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(IOT)、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。

HttpServer
$serv = new swoole_http_server("127.0.0.1", 9502);

$serv->on('Request', function($request, $response) {
    var_dump($request->get);
    var_dump($request->post);
    var_dump($request->cookie);
    var_dump($request->files);
    var_dump($request->header);
    var_dump($request->server);

    $response->cookie("User", "Swoole");
    $response->header("X-Server", "Swoole");
    $response->end("<h1>Hello Swoole!</h1>");
});

$serv->start();
WebSocket Server
$serv = new swoole_websocket_server("127.0.0.1", 9502);

$serv->on('Open', function($server, $req) {
    echo "connection open: ".$req->fd;
});

$serv->on('Message', function($server, $frame) {
    echo "message: ".$frame->data;
    $server->push($frame->fd, json_encode(["hello", "world"]));
});

$serv->on('Close', function($server, $fd) {
    echo "connection close: ".$fd;
});

$serv->start();
TCP Server
$serv = new swoole_server("127.0.0.1", 9501);
$serv->set(array(
    'worker_num' => 8,   //工作进程数量
    'daemonize' => true, //是否作为守护进程
));
$serv->on('connect', function ($serv, $fd){
    echo "Client:Connect.\n";
});
$serv->on('receive', function ($serv, $fd, $from_id, $data) {
    $serv->send($fd, 'Swoole: '.$data);
    $serv->close($fd);
});
$serv->on('close', function ($serv, $fd) {
    echo "Client: Close.\n";
});
$serv->start();
TCP Client
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);
//设置事件回调函数
$client->on("connect", function($cli) {
    $cli->send("hello world\n");
});
$client->on("receive", function($cli, $data){
    echo "Received: ".$data."\n";
});
$client->on("error", function($cli){
    echo "Connect failed\n";
});
$client->on("close", function($cli){
    echo "Connection close\n";
});
//发起网络连接
$client->connect('127.0.0.1', 9501, 0.5);
Async-IO
$fp = stream_socket_client("tcp://127.0.0.1:80", $code, $msg, 3);
$http_request = "GET /index.html HTTP/1.1\r\n\r\n";
fwrite($fp, $http_request);
swoole_event_add($fp, function($fp){
    echo fread($fp, 8192);
    swoole_event_del($fp);
    fclose($fp);
});
swoole_timer_after(2000, function() {
    echo "2000ms timeout\n";
});
swoole_timer_tick(1000, function() {
    echo "1000ms interval\n";
});
Task
$serv = new swoole_server("127.0.0.1", 9502);
$serv->set(array('task_worker_num' => 4));
$serv->on('Receive', function($serv, $fd, $from_id, $data) {
    $task_id = $serv->task("Async");
    echo "Dispath AsyncTask: id=$task_id\n";
});
$serv->on('Task', function ($serv, $task_id, $from_id, $data) {
    echo "New AsyncTask[id=$task_id]".PHP_EOL;
    $serv->finish("$data -> OK");
});
$serv->on('Finish', function ($serv, $task_id, $data) {
    echo "AsyncTask[$task_id] Finish: $data".PHP_EOL;
});
$serv->start();
