怎样才能转换为正常的中文？

Question

$str = "张三";//这两个的结果都一样:张三
print_r( iconv('', 'UTF-8', $str) );
print_r( unescape($str) );function unescape($str) {
    $str = rawurldecode($str);
    preg_match_all("/(?:%u.{4})|&#x.{4};|&#\d+;|.+/U",$str,$r);
    $ar = $r[0];
    //print_r($ar);
    foreach($ar as $k=>$v) {
        if(substr($v,0,2) == "%u"):
            $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,-4)));
        elseif(substr($v,0,3) == "&#x"):
            $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));
        elseif(substr($v,0,2) == "&#"):
            //echo substr($v,2,-1)."\r\n";
            $ar[$k] = iconv("UCS-2","UTF-8",pack("n",substr($v,2,-1)));
        endif;
    }
    return join("",$ar);
}

Answer 1

我读出来是%u9996%u9875...之类的不是$str = "张三";

Answer 2

javascript:alert(unescape('%u9996%u9875'));
此代码浏览器地址栏运行即可...那个是escape转换过的代码.
所以用unescape转回来就可以了.

Answer 3

晕..PHP版...那个...9996是unicode编码...
首先把它转换成10进制,然后在对照unicode表转成值就可以了.
过程是这样滴.javascript:alert(String.fromCharCode(parseInt(9996, 16)));

Answer 4

9996是16进制的unicode编码... 

Answer 5

php中转换的！！我用iconv转怎么不行啊

Answer 6

<?php
$s = "%u9996%u9875";
echo(unescape($s));function unescape($str) {
         $str = rawurldecode($str);
         preg_match_all("/%u.{4}|&#x.{4};|&#\d+;|.+/U",$str,$r);
         $ar = $r[0];
         foreach($ar as $k=>$v) {
                  if(substr($v,0,2) == "%u")
                           $ar[$k] = iconv("UCS-2","GBK",pack("H4",substr($v,-4)));
                  elseif(substr($v,0,3) == "&#x")
                           $ar[$k] = iconv("UCS-2","GBK",pack("H4",substr($v,3,-1)));
                  elseif(substr($v,0,2) == "&#") {
                           $ar[$k] = iconv("UCS-2","GBK",pack("n",substr($v,2,-1)));
                  }
         }
         return join("",$ar);
} 
?>

Answer 7

$str = "&#24352&#24352;&#19977;%u9996%u9875";print_r( unescape($str) );function unescape($str) {
    $str = rawurldecode($str);
    preg_match_all("/(?:%u.{4})|&#x.{4};?|&#\d+;|.+/U",$str,$r);
    $ar = $r[0];
    print_r($ar);
    foreach($ar as $k=>$v) {
        if(substr($v,0,2) == "%u"):
            $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,-4)));
        elseif(substr($v,0,3) == "&#x"):
            $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));
        elseif(substr($v,0,2) == "&#"):
            echo substr($v,2,-1)."\r\n";
            $ar[$k] = iconv("UCS-2","UTF-8",pack("n",substr($v,2,-1)));
        endif;
    }
    return join("",$ar);
}

Answer 8

这种方法不行，我用对照表的方式已经弄出来了，但是觉得太笨拙了，有没有直接就把unicode字符转为iso-8859-1的方法

Answer 9

+{unescape}+
输出编码：utf-8。
+ (加号) 解析为空格。
%?? 解析为单字节字符。
%u???? 解析为 unicode 字符。<?phpfunction unescape($s) {
return preg_replace_callback('/%u([\da-fA-F]{4})/', 'unesacpe_unicode_match', urldecode($s));
}function unesacpe_unicode_match($matches) {
return iconv('utf-16', 'utf-8', pack('H4', $matches[1]));
}echo unescape('this+is+%u9996%u9875.%20'); // prints "this is 主页. ". ?>
