如何使PHP扩展 [英] How to make a PHP extension

问题描述

我知道你可以在技术上刚刚通过的PHP文件，并使用 require_once 让PHP扩展。

I know you can technically make PHP extension just by making a PHP file and using require_once.

但是，如果你写了C或C ++的扩展，将优化性能。

But would it optimize the performance if you wrote an extension in C or C++.

如果是这样，你会如何做一个你好世界是什么？

If so, how would you make a "hello-world" for that?

推荐答案

您可以将单独的C / C ++程序到你的PHP站点只需执行它和输出传递到浏览器。至于真正的操作系统间，它不值得你花时间写包含站点特定功能的库。这简直就不是做，除了与其他现有库（MySQL的，ImageMagick的，等等）进行连接。

You can incorporate a stand-alone C/C++ program into your PHP site simply by executing it and passing the output to the browser. As far as truly inter-operating, it's not worth your time to write a library containing site-specific functionality. This simply isn't done except to interface with other existing libraries (MySQL, imagemagick, etc).

对于Web编程是不一样的应用开发。在更快语言写他们优化您的code位（类似于写你的C汇编++程序小，紧循环位）是不值得的开发时间。你就要去易于维护的保持你的应用程序更好，这就是为什么脚本语言主宰网络。

Programming for the web isn't like application development. Optimizing bits of your code by writing them in "faster" languages (analogous to writing small, tight looping bits of your C++ program in assembly) isn't worth the development time. You're better off keeping your application easily maintainable, this is why scripting languages dominate the web.
