形如& # 20013 & # 22269的编码如何用PHP转换为汉字？

Question

echo urldecode("&#20013&#22269");

Answer 1

$str = urldecode("&#20013&#22269");
$str = mb_convert_encoding($str, "gb2312", "utf-8");
echo $str;

Answer 2

fdclf 没用，你看输出的源代码，还是&#20013&#22269
浏览器是能将&#20013&#22269转换为中国的

Answer 3

<?$str = "&#20013&#22269";echo preg_replace('/(\&\#)(\d{5})/mise',"iconv('UCS-2','GBK',pack('H4',dechex(\\2)) )",$str);?>

Answer 4

$str   =   "&#20013&#22269 "; 
$convstr=str2gb($str);
function str2gb($str){
$s=preg_replace("|&#([0-9]{1,5});|", "\".u2utf82gb(\\1).\"", $str);
$s="\$s=\"$s\";";
eval($s);
return $s;
}
function u2utf82gb($c){
    $str="";
    if ($c < 0x80) {
         $str.=$c;
    } else if ($c < 0x800) {
         $str.=chr(0xC0 | $c>>6);
         $str.=chr(0x80|$c & 0x3F);
    } else if ($c < 0x10000) {
         $str.=chr(0xE0|$c>>12);
         $str.=chr(0x80|$c>>6 & 0x3F);
         $str.=chr(0x80|$c & 0x3F);
    } else if ($c < 0x200000) {
         $str.=chr(0xF0|$c>>18);
         $str.=chr(0x80|$c>>12 & 0x3F);
         $str.=chr(0x80|$c>>6 & 0x3F);
         $str.=chr(0x80|$c & 0x3F);
    }
    return iconv('UTF-8', 'GB2312', $str);
}
