簡繁体转换的class_PHP教程

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

//============= = =======================================

//
// 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));
$x=ord(substr($str, 1,1 ));
$address=(($c-160)*510) ($x-1)*2;
fseek($fd, $address);
$hi=fgetc ($fd );
$lo=fgetc($fd);
return "$hi$lo";
}

function cgb_big5($str,$fd) {
$cc =ord(substr($str,0,1));
$x=ord(substr($str,1,1));
$address=(($c-160)* 510) ( $x-1)*2;
fseek($fd, $address);
$hi=fgetc($fd);
$lo=fgetc($fd);
return "$ hi$lo";
}

//------------------------------ --- --------------------------------
function Big5_Gb($str) {
$fd = fopen ( $this->gb_map, "r");
$str=str_replace("charset=big5","charset=gb2312", $str);
$outstr="";
for($ i=0;$i$ch=ord(substr($str,$i,1));
if($ch > $this->dep_char ) {
$outstr.=$this->cbig5_gb(substr($str,$i,2),$fd);
$i ;

} else {
$outstr .=substr($str,$i,1);
}
}
fclose ($fd);
return $outstr;
}
//---- ------------------------------------------- ------- -----------
function Gb_Big5($str) {
$fd = fopen ($this->big5_map, "r");
$str=str_replace("charset =gb2312","charset=big5", $str);
$outstr="";
for($i=0;$i$ ch=ord(substr($str,$i,1));
if($ch > $this->dep_char) {
$outstr.=$this ->cgb_big5(substr($str,$ i,2),$fd);
$i ;

} else {
$outstr.=substr($str,$i, 1);
}
}
fclose ($fd);
return $outstr;

}

}
?>

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...@_@
include("CCharset. php3");
$file=$QUERY_STRING;
$fcontents = join( '', file( "$file" ) );
$fcontents=str_replace("","< ;head>", $fcontents);
$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);
$url=str_replace("&func=charset&GB=1","", $url);
$url=str_replace("&func=charset&GB=0","", $url);
//echo $url;
//echo "SET to Charset = $CHAR_GB";
$t =time();
echo "

";

exit;
}
//phpinfo();
if($CHAR_GB==1 && !$istran ) {
include("CCharset.php3");
if(strlen($QUERY_STRING)) $url ="http://".$HTTP_HOST.$PHP_SELF."?".$QUERY_STRING."&istran=1";
else $url="http://".$HTTP_HOST.$PHP_SELF."?istran =1";

while (list ($key, $val) = every ($HTTP_COOKIE_VARS)) {
//echo "$key => $val
";
$ url.="&".$key."=".urlencode($val);
}

$fcontents = join( '', file( "$url" ) );
$code=new CCharset;
$fcontents=$code->Big5_Gb($fcontents);
//echo "轉換過的$CHAR_GB";
回顯$f內容；
退出；

}
//} else setcookie("CHAR_GB",0,time() 31536000);
echo "
