PHP - a DB abstraction layer use static class vs singleton object?

Question

I don\'t want to create a discussion about singleton better than static or better than global, etc. I read dozens of questions about similar subjects on SO, but I couldn\'t

Answer 1

My advice: STOP using Singleton and static all together.

Why? Because you will insert dependencies that will render your code unusable in other projects, and will not allow to unit test it. Also forget about loose coupling if using singleton.

The alternatives? Dependency Injection. http://www.potstuck.com/2009/01/08/php-dependency-injection
