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

  - by Pheter

  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.)

Also, I have turned off magic_quotes.

  Traits have been one of the biggest additions for PHP 5.4. I know the synatax and understand the idea behind traits, like horizontal code re-usage for common stuff like logging, security, caching etc. However, I still dont know yet how I would make use of traits in my projects. Are there any open source projects that already use traits? Any good articles/reading material on how to structure architectures using traits?

My code is as follows: if (!$this->connection[0]->query($this->query)) throw new Exception($this->connection[0]->error); What are the pros and cons of using exceptions for this kind of cases (failed queries)?
