Swoole 2.1 Official release, co-op + channel brings new PHP programming mode

This is a creation in Article, where the information may have evolved or changed.

PHP's asynchronous, parallel, high-performance network communications engine Swoole published 2.1.0 versions. The new version provides a new short name API that fully supports the Co-op (coroutine) + channel feature, bringing a new programming model to the PHP language. Swoole 2.1 API Go language, to the Go language development team.

Coroutine

go(function () {    co::sleep(0.5);    echo "hello";});go("test");go([$object, "method"]);

Channel

$chan = new chan(128);$chan->push(1234);$chan->push(1234.56);$chan->push("hello world");$chan->push(["hello world"]);$chan->push(new stdclass);$chan->push(fopen("test.txt", "r+"));while($chan->pop());

Unlike Go language chan , because PHP it is a dynamic language, you can post any type of variable to the channel.

Channel Select

  $c 1 = new Chan (3), $c 2 = new Chan (2); $c 3 = new Chan (2); $c 4 = new Chan (2); $c 3->push (3); $c 3->pus    H (3.1415), $c 4->push (3), $c 4->push (3.1415), Go (function () use ($c 1, $c 2, $c 3, $c 4) {echo "select\n";        for ($i = 0; $i < 1; $i + +) {$read _list = [$c 1, $c 2];        $write _list = [$c 3, $c 4];        $write _list = null;        $result = Chan::select ($read _list, $write _list, 5);        Var_dump ($result, $read _list, $write _list);        foreach ($read _list as $ch) {var_dump ($ch->pop ());        } foreach ($write _list as $ch) {var_dump ($ch->push (666));    } echo "exit\n";    }}); Go (function () use ($c 3, $c 4) {echo "producer\n";    Co::sleep (1);    $data = $c 3->pop ();    echo "pop[1]\n"; Var_dump ($data);}); Go (function () {co::sleep (10);});    Go (function () use ($c 1, $c 2) {co::sleep (1);    $c 1->push ("Resume"); $c 2->push ("Hello");});  

MySQL Client

go(function () {    $db = new Co\MySQL();    $server = array(        'host' => '127.0.0.1',        'user' => 'root',        'password' => 'root',        'database' => 'test',    );    $db->connect($server);    $result = $db->query('SELECT * FROM userinfo WHERE id = 3');    var_dump($result);});

Redis Client

go(function () {    $redis = new Co\Redis;    $res = $redis->connect('127.0.0.1', 6379);    $ret = $redis->set('key', 'value');    var_dump($redis->get('key'));});

Http Client

go(function () {    $http = new Co\Http\Client("www.google.com", 443, true);    $http->setHeaders(function () {            });    $ret = $http->get('/');    var_dump($http->body);});

HTTP2 Client

go(function () {    $http = new Co\Http2\Client("www.google.com", 443, true);    $req = new co\Http2\Request;    $req->path = "/index.html";    $req->headers = [        'host' => "www.google.com",        "user-agent" => 'Chrome/49.0.2587.3',        'accept' => 'text/html,application/xhtml+xml,application/xml',        'accept-encoding' => 'gzip',    ];    $req->cookies = ['name' => 'rango', 'email' => 'rango@swoole.com'];    $ret = $http->send($req);    var_dump($http->recv());});

Other APIs

co::sleep(100);co::fread($fp);co::fwrite($fp, "hello world");co::gethostbyname('www.google.com');

Server-side

$server = new Co\Http\Server('127.0.0.1', 9501);$server->on('Request', function($request, $response) {    $http = new Co\Http\Client("www.google.com", 443, true);    $http->setHeaders(function () {        "X-Power-By" => "Swoole/2.1.0",    });    $ret = $http->get('/');     if ($ret) {        $response->end($http->body);    }    else{        $response->end("recv failed error : {$http->errCode}");    }});$server->start();

SwooleProvides a wide Co\Server range Co\WebSocket\Server Co\Http\Server Co\Redis\Server 4 of classes that support co-processes Server , which can be used in these server programs API .
