PHP读取mssql,json数据中文乱码，_PHP教程

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：

<?<span>php    
    </span><span>header</span>("Content-Type: text/html;charset=utf-8"<span>);
    </span><span>//</span><span>告诉浏览器不要缓存数据</span>
    <span>header</span>("Cache-Control: no-cache"<span>);    
    
    </span><span>require</span> "../conn.php"<span>;
    </span><span>require</span> "../share/json_gbk2utf8.php"<span>;

    </span><span>$query</span> = '<span>SELECT 
                seq,
                employeeID,
                employeeName,
                department,
                position,
                sex,
                birthday,
                entryTime,
                description,
                convert(varchar(20),createTime,120) as createTime,<span>;    
    </span><span>$arr</span> = <span>Array</span><span>();
    </span><span>$query</span> = <span>iconv</span>("utf-8", "gbk//ignore", <span>$query</span>);<span>//</span><span>为了解决中文乱码问题    </span>
    <span>if</span>(<span>$result</span> = sqlsrv_query(<span>$conn</span>, <span>$query</span><span>)){
        </span><span>while</span>(<span>$row</span> = sqlsrv_fetch_array(<span>$result</span><span>)){
            </span><span>$arr</span>[] = <span>$row</span><span>;            
        }
    }
    </span><span>$data</span> = JSON(<span>$arr</span><span>);
</span><span>//</span><span>     file_put_contents("E:/mylog.log", "JSON:".$data."\r\n", FILE_APPEND);    </span>
    <span>echo</span> <span>$data</span><span>;
</span>?>

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>php 
    </span><span>/*</span><span>*
     * 如果员工编号在MySql中不存在则在MySql中插入员工记录
     * 如果该员工编号已经存在则进行更新操作
