PHP解码unicode编码的中文字符代码分享,

问题背景:
晚上在抓取某网站数据,结果在数据包中发现了这么一串编码的数据:"......\u65b0\u6d6a\u5fae\u535a......", 这其实是中文被unicode编码后了的数据,我现在就是想解码出中文来,上度娘搞了半天,试了很多的姿(方)势(法),终于搞定了。

解决方案:
呵呵,老外就是给力啊, 猛戳这里看老外给的解决方案

方案A(稳定版+推荐):

function replace_unicode_escape_sequence($match) {
  return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');
}
$name = '\u65b0\u6d6a\u5fae\u535a';
$str = preg_replace_callback('/\\\\u([0-9a-f]{4})/i', 'replace_unicode_escape_sequence', $name);
echo $str; //输出: 新浪微博 
Copy after login
//咱将上述方案A给封装起来~~~(方案A稳定版+升级+推荐)
class Helper_Tool
{
  static function unicodeDecode($data)
  {  
    function replace_unicode_escape_sequence($match) {
      return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');
    }  
 
    $rs = preg_replace_callback('/\\\\u([0-9a-f]{4})/i', 'replace_unicode_escape_sequence', $data);
 
    return $rs;
  }  
}
//调用
$name = '\u65b0\u6d6a\u5fae\u535a';
$data = Helper_Tool::unicodeDecode($name); //输出新浪微博
Copy after login


方案B(次推荐):

<&#63;php
function unicodeDecode($name){
  $json = '{"str":"'.$name.'"}';
  $arr = json_decode($json,true);
  if(empty($arr)) return ''; 
  return $arr['str'];
}
$name = '\u65b0\u6d6a\u5fae\u535a';
echo unicodeDecode($name); //输出: 新浪微博 
Copy after login

对于方案B, 我要特别重点说明下注意事项, 在好友 XAR (猛戳XAR博客) 的技术支持下,总结出要处理的字符串(即传递给函数unicodeDecode的参数$name的内容中一定不能包含单引号,否则就会导致解析失败, 所以有必要的话可以借助 str_replace()函数将非法字符格式化为合格字符)
