In this publication of my PHP related blog series, I want to address Pure Intersection Types in PHP. In the previous blogs of the series, I addressed different features added to PHP with PHP 8 and PHP 8.1. The first blog was about readonly properties, the second one focused on Enums and the third and … read more …
PHP added Enums with version 8.1. Finally! Many other programming languages such as Java and C# have enums for a long long time.

The beginning of this week was a little bit more action packed than planned. After a couple of weeks of coding and intensive testing (seriously!), a colleague and me were of the opinion that the feature is production ready and could be deployed. But well, shit happens when you least expect it. We faced PHP … read more …
One of my partners asked me for support on his personal website. He is not a pro user, meaning that he created a simple website a couple of years ago and relies on support of his hoster. Stuff like responsive design and SEO (what is this?) does not matter and he just wants to publish … read more …

New team members, for instance, do not need to set up, but can simply run ‘vagrant up’ to have a fully configured, ready-to-start environment. Personally, in my case, it is … read more …
The new years first blog is about algorithms – more precisely: 2 dimensional matrices. I want to explore the ways how to find connected 1’s (so called islands) in a 2D array. This problem is also known as the “find the number of islands” or “connected components in an undirected graph“. In this post, we … read more …
