  • PHP 的 UNICODE 编码和解码


    方法一:
    <?php function unicode_encode($name) { $name = iconv('UTF-8', 'UCS-2', $name); $len = strlen($name); $str = ''; for ($i = 0; $i < $len - 1; $i = $i + 2) { $c = $name[$i]; $c2 = $name[$i + 1]; if (ord($c) > 0) { //两个字节的文字 $str .= '\u'.base_convert(ord($c), 10, 16).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT); } else { $str .= $c2; } } return $str; } //将UNICODE编码后的内容进行解码 function unicode_decode($name) { //转换编码,将Unicode编码转换成可以浏览的utf-8编码 $pattern = '/([\w]+)|(\\\u([\w]{4}))/i'; preg_match_all($pattern, $name, $matches); if (!empty($matches)) { $name = ''; for ($j = 0; $j < count($matches[0]); $j++) { $str = $matches[0][$j]; if (strpos($str, '\\u') === 0) { $code = base_convert(substr($str, 2, 2), 16, 10); $code2 = base_convert(substr($str, 4), 16, 10); $c = chr($code).chr($code2); $c = iconv('UCS-2', 'UTF-8', $c); $name .= $c; } else { $name .= $str; } } } return $name; }

    方法二:

      function unicode2utf8($str){
        if(!$str) return $str;
        $decode = json_decode($str);
        if($decode) return $decode;
        $str = '["' . $str . '"]';
        $decode = json_decode($str);
        if(count($decode) == 1){
          return $decode[0];
        }
          return $str;
        }
