That depends. If you only need only one connection to the database (you usually don't need more than one), then a singleton could be implemented:
PHP Code:
class XYZ
{
protected static $instance = null;
public static function getInstance()
{
if(self::$instance instanceof self === false) self::$instance = new self();
return self::$instance;
}
private function __construct() { }
private function __clone() { }
}
That way, you can't clone or create multiple instances of the same object. But again, that depends, there are cases when you need a clone of the db object (e.g.: nested fetching), and in that case it's better if you leave out the implementation of the magic clone method.
