6. var http = require('http'); var server = new http.Server(); server.on('request', function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res.end('Hello World\n'); }); server.listen(1337, '127.0.0.1');
8. $server = stream_socket_server('tcp://127.0.0.1:1337'); while ($conn = stream_socket_accept($server, -1)) { fwrite($conn, "HTTP/1.1 200 OK\r\n"); fwrite($conn, "Content-Length: 3\r\n\r\n"); fwrite($conn, "Hi\n"); fclose($conn); }
9. $s=stream_socket_server('tcp://[::1]:81'); while($c=stream_socket_accept($s,-1)) fwrite($c,"HTTP/1.1 200 OK\r\nContent-Length: 2\r\n\r\nHi");
10. stream_select
11. $readable = $read ?: null; $writable = $write ?: null; $except = null; if (stream_select($readable, $writable, $except, 1)) { if ($readable) { foreach ($readable as $stream) { ... } } if ($writable) { foreach ($writable as $stream) { ... } } }
13. Event-driven, non-blocking I/O with PHP.
14. $loop = React\EventLoop\Factory::create(); $socket = new React\Socket\Server($loop); $http = new React\Http\Server($socket, $loop); $http->on('request', function ($req, $rep) { $rep->writeHead(); $rep->end("Hello World!\n"); }); $socket->listen(8080); $loop->run();

21. $foo->get(function ($bar) { $bar->get(function ($baz) { $baz->get(function ($bazinga) { $bazinga->get(function () { throw new FuckItException(); }); }); }); });
22. async API (escaping callback hell)
23. React/Async
24. use React\Async\Util as Async; Async::waterfall([ function ($callback) use ($foo) { $foo->get($callback); }, function ($bar, $callback) { $bar->get($callback); }, function ($baz, $callback) { $baz->get($callback); }, function ($bazinga, $callback) { $bazinga->get($callback); }, function ($callback) { throw new FuckItException(); } ]);
25. React/Promise
26. $dns ->resolve('igor.io') ->then(function ($ip) { echo "Host: $ip\n"; });
27. $promise ->then('doStuff') ->then('doMoreStuff') ->then('explosion') ->then(null, function ($e) { echo "[Error] {$e->getMessage()}\n"; });
