There is nothing wrong with this line

Here php looks for class named DATABASE_CLASS because
of the new keyword and not for the contain of DATABASE_CLASS.

That's why you get this error.

Yes:

define(DATABASE_CLASS, MySQL_5_Database);
..
..
..
$class_name = DATABASE_CLASS;

$db = new $class_name ($user, $pwd, $dbName);

Now, PHP knows that $class_name is a variable that contains the name of the
class.
That why it should work.
