php yaf 公司 实例 拓展 框架 突 编写

最近公司换了yaf框架，突然对用c实现php拓展感兴趣了，如果一个功能已经很稳定很成熟而且用的地方很多，那么我们就可以尝试用拓展实现（不一定每种情况都可以写成拓展），写成拓展后就不用每次用都包含一下，工具类直接随php启动加载进内存里。 我这次是把用

 

    最近公司换了yaf框架，突然对用c实现php拓展感兴趣了，如果一个功能已经很稳定很成熟而且用的地方很多，那么我们就可以尝试用拓展实现（不一定每种情况都可以写成拓展），写成拓展后就不用每次用都包含一下，工具类直接随php启动加载进内存里。

    我这次是把用户会话加密类写成了php的拓展，用户类是基于des加密的，主要实现了，

  1. isLogin //判断是否登录
  2. setLogin //就是种个加密的cookie
  3. getUid
  4. getUsername 

我给这个项目起名slime（史莱姆），勇者斗恶龙里的小怪，黏黏的。。。。。。

ok，先来看下php的实现，因为我们是php -> c,所以先看下php的实现，其实就是很普通用户类
