Dependency Injection or using Pimple as container

We'll discuss the three main styles of dependency injection, Inversion of Control (IoC), service locators, and factory services.

We'll talk about why using new or calling static methods inside classes is bad.

I'll demo the use of Pimple as an IoC container and how it, combined with dependency injection, leads to more testable, more maintainable, more reusable objects.
