真假rewrite
小清新，就是說的SegmentFault blog啊 首先感謝社區經過個人審覈，給我一個平臺。 風格很好，左右分工很好。 之後將會在這裏開博客了。javascript
最近接手一個項目裏面也有僞靜態來工做
分析其原理讓我有點腦大,尤爲是一開始上手的時候沒有手冊，沒有php
*關於wordpress你們都知道他的那個僞靜態，這個程序的僞靜態是用rewrite.php來中轉的，但更明確的是，他把一個比較簡單的處理弄得很複雜，並且猶豫這傢伙並不擅長類處理方式，因而我在處理這個rewrite的時候很不方便，花了一天時間纔將Apache php5.2.17下的路徑重寫搞定，中間還有不少路徑規則，Apache不解析讓我找不着北，但最終調好了。
他的可取之處有兩點一個是使用了__rewrite方法對數據庫中的路徑規則進行解析，固然她在數據庫中寫的那個東西就不咋地了 本想截圖，只能等會了，手機上不了那個網站 等有機會了吧這個截圖在放上來吧 代碼以下，核心就是在$_SEVER[' REQUEST_URI']上，匹配到後就用這個賦值讓瀏覽器識別網址爲僞靜態 另外一個他用的經典部分就是判斷好了以後就用include方法把根目錄下的index.php引用進來，而後在根目錄下的index.php中將class下的index.php包含進來， 在class中的index.php中經過autoload loadlib 等方法加載相關類 能夠說程序邏輯沒有問題，但卻很明顯的不繫統，不條理，讀懂這個程序很難 相比ThinkPHP，這套程序真是不咋地*css
