模仿OSO的论坛（二）从C/C++迁移到PHP：判断字符类型的函数

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
<? //=====================================================
// 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));
$x=ord(substr($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) {
$c=ord(substr($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 Big5_Gb($str) {
$fd = fopen ($this->gb_map, "r");
$str=str_replace("charset=big5","charset=gb2312", $str);
$outstr="";
for($i=0;$i<strlen($str);$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;$i<strlen($str);$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" ) );
$fcontents=str_replace("<head>","<head><base href=$file>", $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";
$t=time();
echo "
<script language=javascript>
document.location='$url'
</script>
";
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, $val) = each ($HTTP_COOKIE_VARS)) {

$url.="&".$key."=".urlencode($val);
}
$fcontents = join( '', file( "$url" ) );
$code=new CCharset;
$fcontents=$code->Big5_Gb($fcontents);
//echo "轉換過的 $CHAR_GB";
echo $fcontents;
exit;
}
//} else setcookie("CHAR_GB",0,time()+ 31536000);
