Build a PHP Framework: Interfaces
In this video you'll learn how straightforward it is to swap one class for another when they implement the same interface in PHP. This is something that PHP frameworks like Laravel and Symfony make use of extensively.
This is the sixth in a series of videos that will teach you how frameworks work in PHP by building one step by step. In this project-based tutorial, I'll be doing this using modern standards, best practices and third party packages where necessary.
In order to follow along you need to already be familiar with basic PHP.
