分析一个成功的代码是学习PHP的一种非常有效的方式,通过借鉴,比较,会让自己的编程技巧更加的丰富,也能了解到很多自己在编程中有可能忽略的细节.
所以默默发起了这个代码分析计划,因为默默工作太忙,一个人来分析Discuz的代码需要很长的时间,所以想让大家也参与进来,一起分析一下Discuz的代码,从中吸取有用的知识,并且为自己所用.
Disucuz的include 目录下的 common.inc.php是Discuz的核心文件,很多的东西都是由它来调度的,所以从它开始分析是最适合的.
分析要求:请参考我的代码注释方式(或推荐一种更合理的注释方式)进行分析,分析的时候一定要详细,要让读者明白这段代码到底会产生什么效果,不能只是一句话了事.
请跟帖把自己的分析结果以注释+代码的方式发布出来,经过我审核通过以后会加入到顶楼这个帖子的代码中,当代码全部分析完毕之后,将会把这个文件打包让大家下载到电脑慢慢的研究.

为什么要使用传址而不是传值方式？
要点：在变量前加 & 符号既是传址

$b=$a;
$b++;
echo "b=".$b." a=".$a; //显示：b=2 a=1 可以看到 b变了，而a 却还是没变
