Layers, Ports & Adapters - Part 3, Ports & Adapters
In the previous article we discussed a sensible layer system, consisting of three layers: domain, application, infrastructure. A port is an abstract thing, it will not have any representation in the code base. For each of these abstract ports we need some code to make the connection really work. We need code for dealing with HTTP messages to allow users to talk to our application through the web.

Microservices for Lunch
You are a software developer, and your are on lunch break. Today, you decide not to go for lunch with the team, because you have some shopping to do. You have been invited by a special person for the next day, and you want to bring along a nice gift. You enter your favourite shop, and manage to find a nice little something that will be the perfect gift for your host. You line up at the cashier. Luckily, you are at the front of the line very soon.

Duolingo for PHP – How Much PHP Can Apps like Mimo Teach
Mimo is an app which claims to teach coding “on the go”. As a long time Duolingo user, I could relate to this approach – particularly as I was becoming increasingly interested in achieving some degree of basic Swift literacy in the coming weeks. In an attempt to objectively assess the app’s ability to teach people new things, I decided to look at what it’s offering and see if it’s something I can recommend to people just starting out with a new language.

SEO Guide for Blogs, Business and eCommerce Websites in 2017
Whether you’re running a blog, a business website or an online shop, in 2017 you can’t do without a solid SEO strategy. How do you bring more traffic to your website? 80% of web traffic is generated via search engines, so it’s about time you thought of investing into a solid SEO campaign.

The “Micro” Framework As “User Interface” Framework
“Micro” frameworks are better described as “user interface” frameworks; perhaps there should be corollary “infrastructure” frameworks; consider using two frameworks and/or two containers, one for the user interface and a separate one for the core application.

Tutorials and Talks

Pagination in CodeIgniter: The Complete Guide
The benefit of using any full-stack web application framework is that you don't have to worry about the common tasks, like input handling, form validation and the like, as the framework already provides wrappers for those features. Thus, it allows you to concentrate on the business logic of the application rather than reinventing the wheel over and over again. Today, we're going to explore an important library in the CodeIgniter framework - the pagination library.

Guru: The PHP Path To Victory, Part 2
Part 1 of this article discussed the path a PHP request takes on its way to your backend RPG program through the magic of an external SQL stored procedure. Part 2 will give you the confidence to troubleshoot those times when something unexpected occurs in this PHP environment.

Custom Disks For Your Laravel Users
In one of my side projects, a tool that I’m developing for myself, I let users retrieve files from a custom file-system. Laravel provides a nice integration of the Flysystem library from The PHP League. With Laravel, you need to configure your file-system from config/filesystems.php. Sure enough, this works if you want to configure the disks for your application. What if you want to provide the user the ability to access his files? It’s a matter of League\Flysystem\Filesystem and of an adapter.

Application Logic Done Right
How to organise a clean, testable and reusable application logic.

Precision Through Imprecision: Improving Time Objects
When creating value objects representing time, I recommend choosing how finegrained the time should be with your domain experts and round it off to that precision in the value object.

Single Sign On—You’re Probably Doing It Wrong
Requiring users to log in individually to all the websites they need for their work is more than merely annoying: It wastes a lot of time and turns maintaining log-in credentials and permissions into a nightmare for the administrative staff. Let’s see if we can fix that with a single sign-on service.

Closures, Anonymous Classes and an Alternative Approach to Test Mocking (Part 2)
The last time I posted here, I was writing about Anonymous Functions and how they can be bound to any object (or class) to execute as though they are a method within the scope of that class (Closure Binding as an alternative to “use” variables); and in the first article in this series, I looked at using a Closure to access private and protected properties of an object.

Behind-the-Scenes: How We’re Automating Acceptance Testing
Have you ever had the joy of carrying out acceptance tests? For our team at Delicious Brains, testing our releases, in the past, has been one of the most dreaded tasks on the to-do list. We hold our plugins to a high quality standard so it’s a must, but manual tests are brain-numbingly tedious and can take hours of expensive developer time. Recently, we decided it was high-time to fix that.

Magento 2 Performance on Docker (a preliminary test)
Magento 2 on Docker on Mac is a horrible experience and it is specifically because of file system performance. But on Linux I’ve had good experiences. However, those experiences were with Magento 1 and not Magento 2. Magento 2 relies on the file system more than Magento 1 so it is quite plausible that Magento 2 is slow as molasses on Docker. So I decided to do a quick load test on a Linux system I have here (have I mentioned that I offer a load testing service for Magento?) and see if the results are worth pursuing further.

Writing Clean Code
Three simple practices to help write clean code and improve the readability of a codebase.

New Date/Time Support in MongoDB
In the past few months I have been working on adding time zone support to MongoDBs Aggregation Framework. This support brings in the timelib library that is also used in PHP and HHVM to do time zone calculations.

PHPBot – Can a PHP Bot Help You Look up Documentation Faster?
I came across PHPBot the other day (not to be confused with Botman or Fondbot) – a “chatbot” which helps you look up PHP manual entries and generates example code for them. If you follow me on Twitter, you know I don’t believe in chatbots being chatbots – as someone who’s built some for both commercial purposes and personal ones, and as someone who was around in the age of IRC auto-responding scripts, I see chatbots as a little more than a marketing fad designed to impress todays Snapchat generation. However, every now and then one will appear that’s actually useful. Could this be the one? Let’s take a look.

Optimise Eloquent Queries with Eager Loading
Object Relational mapping (ORM) makes working with databases amazingly simple. While defining database relationships in an object-oriented way makes it easy to query related model data, developers might not pay attention to the underlying database calls. A standard database optimisation for an ORM is eager-loading related data. We will set up some example relationships and then walk through how queries change with and without eager loading.

How to Implement a Year 2038 Problem Fix in PHP Applications that Are Using Unix Timestamps
Many PHP applications use Unix timestamps to make calculations with the dates and times of events. However, using Unix timestamps for these purposes will lead to a very big problem well known as the bug of year 2038. Read this article to know more about the bug of year 2038 and how fix the issue with an alternative way to manipulate times and dates.

How to Pass Data From Controller to View in CodeIgniter
A view is webpage that displays all the elements of the UI. In many cases, view is often a fragment of page (such as header, footer, widget areas and sidebars). In many cases, views can be embedded in other views. One important aspect of views is that views could not be called directly. You need to load the views through a controller. In this tutorial, I will highlight the simple, and yet very important process of how to pass data in CodeIgniter.

Up and Running with Symfony 3
User handling is a fundamental part of a ton of web projects.  This post will walk through how to get setup using the Symfony 3 framework and the Friends of Symfony bundle so that your project can allow users to register, login and out, and view and edit their User profile. The steps here will serve as a great starting point for your next web project.

A Practical Introduction to Snapshot Testing
The basic idea of snapshot testing is that you compare the output of your code against a file that’s written on disk. That file is called a snapshot. If the output of your test matches up with the contents of that snapshot, it succeeds, otherwise, it fails. It’s as simple as that. In this talk we’ll demo how you can add snapshot testing methods to PHPUnit and review a practical example on how to use them.
