How to Enable ServBay's Built-in Swoole Module

As a powerful integrated web development tool, ServBay comes with a built-in Swoole module, and its activation process is very simple. Swoole, as a high-performance PHP asynchronous network communication engine, has a modular design that allows developers to easily build efficient web applications and services.

Introduction to the Swoole Framework

Swoole is an open-source high-performance network communication engine designed specifically for PHP. By providing an asynchronous, parallel network programming model, it significantly enhances the performance and scalability of PHP applications. Swoole supports multiple protocols, including HTTP, WebSocket, TCP, and UDP, enabling developers to build various types of network applications.

Key Features

1. High Performance: Swoole uses asynchronous IO, multi-threading, and coroutine technologies to significantly increase the throughput and response speed of PHP applications.
2. Low Latency: Swoole's asynchronous programming model reduces blocking operations, lowering request processing latency.
3. Rich Features: Swoole provides features such as coroutines, timers, process management, and memory management, meeting the needs of high concurrency and high performance.
4. Easy to Extend: Swoole's modular design and rich API allow developers to flexibly extend application functionalities.
5. Multi-Protocol Support: Swoole supports multiple communication protocols such as HTTP, WebSocket, TCP, and UDP, suitable for various scenarios.

ServBay Built-in Swoole Module Version

ServBay supports multiple PHP versions and preinstalls the corresponding Swoole module for each version. Specific versions are as follows:

• PHP 5.6 - 8.4: Swoole 5.1.2

How to Enable Swoole Module

By default, the Swoole module is disabled. Enabling the Swoole module is very simple, requiring only a modification to the configuration file for the respective PHP version. The detailed steps are as follows:

Step 1: Locate the Configuration File

First, navigate to the conf.d directory for the corresponding PHP version. For example, to enable the Swoole module for PHP 8.3, we need to edit the following file:

/Applications/ServBay/etc/php/8.3/conf.d/swoole.ini

Step 2: Edit the Configuration File

Open the swoole.ini file and uncomment the following line:

[Swoole]
; Uncomment the following line to enable Swoole
extension = swoole.so

Step 3: Restart PHP Service

In ServBay’s service management panel, restart the corresponding PHP service. For example, restart the PHP 8.3 service. Once the restart is complete, the Swoole module will be successfully loaded.

Verify if the Swoole Module is Successfully Loaded

You can verify if the Swoole module is successfully loaded by creating a simple PHP file. In the web server's root directory, create a phpinfo.php file with the following content:

<?php
phpinfo();
?>

Visit https://servbay.host/phpinfo.php, and look for the relevant Swoole information on the PHP info page. If you see the Swoole-related information, the module has been successfully loaded.

Usage Example

After enabling the Swoole module, you can use Swoole in your PHP code to create high-performance web applications. Below is a simple example demonstrating how to use Swoole to create a basic HTTP server:

Example Code

1. Create Project Directory Structure

my-swoole-app/
├── public/
│   └── index.php
├── logs/
└── vendor/
    └── autoload.php

2. Front Controller: public/index.php

<?php

use Swoole\Http\Server;
use Swoole\Http\Request;
use Swoole\Http\Response;

// Create an HTTP server
$server = new Server("0.0.0.0", 9501);

// Listen to request events
$server->on("request", function (Request $request, Response $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello ServBay!");
});

// Start the server
$server->start();

3. Run the Server Ensure that the Swoole module is enabled, then run the following command in the command line to start the server:

php public/index.php

After the server starts, visit http://localhost:9501 in your browser, and you will see the output "Hello ServBay!".

Conclusion

ServBay provides an easy way to manage and enable the Swoole module. Through simple configuration and restart operations, developers can quickly enable the Swoole module in different PHP versions, thus fully utilizing its high performance and rich functionalities to improve the development efficiency of web applications and services. Swoole’s high performance, low latency, and rich features make it an excellent choice for building efficient and scalable network applications.
