PHP解码unicode编码中文字符代码

 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
 // www.jbxue.com 脚本学堂
 //咱将上述方案A给封装起来~~~(方案A稳定版+升级+推荐)

 return $rs;
 }
 }
 //调用
 $name = '\u65b0\u6d6a\u5fae\u535a';
