Contract Tests
There is more to the contract of an interface than just the methods it provides. All implementation of this interface actually need to behave consistently in the same situations. This post shows a way how we can test for this.

Back the func off, this is my abstraction!
Integrating services over API's exposes your application to a range of possible failures. At scale, any network interaction can and will fail. Implementing a retry mechanism is a common approach to increase fault tolerance. Taking into account how systems fail when designing software can greatly improve the quality of your code. In this blogpost I'd like to show how I approach these kinds of problems.

Object Oriented Done Right
Alan Kay, the inventor of the term “object-oriented programming”, told a story once during a talk more than 20 years ago. You can build a dog house using only a hammer, nails, planks, and just a little bit of skill. I figure even I would be able to build it given enough time. Once you've built it you've earned the skills and know-how, and could apply it to other projects. Next, you want to build a cathedral, using the same approach with your hammer, nails, and planks. It's a 100 times larger, but you've done this before — right? It'll only take a little longer.

Roadmap to learn Software Design
I have been planning to learn Software Design for a quite a while now but I always ended up finding some other fancy topic. You can be a software engineer with years of experience and still do fine without delving into the meat of Software design but the perks of understanding this complex process are unfathomable.

Fiendish Functions - Filtering Fact From Fiction
Functional programming is a paradigm that has gained in popularity recently with the rise of several new functional programming languages and integration of new features in existing languages. All the same, there are many concerns about functional programming in the developer community. Is functional programming useful for the PHP developer? Will it add complexity to my codebase? This article will respond to some of these misconceptions.

13 Best Practices for Building RESTful APIs
Facebook, GitHub, Google, and many other giants need a way to serve and consume data. A RESTful API is still one of the best choices in today’s dev landscape to serve and consume data.
But have you ever considered learning about industry standards? What are the best practices for designing a RESTful API? In theory, anyone can quickly spin up a data API in less than five minutes — whether it be Node.js, Golang, or Python.

How to connect with gRPC service in PHP application? gRPC PHP tutorial
More and more developers and companies are discovering the benefits of microservices. And while PHP is usually not the first choice for this architecture, it is now more than viable to create efficient web apps based on microservices with PHP. To that end, Google’s gRPC and Protobuf solutions are a big help. Today, I’m going to show you how to use gRPC with PHP.

The Domain Layer - Clean Architecture & Domain-Driven Design on PHP
The fundamental part of Clean Architecture and Domain-Driven Design is the Domain layer. There all the business and applications rules are laid down and will be controlling the processing of information independently from the infrastructure and frameworks.

Double Dispatch
The computation of a method call is only dependent on the object receiving the method call. Most of the time that's enough. However, sometimes we need the computation to also depend on the argument being passed to the method call.
Think you have two hierarchies of objects interacting with each other and the computation of these interactions depends on both objects, not only in one of them. Maybe some examples will make this clearer.

What is Software Architecture?
When it comes to the definition of Software architecture is the process of transforming software features such as flexibility, scale, viability, reusability, and security into a structured solution that meets technological and business aspirations. This definition refers to the features of the software that can affect software architecture. In addition to technical requirements, a long list of features primarily represents a business or operational needs.

Writing better Regular Expressions in PHP
Regular Expressions are powerful, PHP but they are not known to be readable, and more often than not, maintaining a regular expression is not a straight-forward task.

PHP 8.1 is coming — and it already promises to be one of the best releases
The coming version of PHP, scheduled for November 2021, is already packed with a lot of super exciting features.

Design Patterns — The Observer Pattern
This is part 2 of my design patterns articles. A lot of credit to Christopher Okhravi. I’m trying to cover all his videos about design patterns from the book "Head First: Design Patterns".

Why our code tends to become big ball of mud over time
Our codebases seem to corrode over time. Overall quality tends to decrease. Each new change is harder to introduce. We all use OOP good practices, control our dependencies, adjust to SOLID principles and use patterns. And even so, our systems head toward becoming a big ball of mud inevitably. It turns out it is not enough to keep systems viable in an environment of relentless change.

Best practices for writing code comments
While there are many resources to help programmers write better code—such as books and static analyzers—there are few for writing better comments. While it's easy to measure the quantity of comments in a program, it's hard to measure the quality, and the two are not necessarily correlated. A bad comment is worse than no comment at all. Here are some rules to help you achieve a happy medium.

Enums in PHP 8.1
They are finally coming — built-in support for enums will be added in PHP 8.1! Some might consider them long overdue, but you don't hear me complain; I'm glad they made it! This post is dedicated to looking at the newly added feature in-depth.

PHP 8: The JIT
The pros and cons of adding a JIT compiler to PHP. Dmitry Stogov recently opened an RFC to add a JIT compiler to PHP. So, what is that about? Does "JIT" mean "instantly better PHP", or is this a more nuanced topic? Today we'll briefly look at what the "JIT" actually does, and more importantly: the difficulties and opportunities it brings to the PHP world.

PHP: Named arguments are your friends
I stumbled upon an article in Stitcher.io that, in a few words, declares that developers should be aware that Named Arguments will break things. That’s quite weird when you consider they fix more than what they "break".

Modern PHP data Encryption/Decryption with Sodium extension
Throughout the years PHP has added support for several extensions, libraries, and algorithms to encrypt and decrypt data. With several libraries and extensions with various levels of maintenance, several algorithms each potentially carrying pros and cons, some even inherently being insecure, it is very difficult to select the appropriate PHP extension, library, encryption constructs, and balance the security and performance.
