第一步下载：swoole官网下载 swoole-cli-v5.0.3-cygwin-x64.zip 只支持 64 位的系统

第二步解压到指定文件夹：E:\phpstudy_pro\WWW\swoole-cli-v5.0.3-cygwin-x64

第三步设置环境变量：把解压后的文件夹下的 bin 目录路径配置到系统的 Path 环境变量中，确定保存

 

第四步检查安装情况：打开CMD命令行输入：swoole-cli -v，安装成功

第五步：编写简单的TCP服务器代码：TCP.php

1. 服务端：

<?phpclass TCP
{private $server = null;public function __construct(){$this->server = new Swoole\Server('127.0.0.1', 9501);$this->server->set(array('worker_num' => 4,     // 进程数'max_request' => 50,    // 每个进程最大接受请求数));//监听连接进入事件。$this->server->on('Connect', [$this, 'onConnect']);//监听数据接收事件。$this->server->on('Receive', [$this, 'onReceive']);监听连接关闭事件。$this->server->on('Close', [$this, 'onClose']);//启动服务器$this->server->start();}public function onConnect($server, $fd){echo "客户端id: {$fd}连接.\n";}public function onReceive($server, $fd, $reactor_id, $data){$server->send($fd, "发送的数据: {$data}");}public function onClose($server, $fd){echo "客户端id: {$fd}关闭.\n";}}new TCP();

运行：

2. 客户端：

<?phpuse Swoole\Coroutine\Client;
use function Swoole\Coroutine\run;run(function () {$client = new Client(SWOOLE_SOCK_TCP);if (!$client->connect('127.0.0.1', 9501, 0.5)) {echo "connect failed. Error: {$client->errCode}\n";}fwrite(STDOUT, '请输入');$res = fgets(STDIN);$client->send($res);echo $client->recv();$client->close();
});

运行：
