初识PHP中的Swoole,初识PHPSwoole

Swoole是一种PHP高级Web开发框架,框架不是为了提升网站的性能,是为了提升网站的开发效率。最少的性能损耗,换取最大的开发效率。利用Swoole框架,开发一个复杂的Web功能,可以在很短的时间内完成。

官方定义:

Swoole:重新定义PHP

PHP的异步、并行、高性能网络通信引擎,使用纯C语言编写,提供了PHP语言的异步多线程服务器,异步TCP/UDP网络客户端,异步MySQL,异步Redis,数据库连接池,AsyncTask,消息队列,毫秒定时器,异步文件读写,异步DNS查询。 Swoole内置了Http/WebSocket服务器端/客户端、Http2.0服务器端。

Swoole可以广泛应用于互联网、移动通信、企业软件、云计算、网络游戏、物联网、车联网、智能家居等领域。 使用PHP+Swoole作为网络通信框架,可以使企业IT研发团队的效率大大提升,更加专注于开发创新产品。

swoole 扩展安装及案例来源:http://wiki.swoole.com/wiki/page/6.html

简单案例:

<&#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";
}
}
// 启动服务器
$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, "请输入消息:");
$msg = trim(fgets(STDIN));
$this->client->send($msg);
}
}
$client = new Client();
$client->connect(); 

分别打开两个终端输入:php server.php  php client.php 即可看到效果!
