PHP reads mssql2008, json data is garbled in Chinese_PHP tutorial

PHP and web pages use UTF-8 encoding, the database is sql server2008, and the default encoding (936, GBK encoding) is used
When reading database data, use the json_encode() that comes with PHP to return to the front end, and the results will not be displayed in Chinese.

Solution:

employeeGet.php 
<?php     
    header("Content-Type: text/html;charset=utf-8"); 
    //告诉浏览器不要缓存数据  
    header("Cache-Control: no-cache");   
     
    require "../conn.php"; 
    require "../share/json_gbk2utf8.php"; 
 
    $query = &#39;SELECT  
                seq, 
                employeeID, 
                employeeName, 
                department, 
                position, 
                sex, 
                birthday, 
                entryTime, 
                description, 
                convert(varchar(20),createTime,120) as createTime,<SPAN style="COLOR: #ff0000">//这里要注意，因为mssql2008的datetimne类型是带有毫秒的，直接在前端显示  
可能会有问题，所以要做一次转换</SPAN> 
                convert(varchar(20),updateTime,120) as updateTime                            
            FROM employees&#39;;     
    $arr = Array(); 
    $query = iconv("utf-8", "gbk//ignore", $query);//为了解决中文乱码问题  
    if($result = sqlsrv_query($conn, $query)){ 
        while($row = sqlsrv_fetch_array($result)){ 
            $arr[] = $row;           
        } 
    } 
    $data = JSON($arr); 
//  file_put_contents("E:/mylog.log", "JSON:".$data."\r\n", FILE_APPEND);     
    echo $data; 
?>

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 ：

<?php  
    /**
     * 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

    header("Content-Type: text/html;charset=utf-8");
