Sam Hennessy has posted the first part (part 0, actually) of a manifesto he's been working oup about dependency injection in PHP applications.
This article is part of a series where I will go into great detail about Dependency Injection (DI) and how it applies to PHP. I will layout exactly how I think DI should be used in PHP with the creation of a new code project as the result.
The series is his outlet to share some of his thoughts and feelings and some of the experience he's gathered during his time working on a dependency injection framework of his own.
This series I will be putting forward my honest opinion. The thinking will be based around the use of DI in PHP shops with many projects of differing sizes. As such my opinion will not be what everyone needs. This will not be a tutorial but I will provide links so that people new to the concepts can look them up.
