Swoole is a PHP advanced web development framework. The framework is not to improve the performance of the website, but to improve the development efficiency of the website. Minimum performance loss in exchange for maximum development efficiency. Using the Swoole framework, developing a complex web function can be completed in a very short time.

Official definition:

Swoole: Redefines PHP

PHP’s asynchronous, parallel, high-performance network communication engine, written in pure C language, provides asynchronous multi-threaded server of PHP language, asynchronous TCP/UDP Network client, asynchronous MySQL, asynchronous Redis, database connection pool, AsyncTask, message queue, millisecond timer, asynchronous file reading and writing, asynchronous DNS query. Swoole has built-in Http/WebSocket server/client and Http2.0 server.

Swoole can be widely used in the Internet, mobile communications, enterprise software, cloud computing, online games, Internet of Things, Internet of Vehicles, smart homes and other fields. Using PHP+Swoole as the network communication framework can greatly improve the efficiency of the enterprise IT R&D team and focus more on developing innovative products.

swoole extension installation and case source: http://wiki.swoole.com/wiki/page/6.html

Simple case:

<&#63;php
class Server
{
private $serv;
public function __construct()
{
$this->serv = new swoole_server("0.0.0.0", 9501);
$this->serv->set(array(
'worker_num' => 8,
'daemonize' => false,
'max_request' => 10000,
'dispatch_mode' => 2,
'debug_mode' => 1
));
$this->serv->on('Start', array($this, 'onStart'));
$this->serv->on('Connect', array($this, 'onConnect'));
$this->serv->on('Receive', array($this, 'onReceive'));
$this->serv->on('Close', array($this, 'onClose'));
$this->serv->start();
}
public function onStart($serv)
{
echo "Start\n";
}
public function onConnect($serv, $fd, $from_id)
{
$serv->send($fd, "Hello {$fd}!");
}
public function onReceive(swoole_server $serv, $fd, $from_id, $data)
{
echo "Get Message From Client {$fd}:{$data}\n";
}
public function onClose($serv, $fd, $from_id)
{
echo "Client {$fd} close connection\n";
}
}
// 啟動服務(wù)器
$server = new Server(); 
<&#63;php
class Client
{
private $client;
public function __construct()
{
$this->client = new swoole_client(SWOOLE_SOCK_TCP);
}
public function connect()
{
if (!$this->client->connect("127.0.0.1", 9501, 1)) {
echo "Error: {$fp->errMsg}[{$fp->errCode}]\n";
}
$message = $this->client->recv();
echo "Get Message From Server:{$message}\n";
fwrite(STDOUT, "請輸入消息：");
$msg = trim(fgets(STDIN));
$this->client->send($msg);
}
}
$client = new Client();
$client->connect(); 

Open two terminals respectively and enter: php server.php　php client.php to see the effect!

Swoole function introduction

includes the following special functions:

1. ORM-like data query, providing SQL wrapper to seamlessly combine MySQL's SQL with PHP's Array, session, and Cache.

2. App MVC layered structure, effective program structure layering, improves program maintainability and scalability, achieves low coupling, and is developed based on interfaces.

3. Integrate a large number of practical functions, such as convenient database operations, template operations, cache operations, system configuration, form processing, paging, data calling, dictionary operations, upload processing, content editing, debugging, etc.

4. Template-data reflection system can directly call data in the template and provide many tags. However, there is no need to modify the program. Just modify the template to realize various updates and maintenance of the website.

A few other functions

1. Swoole contains a large number of classes and provides numerous functional extensions. Basically, most of the functional classes that can be used in web development can be found in the Swoole framework.

2. Swoole has a plug-in system, Fckeditor, Adodb, pscws Chinese word segmentation, Chinese full-text indexing system, the latest Key-Value database idea, TokyoTyrant, which can infinitely expand the functions of the framework.

The above introduces the Swoole in PHP for the first time, including the content of wool and php. I hope it will be helpful to friends who are interested in PHP tutorials.
