① GitHub 上有哪些比较有趣的 php 项目
swoole, C扩展实现的PHP异步并行网络通信框架,可以重新定义PHP。过去PHP只能做Web项目,现在有了Swoole。任意服务器端程序都可以用PHP写。swoole_framework,基于swoole扩展开发的一个开发框架 。yaf,C扩展实现的高性能Web开发框架 。php-webim,基于swoole实现的Web即时聊天工具具,支持websocket+http comet长链接推送,可以发送文字内容和图片。
使用PHP代码实现异步框架。如果说swoole是node.js的升级版,react.php就是标准的PHP版本node.js workerman ,类似swoole,不过是纯PHP实现的官网有很多示例项目。底层功能比swoole少一些,但相对简单,应用层面的功能比swoole丰富。phalcon ,俗称尔康框架,与yaf类似也是C扩展开发的高性能Web框架,与yaf相比phalcon提供的功能更多更完善。
可以用近似PHP的一种中间代码写程序,然后自动转为C++,并作为扩展来运行。可以解决PHP语言密集计算性能差的问题。phpdaemon,基于swoole扩展写的异步redis客户端,压测起来性能跟Go语言之类的差不多。
