Answer 1

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。

Answer 2

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);

Answer 3

PHP输出数组：

Answer 7

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。
