Swoole Love PHP

今天公司內訓的簡報摘錄。

研究 Swoole 多年，也確實在上線環境正式運行很久且穩定，所以與同事分享點滴與技巧。

除了一點範例程式外，分享著重的是【架構】差異，延伸出去再與 Nginx/PHP, Node 及 Go 進行一些比較。

主要是提出幾個問題，希望引發思考：

➊ 很多人都說 Swoole 快，是哪裡快？(其實我覺得網路上的資訊不夠全面，講得也不一定為真)

➋ 猜想 Nginx/PHP, Swoole, Node, Go 基礎效能比較？還能最佳化嗎？何處著手？

➌ 其他。

36. 36/39 Ref: https://wiki.swoole.com/wiki/page/604.html Coroutine: HTTP Client $httpclient = new Swoole\Coroutine\Http\Client('127.0.0.1', 80); $httpclient->setHeaders(['Host' => "api.mp.qq.com"]); $httpclient->set([ 'timeout' => 1]); $httpclient->setDefer(); $httpclient->get('/'); // to do something $http_res = $httpclient->recv();
37. 37/39 Why not Go(lang)
38. 38/39 Why not Go(lang) ➊ Not most developers in company are familiar with Go(lang). ➋ Not so many Go(lang) developers in Taiwan (future?). ➌ Training time. ➍ Swoole performance is close to Go(lang) in some cases.
