    $con = mysql_connect("localhost","root","1234");  
    mysql_select_db("test",$con);  

mysql_query("set names utf8"); 
mysql_query("set character_set_client=utf8"); 
    mysql_query("set character_set_results=utf8");


    $q=mysql_query("SELECT * FROM people");  
    while($e=mysql_fetch_assoc($q)){
        $output[]=$e;  }
        print(json_encode($output));  
        mysql_close();  
?>  



输出结果:
[{"id":"10","name":"John","sex":"1","birthyear":"1979"},{"id":"11","name:"\u5f20\u4e09","sex":"1","birthyear":"1989"}]

为什么不是 张三
------解决方案--------------------
因為你json_encode了,中文會轉未union編碼

print(json_encode($output)); 
改成
print($output); 

如果你json_encode后也想看到中文,可以參考我之前寫的文章:http://blog.csdn.net/fdipzone/article/details/28766357
------解决方案--------------------
json_encode 只接受 utf-8 编码的数据
json_encode 在做 json 编码时,会将多字节的 utf-8 字符转换成双字节的 unicode 编码的实体形式
这样在任何环境中bouquet不会因编码的原因造成数据的失真
json 数据格式主要用于与 js 通讯,而浏览器会将任何编码的数据转换成其工作字符集 unicode
所以,json_encode 的转码工作有利于减轻浏览器的压力
