Since PHP 8.1, we can use Enums in our PHP projects. But how many developers are actually taking advantage of them? Many are still unaware of the benefits of enums, and even those who are using them are not fully exploiting their potential. In my presentation, I will refactor an entire project using Enums to explain their advantages and possible applications. This will illustrate how enums can elevate the developer experience and enhance the overall quality of our projects.
