PHP mysqli_set_charset()Functions

PHP MySQLi 参考手册PHP MySQLi Reference Manual

Set the default client character set:

<?php 
// 假定数据库用户名：root，密码：123456，数据库：EXAMPLE 
$con=mysqli_connect("localhost","root","123456","EXAMPLE"); 
if (mysqli_connect_errno($con)) 
{ 
    echo "连接 MySQL 失败: " . mysqli_connect_error(); 
} 

// 修改数据库连接字符集为 utf8
mysqli_set_charset($con,"utf8");

mysqli_close($con);
?>

This operation is very useful for Chinese characters; many cases of garbled database queries are due to character set issues.
