Object Oriented mysqli connection function

[PsychoCoder]

Recently a friend was having a hard time connecting using mysqli, so I showed an OO way of accomplishing the task with this code

class db_connection extends mysqli 
{
    public function __construct($dbhost, $username, $password, $db) 
    {
        parent::__construct($dbhost, $username, $password, $db);
 
        if (mysqli_connect_error()) 
        {
            die('Connection Error: (' . mysqli_connect_errno() . ') ' . mysqli_connect_error());
        }
    }
}
 
$db = new db_connection('localhost', 'username', 'password', 'db');
 
echo 'Success... ' . $db->mysqli_get_host_info($db) . "\n";
 
$db->close();

if it is not required to use MySQLi, I recommend to use PDO. if that has a connection problem, a PDOException is thrown automatically (and you can set PDO to use Exceptions for every error it encounters).
