You can either do this server-side or client-side. It's not very processor intensive, but if you do it client side (using Javascript) there will be a noticeable lag. Most client side solutions revolve around Google Code's syntax highlighting engine. This seems to be the most popular one: SyntaxHighlighter
您可以在服务器端或客户端执行此操作。它不是非常密集的处理器，但是如果您在客户端（使用 Javascript）执行此操作，则会有明显的延迟。大多数客户端解决方案都围绕着 Google Code 的语法高亮引擎。这似乎是最受欢迎的：SyntaxHighlighter
Server-side solutions tend to be more flexible, especially in the way of defining new languages and configuring how they are highlighted (e.g. colors used). I use GeSHi, which is a PHP solution with a moderately nice plugin for Wordpress. There are also a few libraries built for Java, and even some that are based upon VIM (usually requiring a Perl module to be installed from CPAN).
服务器端解决方案往往更加灵活，尤其是在定义新语言和配置它们的突出显示方式（例如使用的颜色）方面。我使用 GeSHi，这是一个 PHP 解决方案，带有一个相当不错的 Wordpress 插件。还有一些为 Java 构建的库，甚至一些基于 VIM 的库（通常需要从 CPAN 安装 Perl 模块）。
In short: you have quite a few options, what are your criteria? It's hard to make a solid recommendation without knowing your requirements.
简而言之：你有很多选择，你的标准是什么？在不了解您的要求的情况下，很难提出可靠的建议。

I use GeSHi("Generic Syntax Highlighter") on pastebin.com
我在pastebin.com上使用GeSHi（“通用语法荧光笔”）
pastebin has high traffic, so I do cache the results of the transformation, which certainly reduces the load.
pastebin 的流量很高，所以我缓存了转换的结果，这当然减少了负载。

Personally, I prefer offline tools: I don't see the point of parsing the code (particularly large ones) over and over, for each served page, or even worse, on each browser (for JS libraries), because as pointed above, these libraries often lag (you often see raw source before it is formatted).
就我个人而言，我更喜欢离线工具：我没有看到为每个服务页面一遍又一遍地解析代码（尤其是大代码）的意义，甚至更糟的是，在每个浏览器上（对于 JS 库），因为如上所述，这些库经常滞后（您经常在格式化之前看到原始源代码）。
There are a number of tools to do this job, some pointed above. I just use the export feature of my favorite editor (SciTE) because it just respects the choices of color I carefully set up... :-) And it can output XML, PDF, RTF and LaTeX too.
有许多工具可以完成这项工作，上面提到了一些。我只是使用我最喜欢的编辑器 (SciTE) 的导出功能，因为它只尊重我精心设置的颜色选择... :-) 它也可以输出 XML、PDF、RTF 和 LaTeX。

I use google-code-prettify. It is the simplest to set up and works great with all C-style languages.
我使用google-code-prettify。它设置起来最简单，并且适用于所有 C 风格的语言。

Pygmentis a good Python library to generate HTML, RTF, ANSI (terminal-style) or LaTeX code. It supports a large range of languages(C, C++, Lua, Erlang, ...) and you can even write your own output formatter.
Pygment是一个很好的 Python 库，可以生成 HTML、RTF、ANSI（终端样式）或 LaTeX 代码。它支持多种语言（C、C++、Lua、Erlang 等），您甚至可以编写自己的输出格式化程序。

If you are using PHP, you can use GeSHito highlight many different languages. I've used it before and it works quite well. A quick googling will also uncover GeSHi plugins for wordpressand drupal.
如果您使用的是 PHP，您可以使用GeSHi来突出显示许多不同的语言。我以前用过它，效果很好。快速谷歌搜索还会发现用于wordpress和drupal 的GeSHi 插件。
I wouldn't consider highlighting to be CPU intensive unless you are intending to display megabytes of it all at once. And even then, the CPU load would be minimal and your main problem would be transfer speed for it all.
我不会考虑突出显示是 CPU 密集型的，除非您打算一次显示全部兆字节。即便如此，CPU 负载也会很小，您的主要问题将是传输速度。
