通过phpize（扩展php扩展模块，建立php外挂模块）：

可以看到swoole.so的位置

配置php.ini

检测swoole安装成功并且php支持swoole

学习swoole需要去翻阅文档， swoole文档

tcp服务端（tcp_server.php）

//创建Server对象，监听 127.0.0.1:9501端口$serv = new swoole_server("127.0.0.1", 9501);$serv->set([    'worker_num' => 4, // worker进程数，cpu 1-4倍    'max_request' => 100,]);/** * 监听连接进入事件 * $fd 客户端连接服务端的唯一标识 * $reactor_id 线程id */$serv->on('connect', function ($serv, $fd, $reactor_id) {    echo "Client: {$fd} - {$reactor_id} - Connect.\n";});//监听数据接收事件$serv->on('receive', function ($serv, $fd, $reactor_id, $data) {    $serv->send($fd, "Server: ".$data);});//监听连接关闭事件$serv->on('close', function ($serv, $fd) {    echo "Client: Close.\n";});//启动服务器$serv->start();

tcp客户端（tcp_client.php）

// 创建tcp客户端$client = new swoole_client(SWOOLE_SOCK_TCP);// 连接tcp服务端if (!$client->connect("127.0.0.1", 9501)) {    echo '连接失败';    exit;}// php clifwrite(STDOUT, '请输入：');$msg = trim(fgets(STDIN));// 发送消息给tcp服务端if (!$client->send($msg)) {    echo '发送消息失败';    exit;}// 接收$result = $client->recv();echo $result;

$server->on('Request', function ($req, $resp) {    echo "hello world";});

class A{    static function test($req, $resp)    {        echo "hello world";    }}$server->on('Request', 'A::Test');$server->on('Request', array('A', 'Test'));

function my_onRequest($req, $resp){    echo "hello world";}$server->on('Request', 'my_onRequest');

class A{    function test($req, $resp)    {        echo "hello world";    }}$object = new A();$server->on('Request', array($object, 'test'));

小技巧：查看开启的worker进程： ps aft | grep tcp_server.php

// 监听所有地址和9501端口$http = new swoole_http_server('0.0.0.0', 9501);// 动静分离配置$http->set([    // 开启静态请求    'enable_static_handler' => true,    // 静态资源目录    'document_root' => '/opt/app/code1/',]);$http->on('request', function ($request, $response) {    // 获取get请求的参数    $param = json_encode($request->get);    // 设置cookie    $response->cookie('name', 'ronaldo', time() + 1800);    // 输出到页面    $response->end("<h1>Hello Swoole - {$param}</h1>");});// 开启http服务$http->start();

websocket服务端（websocket_server.php）

// 监听所有地址和9502端口$server = new swoole_websocket_server('0.0.0.0', 9502);// 动静分离配置$server->set([    // 开启静态请求    'enable_static_handler' => true,    // 静态资源目录    'document_root' => '/opt/app/swoole/websocket',]);$server->on('open', function ($server, $request) {    echo "server：handshake success with fd - {$request->fd}\n";});$server->on('message', function ($server, $frame) {    echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";    $server->push($frame->fd, "this is server");});$server->on('close', function ($server, $fd) {    echo "client - {$fd} - close\n";});$server->start();

websocket客户端 （websockt_client.html）

// 创建websocket实例        var websocketURL = "ws://www.rona1do.top:9502";        var websocket = new WebSocket(websocketURL);        // 实例化对象的onopen属性        websocket.onopen = function (ev) {            websocket.send("hello-websocket");            console.log("connect-swoole-success");        }        // 实例化对象的onmessage属性，接收服务端返回的数据        websocket.onmessage = function (ev) {            console.log("websockect-server-return-data：" + ev.data);        }        // close        websocket.onclose = function (ev) {            console.log("close");        }

class WebSocket {    const HOST = '0.0.0.0';    const PORT = 9502;    private $ws = null;    function __construct()    {        $this->ws = new swoole_websocket_server(self::HOST, self::PORT);        $this->ws->on('open', [$this, 'onOpen']);        $this->ws->on('message', [$this, 'onMessage']);        $this->ws->on('close', [$this, 'onClose']);        $this->ws->start();    }    // 监听websocket连接事件    function onOpen($server, $request) {        echo "server: handshake success with fd{$request->fd}\n";    }    // 监听websocket消息接收事件    function onMessage($server, $frame) {        echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";        $server->push($frame->fd, "this is server");    }    // 监听客户端关闭事件    function onClose($server, $fd) {        echo "Client：{$fd} closes\n";    }}

onTask：在task_worker进程内被调用。worker进程可以使用swoole_server_task函数向task_worker进程投递新的任务。当前的Task进程在调用onTask回调函数时会将进程状态切换为忙碌，这时将不再接收新的Task，当onTask函数返回时会将进程状态切换为空闲然后继续接收新的Task。

onFinish：当worker进程投递的任务在task_worker中完成时，task进程会通过swoole_server->finish()方法将任务处理的结果发送给worker进程。

// 创建tcp客户端$client = new swoole_client(SWOOLE_SOCK_TCP);// 连接tcp服务端if (!$client->connect("127.0.0.1", 9501)) {    echo '连接失败';    exit;}// php clifwrite(STDOUT, '请输入：');$msg = trim(fgets(STDIN));// 发送消息给tcp服务端if (!$client->send($msg)) {    echo '发送消息失败';    exit;}// 接收$result = $client->recv();echo $result;0
