How much does swoole support php? (Installation tutorial sharing)

Swoole (pronounced: Swō-lē) is a fully asynchronous, high-performance PHP network communication engine. It implements multiple protocols such as TCP, UDP, HTTP, WebSocket, MQTT, etc., and provides a fully asynchronous network programming interface, allowing PHP programs to easily construct distributed, high-concurrency, and highly reliable network applications.

Before developing Swoole, we need to confirm which PHP versions it supports. This article will introduce the PHP versions supported by Swoole and how to install and use Swoole.

1. PHP versions supported by Swoole

1. PHP 7.0 - PHP 7.2

Swoole was originally developed for PHP7. Therefore, PHP7.0 to PHP7.2 are the most commonly used versions of Swoole. If your project is developed based on PHP7.0 - PHP7.2, then Swoole will be a very good choice.

2. PHP 7.3 - PHP 7.4

Swoole is already compatible with PHP7.3 and higher versions. If your project is developed based on PHP7.3 or higher, then you can use Swoole to implement highly concurrent, distributed, and highly reliable network applications.

3. PHP 5.5 - PHP 5.6

Although Swoole is developed for PHP7, it is also compatible with PHP5.5 and PHP5.6 versions. If your project is developed based on PHP5.5 - PHP5.6, then you can also use Swoole.

2. Install Swoole

1. Compile and install

In the Linux environment, we can directly compile and install Install Swoole, the specific steps are as follows:

• Download Swoole source code

• Unzip the source code:

tar zxvf swoole-x.y.z.tar.gz

• Enter the source code directory:

cd swoole-x.y.z

• Execute the configure command:

./configure

• Execute the make command:

make

• Execute the make install command:

make install

2. Pecl installation

Pecl installation is another installation method of Swoole, which can save the compilation process. The specific steps are as follows:

• Execute command:

pecl install swoole

3. Use Swoole

1. Create a TCP server

Creating a TCP server using Swoole is very simple and only requires a few lines of code:

$server = new \Swoole\Server('127.0.0.1', 9501);

$server->on('connect', function ($server, $fd) {
    echo "Client: Connect.\n";
});

$server->on('receive', function ($server, $fd, $reactor_id, $data) {
    $server->send($fd, "Server: " . $data);
});

$server->on('close', function ($server, $fd) {
    echo "Client: Close.\n";
});

$server->start();

2. Create HTTP server

Creating an HTTP server using Swoole is also very simple. It only requires a few lines of code:

$http = new \Swoole\Http\Server("127.0.0.1", 9501);

$http->on('request', function (\Swoole\Http\Request $request, \Swoole\Http\Response $response) {
    $response->header('Content-Type', 'text/html; charset=utf-8');
    $response->end("<h1>Hello Swoole. #" . rand(1000, 9999) . "</h1>");
});

$http->start();

4. Summary

Swoole is a very excellent PHP network communication engine, which supports PHP7.0 - PHP7.4 and PHP5.5 - PHP5.6 versions. We can install Swoole through compilation and installation or Pecl installation. It is very simple to use Swoole to create TCP server and HTTP server. In view of its high performance and high concurrency characteristics, Swoole is used and recognized by more and more PHP developers.
