- 18. ?Event-driven ? non-blocking I/O ? with Pure PHP ? Native extensions are also available for better performance
- 19. var http = require('http'); http.createServer(function (req, res) { ????res.writeHead(200, {'Content-Type': 'text/plain'}); ????res.end('Hello Worldn'); }).listen(1337, '127.0.0.1'); console.log('Server running at http://127.0.0.1:1337/');

- 23. StreamSelectLoop
- 25. stream_set_blocking($stream, 0) ?ストリ`ムをブロックしない モ`ドにする ?I/O 棋ちがk伏しなくなる
- 26. stream_select() select(2) for PHP
- 27. $ man 2 select
