基于mysql的bbs设计（五）_PHP
6。bbsd和cq66服务器端改造
bbsd中，关于用户的模块应该比较好改，只要将写.PASSWD文件的操作换为
操作数据库的UserManage类的成员函数即可，但可能要先判断什么数据更改，
要调用哪个函数。并发操作的一致性，则由数据库的加锁功能保证，mysql应该
支持这种的锁吧。文章方面可能比较麻烦，也是将原来对文件的操作转换成操作
数据库的BoardManage类的成员函数即可。
cq66模式应该比较好改动，可能就是原来取文章的协议要变化一下。取文章
标题的时候，同时也将文章的长度发送过去，然后客户端可以根据显示区的大小，
逐步请求文章的内容，请求文章的时候要给出请求的范围。
关于系统模块层，可能做成so的形式会不会较好，（so是不是相当于dll，
容不容易做的，有没有必要？），同时系统模块层应不应该保存一些局部数据呢？
还是做成公用函数一样的接口呢？回想UserManage类，可能没必要区分特权指令，
所有操作都要提供操作对象的id，而权限检查交到上面的服务层来完成？
7。初步测试计划
要测试，等先要把东西做出来，要做东西，先要有别的东西。。。。。
首先将167系统装好，配好mysql，然后学学mysql的 C API 接着建好表，
要做这个计划，先要将短学期的5000行代码写完，然后是复习考研，复习之余将编译器作业作好，再有时间而且没有mm来找我，就可以开始做了。。。。。
