php mysqli 查询乱码问题

mysqli因为默认是latin-1编码，当你的页面时utf-8编码是，就会产生页面乱码问题。

mysqli乱码解决办法：

$mysqli = new mysqli("localhost","root","password","dbname");//mysqli链接数据库的写法

//$mysqli->query("SET NAMES utf8");//写法一

$mysqli_query($db,"SET NAMES utf8");//写法二

1)mysql乱码解决办法同上（原理相同）：

$db =mysql_connect("localhost","root"," password ") or die("unable to connect"); 

//$db->query("SET NAMES utf8");//写法一

mysql_query($db,"SET NAMES utf8");//写法二
