如果我们已经将 FCKeditor 和 SyntaxHighlighter 代码高亮插件整合好（参看http://www.cnblogs.com/catprayer/archive/2010/04/24/1719521.html），让我们来看看如何用 SyntaxHighlighter 来实现代码高亮。
1，下载源码包：syntaxhighlighter_2.1.364.zip （http://alexgorbatchev.com/wiki/SyntaxHighlighter），需要注意的是，这个源码包和上面的插件是不一样的。
解压后：
如果以前没有接触过的话，可以参考 "test.html" 来看一下是如何实现的。
2，可以使用 jQuery 及 官方插件 jQuery UI 来做一个好看的页面。
codeHeightLight.php :

让我们再来看看它到底是怎么处理高亮的：
看看它的 InnerHtml：
