PHP实现的通用语法高亮显示工具GeSHi

 GeSHi - Generic Syntax Highlighter，一个用PHP写的通用语法高亮显示工具。这儿有Demo可以看看。
GeSHi started as an idea to create a generic syntax highlighter for the phpBB
forum system, but has been generalised to this project. GeSHi aims to
be a simple but powerful highlighting class, with the following goals:

• Support for a wide range of popular languages


• Easy to add a new language for highlighting


• Highly customisable output formats

GeSHi
aims to do this all as quickly as possible. Many customisable features
of GeSHi facilitate speed increases, and you can easily find a balance
between the amount of highlighting done and the speed in which it is
done.

GeSHi supports PHP5 and Windows, and has even been used to highlight
code on ASP pages. Numerous blogs, wikis and forums use GeSHi,
including Dokuwiki, Mambo, phpBB and WikkiWiki.
