PHPStan 0.9 was in development for 3.5 months, and the number of new features reflects that — there’s really a lot in it. I liked the way GitHub writes up the changes in Git releases in a more human form, so I tried to do the same. Find out everything that’s new in PHPStan!

This week a new version of PHPStan comes out, one that will understand your code far better yet again. Among other things, it introduces so-called intersection types. Since this is a topic that stands on its own (you don’t always need to tie it to static analysis) and everyone writing modern web applications these days should care about type theory, I’ve put together a comparison of union types and intersection types.

At the beginning of December 2016 I released PHPStan, and it’s been enjoying great popularity ever since. It currently has over 1,300 stars on GitHub and over 30,000 downloads on Packagist. It makes me really happy and I love working on it.

On the PHPStan blog I wrote at length about how to go about it if you too want to create a useful, high-quality and successful open-source project. Spoiler alert: it’s not just about the code!

Last September I got in my car and set off on the 600-kilometer drive from Prague northeast toward Warsaw. In the remote complex of the gigantic Ossa hotel, the no less gigantic conference PHPCon Poland 2016 was being held, with a packed program full of talks by local and foreign speakers. And I was one of them.

I had prepared a talk about RabbitMQ. This topic is very close to my heart, because in PHP I like doing unconventional things detached from the classic „start up, handle the request and die“ model. By using RabbitMQ or another message queue you can make your application more efficient and, for instance, arrange for your users to receive a requested e-mail immediately, rather than only at the next run of a script via Cron.
