该死的编码，输出怎么就不一样呢。

Question

$str = '&#21326&#21335'; 改成$str = '华南';也没用。

Answer 1

function utf8_replaceEntity($result){ 
    $value = (int)$result[1]; 
    $string = ''; 
    $len = round(pow($value,1/8)); 
    for($i=$len;$i>0;$i--){ 
        $part = ($value & (255>>2))  ¦ pow(2,7); 
        if ( $i == 1 ) $part  ¦= 255 <<(8-$len); 
        $string = chr($part) . $string; 
        $value >>= 6; 
    } 
    return $string; 
} function utf8_html_entity_decode($string){ 
    return preg_replace_callback( 
    '/&#([0-9]+);?/u', 
    'utf8_replaceEntity', 
    $string 
    ); 
} 
$string = '&#21326;&#21335;'; 
$str = '&#21326&#21335'; 
$string = utf8_html_entity_decode($string); 
echo iconv("UTF-8", "GB2312", $string); 
$str = utf8_html_entity_decode($str); 
echo iconv("UTF-8", "GB2312", $str); 怎么不小心点

Answer 2

你的编辑器里， &#  这些符号是什么编码的，我这里想保存，需要转换编码。

Answer 3

我读进来的文件，有5位的，也有2位的，&#21326 | &#65 ，2位的就要出错，
 Array
        (
            [0] => &#21326&#21335
            [1] => &#83&#76&#48&#49&#48&#56&#56
            [2] => &#24191&#24030&#19990&#35029&#27773&#36710&#36152&#26131&#26377&#38480&#20844&#21496
            [3] => &#65&#67&#84&#89&#79&#78
            [4] => &#65&#50&#48&#48&#88&#68&#105&#91&#50&#48&#48&#54&#93
            [5] => &#29233&#33150&#65&#50&#48&#48&#88&#68&#105
            [6] => &#71&#82&#69&#89
            [7] => &#28784&#33394
            [8] => &#76&#65&#75
            [9] => &#32463&#20856&#40657
            [10] => &#65&#72
            [11] => &#75&#80&#84&#67&#48&#66&#49&#75&#57&#55&#80&#48&#51&#57&#51&#57&#55
            [12] => &#50&#53&#53&#48&#48&#48
            [13] => &#21608&#23143&#33437
            [14] => &#50&#48&#48&#56&#45&#48&#51&#45&#48&#49
        )

终于解决了，麻烦，一个网上找的函数。function u2utf82gb($c){
    $str="";
    if ($c < 0x80) {
         $str.=chr($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);
}
