這是以class包裝好的簡繁體轉換的class,
另外需要兩個table檔:
1. http://www.jerry.com.tw/php/big5.map
2. http://www.jerry.com.tw/php/gb.map
程式如下: CCharset.php3

使用範例:
// Designer: Magic Jerry
//====直接轉換文字字串的使用方法========
include("CCharset.php3");
$obj=new CCharset;
$big5="這是一個big5的文字字串";
$tgb =$obj->Big5_Gb($big5);
echo $tgb; //===> $tgb為轉換好的gb碼字串
$tbig5=$obj->Gb_Big5($tgb);
echo $tbig5; // 又轉回來了: big5
//============= ================== =========
?>
//如果直接轉換網頁或是檔案
// 語法http ://your.domain.com.tw/這個程式.php3?http://要轉碼的網頁url或檔案
/ / example: 轉換奇摩首頁
// http://your.domain .com.tw/這個程式.php3?http://www.kimo.com.tw/index.shtml
// 注意:以下寫法如遇到該網頁有使用cookie,例如認證user,可能會被踢回去,login錯誤..
// 為什麼? 想想看...@_@
