php+++swoole

Swoole is an open-source PHP extension that provides a high-performance networking framework and coroutine-based concurrency API for PHP developers. It allows developers to write asynchronous, non-blocking, and event-driven PHP applications.

To install Swoole, you can follow these steps:

1. Make sure you have PHP installed on your system. Swoole requires PHP version 7.0 or above.

2. Install the Swoole extension using PECL (PHP Extension Community Library). Run the following command in your terminal:

   pecl install swoole

   This will download and install the Swoole extension.

3. Once the installation is complete, you need to enable the Swoole extension in your PHP configuration. Locate your php.ini file and add the following line:

   extension=swoole.so

4. Save the php.ini file and restart your web server to apply the changes.

After installing Swoole, you can start using its features in your PHP applications. For example, you can create a TCP server, handle HTTP requests, or use Swoole's coroutine API to write asynchronous code.

Here's a simple example of creating a TCP server using Swoole:

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

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

$server->on('receive', function ($server, $fd, $from_id, $data) {
    echo "Received data from client: $data\n";
    $server->send($fd, "Server received: $data");
});

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

$server->start();

This is just a basic introduction to Swoole. It offers many more features and capabilities, such as WebSocket support, process management, and more. You can refer to the official Swoole documentation for more details and examples: https://www.swoole.co.uk/docs
