In this post, I would like to introduce you to the set of best practices we have adopted at Moxio over the years.

On type safety without generics, and the role of package design

02-06-2017

Arnout Boks

At Moxio we strongly value writing type-safe code. This can be a challenge in PHP however, especially as it lacks a feature known as ‘generics’.
