PHP MySQLi - MySQL Improved connection

Since MySQL extension is deprecated and will be removed as of PHP 5.5 onwards, I'll be teaching you how to connect to a mysql database using the new method, MySQL Improved or MySQLi. I'll be writing 2 methods on how to connect and query on MySQLi.

1) Simple connection

//First I'll  define variables
define("HOST","YOUR_MYSQL_HOST");
define("USER","YOUR_MYSQL_USERNAME");
define("PASS","YOUR_MYSQL_PASSWORD");
define("DBASE","YOUR_MYSQL_DATABASE");
