extension=swoole.so

Then restart the PHP service.

2. Create a server

Next, we need to create a Swoole server. You can use the following code example to create a basic Swoole server:

<?php

$server = new SwooleServer('0.0.0.0', 9501);
$server->on('connect', function ($server, $fd) {
    echo "Client {$fd} connected
";
});
$server->on('receive', function ($server, $fd, $from_id, $data) {
    echo "Received data from client {$fd}: {$data}
";
    $server->send($fd, "Server received: {$data}
");
});
$server->on('close', function ($server, $fd) {
    echo "Client {$fd} closed
";
});

$server->start();

The above code creates a Swoole server listening at the 0.0.0.0:9501 address and defines three event callback functions: connect, receive, and close . When the client connects to the server, the connect event callback function is triggered; when the server receives client data, the receive event callback function is triggered; when the client closes the connection, the close event callback function is triggered.

3. Processing business logic

In the logistics distribution management system, a large amount of data transmission and concurrent requests need to be processed. In order to improve the performance of the system, you can use the coroutine and asynchronous IO features provided by Swoole.

The following is a simple example of logistics order processing:

<?php

$server = new SwooleServer('0.0.0.0', 9501);
$server->on('connect', function ($server, $fd) {
    echo "Client {$fd} connected
";
});
$server->on('receive', function ($server, $fd, $from_id, $data) {
    echo "Received data from client {$fd}: {$data}
";

    // 处理订单逻辑
    go(function () use ($fd, $data) {
        // 模拟处理订单的耗时操作
        sleep(2);

        // 返回订单处理结果给客户端
        $server->send($fd, "Order processed: {$data}
");
    });
});
$server->on('close', function ($server, $fd) {
    echo "Client {$fd} closed
";
});

$server->start();

The above code uses Swoole's coroutine feature in the receive event callback function, placing the order processing logic in a coroutine in execution. This enables concurrent processing of multiple order requests and improves system performance and response speed.

4. Use WebSocket to implement real-time message push

In the logistics distribution management system, real-time message push is a very important function. You can use Swoole's WebSocket feature to implement real-time message push.

The following is an example of using Swoole WebSocket to implement real-time message push:

<?php

$server = new SwooleWebSocketServer('0.0.0.0', 9501);
$server->on('open', function ($server, $request) {
    echo "Client {$request->fd} connected
";
});
$server->on('message', function ($server, $frame) {
    echo "Received message from client {$frame->fd}: {$frame->data}
";

    // 处理消息逻辑
    go(function () use ($server, $frame) {
        // 模拟处理消息的耗时操作
        sleep(2);

        // 返回消息处理结果给客户端
        $server->push($frame->fd, "Message processed: {$frame->data}
");
    });
});
$server->on('close', function ($server, $fd) {
    echo "Client {$fd} closed
";
});

$server->start();

The above code creates a WebSocket server and processes the message logic in the message event callback function. Using Swoole's coroutine feature, you can process multiple message requests concurrently and push the processing results to the client in real time.

Summary:

This article introduces how to use Swoole to develop a high-performance logistics distribution management system. By using Swoole's asynchronous IO and coroutine features, system performance and concurrent processing capabilities can be improved. I hope this article will be helpful to developers who are developing logistics distribution management systems.
