How to Enable the Built-in Swoole Module in ServBay

As a powerful integrated web development tool, ServBay includes the Swoole module, which is very easy to enable. Swoole is a high-performance PHP asynchronous network communication engine whose modular design 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 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 construct various types of network applications.

Main Features

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

Swoole Module Version in ServBay

ServBay supports multiple PHP versions and comes with pre-installed Swoole modules for each version. Specific versions include:

• PHP 5.6 - 8.4: Swoole 5.1.2

How to Enable the Swoole Module

By default, the Swoole module is disabled. The steps to enable the Swoole module are straightforward: simply navigate to Language - PHP, select the PHP version you want to enable the module for, such as PHP 8.4, click Extensions on the right, then toggle the switch on the left of the Swoole module, and save.

Users can also manually open or modify the module configuration, with the following detailed steps:

Step 1: Locate the Configuration File

First, locate the conf.d directory for the corresponding PHP version. For example, to enable the Swoole module for PHP 8.3, you 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

Restart the corresponding PHP service using ServBay's service management panel. For example, restart the service for PHP 8.3. Once restarted, the Swoole module will be successfully loaded.

Verify if the Swoole Module is Loaded Successfully

You can verify whether the Swoole module has loaded successfully by creating a simple PHP file. Create a phpinfo.php file in the web server's root directory with the following content:

<?php
phpinfo();
?>

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

Example Usage

After enabling the Swoole module, you can use Swoole in your PHP code to create high-performance web applications. Here 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 HTTP server
$server = new Server("0.0.0.0", 9501);

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

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

3. Run the Server Ensure 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, you can access http://localhost:9501 in your browser, and you will see the output "Hello ServBay!".

Conclusion

ServBay provides a convenient 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, taking full advantage of its high performance and rich features to enhance the development efficiency of web applications and services. Swoole's high performance, low latency, and abundant features make it an excellent choice for building efficient and scalable network applications.
