小清新,就是说的SegmentFault blog啊 首先感谢社区通过我的审核,给我一个平台。 风格很好,左右分工很好。 以后将会在这里开博客了。

最近接手一个项目里面也有伪静态来工作
分析其原理让我有点脑大,尤其是一开始上手的时候没有手册,没有

*关于wordpress大家都知道他的那个伪静态,这个程序的伪静态是用rewrite.php来中转的,但更明确的是,他把一个比较简单的处理弄得很复杂,而且犹豫这家伙并不擅长类处理方式,于是我在处理这个rewrite的时候很不方便,花了一天时间才将Apache php5.2.17下的路径重写搞定,中间还有很多路径规则,Apache不解析让我找不着北,但最终调好了。
他的可取之处有两点一个是使用了__rewrite方法对数据库中的路径规则进行解析,当然她在数据库中写的那个东西就不咋地了 本想截图,只能等会了,手机上不了那个网站 等有机会了吧这个截图在放上来吧 代码如下,核心就是在$_SEVER[' REQUEST_URI']上,匹配到后就用这个赋值让浏览器识别网址为伪静态 另一个他用的经典部分就是判断好了之后就用include方法把根目录下的index.php引用进来,然后在根目录下的index.php中将class下的index.php包含进来, 在class中的index.php中通过autoload loadlib 等方法加载相关类 可以说程序逻辑没有问题,但却很明显的不系统,不条理,读懂这个程序很难 相比ThinkPHP,这套程序真是不咋地*
