DZ论坛核心代码分析计划--核心文件common.inc.php篇
上一篇：DZ论坛核心代码分析-核心文件global.func.php篇
这个文件是DZ的核心大脑级文件。
真正分析起来，其实内容并不多。大多是条件判断和指挥类的语句。引入大量文件。
理解这个文件可以更好的理解整个DZ的论坛是如何运作的。几乎每个页面都引入了这个文件的。
说实话，越往后面看我头越大。。。大量的多层3维条件判断。。嘿嘿，不知道说错没，就是?:这种类型的。有的镶嵌了4层之多。头晕啊。不过大致完成了。
这个文件最值得学习的是其对安全性的重视和处理。。
下面先上写好注释的文件
其他文件整理后随后发上来。不过这个足够说明很多东西了。
写得不对的地方望各位高手指出
本来这一部分我打算我全部搞完了再发上来更新。但是。。。下午分析DZ的缓存机制代码头都搞晕了。就去搞SVN了。现在已经能够提供SVN下载。
为什么把这一楼更新了而又不发放下载。是因为这一部分还没完成。SVN中有今天3个分析的文件可供参看
