PHP读取mssql,json数据中文乱码，

PHP读取mssql,json数据中文乱码，

PHP及网页使用UTF-8编码，数据库是sql server2008,使用默认编码（936，即GBK编码）

当读取数据库数据时，使用php自带的json_encode()返回到前端，结果中文不显示。

解决办法：

这样，sql server 2008中的中文就可以在网页正常显示了。

如果要将中文正常插入到sql server 2008中，还要加入一条代码：$query = iconv("utf-8", "gbk//ignore", $query);//为了解决中文乱码问题

完整代码如下 ：

    </span><span>/*</span><span>*

     * 如果该员工编号已经存在则进行更新操作
