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
//=====================================================
// 程式員: Magic Jerry
//
// function Big5_Gb($str) => big5轉GB for string
// function Gb_Big5($str) => GB轉Big5 for string
//=====================================================
class CCharset {
var $gb_map="gb.map"; //如果要放到別的路徑,要加上完整路徑
var $big5_map="big5.map"; //例如 ="/home/table/gb.map
var $dep_char = 127;
//-----------------------------------------------------------------
function cbig5_gb($str,$fd) {
$c=ord(substr($str,0,1));

}

使用範例:
// Designer: Magic Jerry
//====直接轉換文字串 的使用方法========
include("CCharset.php3");
$obj=new CCharset;
$big5="這是一個big5的文字串";
$tgb=$obj->Big5_Gb($big5);
echo $tgb; //===> $tgb為轉換好的gb碼字串
$tbig5=$obj->Gb_Big5($tgb);
echo $tbig5; // 又被轉回來了: 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,login錯誤..
// 為什麼? 想想看吧... @_@
include("CCharset.php3");
$file=$QUERY_STRING;
$fcontents = join( '', file( "$file" ) );
$fcontents=str_replace("","
$code=new CCharset;
$gb=$code->Big5_Gb($fcontents);
echo $gb;
?>
範例:
if($func=="charset") {
setcookie("CHAR_GB",$GB,time()+ 31536000);
$t=time();
$url="http://".$HTTP_HOST.$PHP_SELF."?".$QUERY_STRING;
$url=str_replace("?func=charset&GB=1","", $url);
$url=str_replace("?func=charset&GB=0","", $url);

//echo $url;

exit;
}
//phpinfo();
