php json_encode加密后，有的汉字显示不出来 急

[bluezsh]

$e=mb_detect_encoding($str) 输出个字符编码类型，怎么会这样？
ASCII-------------
UTF-8-------------,王五
UTF-8-------------,赵六
ASCII-------------2014-07-16
-------------电子商务品牌市场部
-------------工作简报
UTF-8-------------未存档
UTF-8-------------未发送
-------------经理办公室
ASCII-------------2
UTF-8-------------以后的文号只须选择文号头后系统将自动生成
UTF-8-------------我 是 谁
ASCII-------------11
ASCII-------------2014
ASCII-------------
-------------测试部门
ASCII-------------
UTF-8-------------李刚,郭美美,赵智勇,张田欣
ASCII-------------Admin
-------------工作简报的总第期数和当年期数都可以由系统自动生成，生成后在发文表列表中可以查看
UTF-8-------------研发中心
-------------集团领导

使用 json_encode 对数组加密后，输出的汉字部分是空的，怎么回事了？
各位大侠们，有没有好的解决方案？ 急救

[bluezsh]

有的编码是空，有的编码是 ASCII，UTF-8，CP936也有，不知道为什么会这样。

你原始的数据是怎样的？ 可以的话贴出序列化后的结果 echo serialize($data);

你原始的数据是 gbk 的，这是不能被 json_encode 所接受的 json_encode 只接受 utf-8 编码的数据，于是 gbk 汉字因不能识别而丢弃 只有少量的字符组合被错误的解释为 utf-8 双字节字符而被保留了下来，造成了你的疑惑不解，要是一个都不剩的话，反倒使事情明朗化了 所以如果你需要产生 json 的话需要做一下编码转换

array_walk_recursive($ar, function(&$s) { $s = iconv('gbk', 'utf-8', $s); });

如果数据是从 mysql 读取的，那么只需在读取前执行一次

mysql_query('set names utf8');

就完事大吉了

非常感谢，我试试，我的是mssql数据库中读取过来的。
