老骨頭先生

因為工作關係，所以這陣子必須和微軟系統周旋，搞得我一個頭兩個大 =_=

先是 Win2003 + Apache + MSSQL 的問題，一直都搞不定 :~

後來決定用在 XP 上，但是原來跑的很順的 XP + Apache + MSSQL 也出了一個問題 !

Unknown():Unable to load dynamic library 'c:\php\extension\php-mssql.dll'-找不到指定的模組.

這問題以前從沒出現過，而且安裝還是同一個程式，所以覺得實在奇怪。
但秉著"電腦這玩意決定沒有靈異現象"的信念，最後終於被我查出來了...

普級的解決方式：
1.檢查 extension_dir = "c:/php/extensions/"
2.設定系統環境變數
3.將 dll copy 到 ％windir％\system32 下

當以上動作都作過時，還是會出現錯誤，以下列表可以幫助我們回答這個問題。
因為 PHP 的 dll 檔依賴某些 dll，所以必須將相關的 dll 給 copy 進去，而 mssql 就是少了 ntwdblib.dll 這個檔。

我發現某些電腦有某些沒有，而有 ntwdblib.dll 這個檔案的皆安裝了 mssql，所以即時你只是想使用 mssql function 連到外部的 mssql，你也必須要有 ntwdblib.dll。
