php的汉字转换:GBK至Big5_PHP

P>php的汉字转换一直是比较麻烦的事

首先要说两点:
1.GBK的繁体字并不是Big5,但一般繁体字都有对应的Big码
2.一GBK码并不一定有对应的Big5码,所以一般是不可逆转换

该类内置了三个函数
qswhStr 格式化字符串
qswhFile 格式化一文件
qswhDir 格式化目录下所有文件(.qswh的除外,那是原先文档的备份)

qswhBig5.php 从这里下载
http://www.blueidea.com/user/qswh/qswhBig5.zip

class qswhBig5{
var $qswhData;
function qswhBig5($filename="qswhBig5.php"){
$this->qswhData=file($filename);
}
function qswhStr($gb,$fail="??"){
/******(qiushuiwuhen 2002-9-6)******/
$ret="";
for($i=0;$i if(($p=ord(substr($gb,$i,1)))>127){
$q=ord(substr($gb,++$i,1));
$tmp=$this->qswhData[$p-128];
for($j=0;$j=$q)break;
if($k==$q)$q=chr(hexdec(substr($tmp,$j+2,2))).chr(hexdec(substr($tmp,$j+4,2)));
else if($fail=="")$q=chr($p).chr($q); else $q=$fail;
}
else
$q=chr($p);
$ret.=$q;
}
return $ret;
}
function qswhFile($filename,$fail="??"){
/******(qiushuiwuhen 2002-9-6)******/
if(!file_exists($filename.".qswh"))copy($filename,$filename.".qswh");
$fp=fopen($filename,"r+");
$tmp=fread($fp,filesize($filename));
rewind($fp);
fwrite($fp,$this->qswhStr($tmp,$fail));
fclose($fp);
}

function qswhDir($dirname,$fail="??"){
/******(qiushuiwuhen 2002-9-6)******/
$d = dir($dirname);
while($entry=$d->read()) {
if($entry=="."||$entry=="..")continue;
$entry=$dirname."/".$entry;
if(is_dir($entry))
$this->qswhDir($entry,$fail);
else{
if(substr($entry,-5)!=".qswh")$this->qswhFile($entry,$fail);
}
}
$d->close();
return $c;
}

}


使用范例:
$words="秋水无恨";
$qswh=new qswhBig5("qswhBig5.php");//qswhBig5.php,可省参数

echo("

请选择编码Big5查看:".$qswh->qswhStr($words));<br />echo("\n编码一目录:".$qswh->qswhDir("test"));<br />echo("\n编码一文件:".$qswh->qswhFile("index.htm"));</p> <p><br />使用说明:<br />qswhStr中第二个参数代表如果没有对应的Big5将替换的字,如果为空,则保留该字<br />将文件格式化后,记得要修改<meta中的content-type为Big。 </div> <div class=""> <ul class="m-news-opt fix"> <li class="opt-item"> <a href='/PHPjiqiao-92591.html' target='_blank'><p>< 上一篇</p><p class="ellipsis">smarty实例教程---程序设计部分_PHP</p></a> </li> <li class="opt-item ta-r"> <a href='/PHPjiqiao-92593.html' target='_blank'><p>下一篇 ></p><p class="ellipsis">Compilingphpwithcrypt()_PHP</p></a> </li> </ul> </div> </div> </div> <div class="g-title fix"> <h2 class="title-txt">人气教程排行</h2> </div> <div class="m-rank u-dashed mb40"> <ul> <li class="rank-item"> <a href="/PHPjiqiao-379253.html" title='php如何获取跳转前的url' class="item-name ellipsis" target="_blank"> <span class="g-art-count fr">174次</span> <span class="g-sort-num top">1</span> php如何获取跳转前的url </a> </li> <li class="rank-item"> <a href="/PHPjiqiao-379019.html" title='php格林威治时间转换成当前时间的方法' class="item-name ellipsis" target="_blank"> <span class="g-art-count fr">174次</span> <span class="g-sort-num second">2</span> php格林威治时间转换成当前时间的方法 </a> </li> <li class="rank-item"> <a href="/PHPjiqiao-366629.html" title='为什么php不能做大型系统?' class="item-name ellipsis" target="_blank"> <span class="g-art-count fr">174次</span> <span class="g-sort-num third">3</span> 为什么php不能做大型系统?
