Can I use an abstract class instead of a private __construct() when creating a singleton in PHP?

When creating a Singleton in PHP, I ensure that it cannot be instantiated by doing the following:
class Singleton {
private function __construct() {}
private function __clone() {}
public static function getInstance() {}
}
However, I realised that defining a class as 'abstract' means that it cannot be instantiated. So is there anything wrong with doing the following instead:
abstract class Singleton {
public static function getInstance() {}
}
The second scenario allows me to write fewer lines of code which would be nice. (Not that it actually makes much of a difference.)
