如何在尚未创建数据库时初始化mysqli变量[关闭]

Question

I am using mysqli inorder to use database functionality in PHP. So, when I use new mysqli(.,.,.,.,db_name), I need to mention db_name in the begining. I want to create a db after opening a connection. So, obviously I wont be able to give db_name value while initializing. So, how to initialize a mysqli variable using which I can create a database $mysqli->query("create database Sample"), for example.

$mysqli = new mysqli("localhost","root","1sdfd6","Sample","3306");
//How can i provide Sample here when i am creating sample in next statement

$mysqli->query("create database Sample");                               
$mysqli->select_db("Sample");

Read this: http://www.php.net/manual/en/mysqli.construct.php.

The database parameter (just like all the other parameters the mysqli constructor) is optional.

Though perhaps you should reconsider your plan of attack?
