Test-driving repository classes - Part 2: Storing and retrieving entities
Oct 08, 2018 @ 14:44:04

Matthias Noback has continued his series of tutorials covering various uses of the Repository design pattern. This is the second part of the series and picks up where part one left of, showing the handling of entities in the repository, performing the usual CRUD operations.

In part 1 of this short series (it's going to end with this article) we covered how you can test-drive the queries in a repository class. Returning query results is only part of the job of a repository though. The other part is to store objects (entities), retrieve them using something like a save() and a getById() method, and possibly delete them. Some people will implement these two jobs in one repository class, some like to use two or even many repositories for this. When you have a separate write and read model (CQRS), the read model repositories will have the querying functionality (e.g. find me all the active products), the write model repositories will have the store/retrieve/delete functionality.

In particular if you write your own mapping code (like I've been doing a lot recently), you need to write some extra tests to verify that the persistence-related activities of your repository function correctly.

He starts with the test cases for the functionality (following the test-drive design mentality) and talks about the expected behavior of the various entity and repository methods. He includes the code for these tests covering state changes, handling child entities, deleting entities, and working with ports/adapters.

Get Started With Pusher - Using Private Channels
Aug 09, 2018 @ 11:56:46

TutsPlus.com has posted the next part of their series covering the use of "channels" with Pusher, the real-time messaging service. In the previous article they introduced Pusher and its "channels" functionality to build a simple real-time chat. In this new tutorial they show how to modify this application to use private channels.

n this series, we've been learning about Channels from Pusher, a platform that allows you to give your users the seamless real-time experience they want.

Private channels provide your applications with a secure, private medium for publishing messages. The best part is how easy it is to implement and use private channels for your apps.

Much like the previous article, they've included a screencast of the entire process right along side the text version. The tutorial walks you through setting up the server (the ChannelsController), the endpoint for client authorization and the changes to make to the client itself.

Pascal Landau:
Setting up PhpStorm with Xdebug for local development on Docker
Aug 08, 2018 @ 12:44:30

Following up from his previous post about setting up Docker running PHP-FPM and Nginx on Windows 10, Pascal Landau has published the second part of the series taking things a step further and introducing (and integrating) PhpStorm and Xdebug for local development debugging.

In the second part of this tutorial series on developing PHP on Docker we're taking a good hard look at PhpStorm, Xdebug and how to run and debug scripts from within PhpStorm on Docker.

[...] The setup that I am going to use is for demonstration purposes only! I do not recommend that you use it "as is" as your development setup. [...] There will be a another part of this series that will deal with all of those (and some more common) problems and aims at providing a consistent development environment for all developers in a team (regardless of the OS they are using).

He then walks through the process from setup through actual script debugging:

  • setting up the Docker containers/configuration
  • allowing the PHP container to connect over port 2375
  • running a PHP script on this container
  • building a "workspace" container for Xdebug

For each step he provides the configuration changes needed, commands and screenshots of the settings panels to ensure its easy to follow along.

An extremely picky developer's take on static site generators for PHP: Part 2 - Jig
Aug 03, 2018 @ 10:50:23

On the Contentful blog they've posted the second part of their series reviewing static site generators for PHP. In this new article they look at Jigsaw, a Laravel-based tool.

In the first article of the series we took a look at Sculpin, the PHP static site generator which is currently the most starred on Github. Today we’re exploring Jigsaw, a tool which promises to bring a Laravel-based approach to the world of PHP static site generators (SSGs).

The author starts by sharing some about his (somewhat limited) experience with Laravel. From there he dives right in, showing the creation of a new Jigsaw site including configuration and how to serve it up locally. It then gets into detail about the directory structure of the site, asset handling and adding new content. The post ends by answering the "is it ready" question for their own needs (at Contentful).

Delicious Brains:
WordPress Deployment Part 2: Deploying WordPress Using The Command Line
Jul 03, 2018 @ 09:48:59

The Delicious Brains site has posted the second part of their "deploying WordPress using the command line" series today. In part one they talked about automated deployments and why they're important (and useful). In this latest tutorial they start in on the setup of the environment and the tools you'll need to complete the deployment.

In my last article, we looked briefly at why automated deployments are important and how to prepare a WordPress site for automated deployments.

Now that our WordPress site is ready to be deployed, in this article we’re going to look at how we can use command line (CLI) tools to deploy WordPress from our local computer to a remote server. While we’re not quite at the stage of being ready to set up automated deployments just yet, understanding how we can use CLI tools to deploy WordPress will serve as a good foundation for all of the automated deployment methods we will look at later in this series.

The article then walks through the different pieces you'll need to set up including a DigitalOcean droplet as a destination and a choice of several data transfer tools:

The post also mentions the WP-CLI tool but points out that it doesn't include functionality to actually move files, only work with local ones.

SitePoint PHP Blog:
Building an Image Gallery Blog with Symfony Flex (Parts 1 & 2)
Jun 21, 2018 @ 11:48:56

On the SitePoint PHP blog they've kicked off a series by Zoran Antolovic walking through the creation of a blog application using the latest from the Symfony project - Symfony Flex.

Our journey towards a stable, robust, high-performance web app will start with the simple but functional application — the so-called minimum viable product (MVP). We’ll populate the database with random content, do some benchmarks and improve performance incrementally. Every article in this series will be a checkpoint on our journey!

This article will cover the basics of setting up the project and organizing files for our Symfony Flex project. I’ll also show you some tips, tricks and helper scripts I’m using for speeding up the development.

So far they've posted the first two articles of the series:

  • Part one explaining some of the basics of Flex and getting the application set up (including some sample fixture data)
  • Part two showing how to populate the application with more realistic data, run some basic performance tests and create a first unit test

There's much more to come in the series including the creation of file (image) upload handling, user registration and login and the creation of image galleries from uploads.

Matt Sparks:
Building a PHP Framework Series (Parts 1-4)
May 16, 2018 @ 12:50:42

On this site Matt Sparks has posted the first few parts of a series covering the creation of a custom framework. Why? Well, as he explains in part one of the series:

So with all of that being said, it begs the question: why on Earth would you want to do this?

The extremely short answer: I want to. The less short answer: A PHP framework encompasses many of the areas I want to learn more about.

The first four posts of the series are already on his site (with more to come):

Matt does a great job of laying out some of the fundamentals behind frameworks including structure, design patterns, and commonalities between frameworks. You can follow along with his progress on the project on the AnalyzePHP GitHub repositories.

Mark Baker:
Discharging Static #2
Apr 05, 2018 @ 10:22:09

Mark Baker continues his series looking at the use of static properties and methods in applications and how to test them. In this second part of the series he focuses more on some of the unintentional side-effects that could happen when you're trying to refactor them out.

In the first article in this series, I wrote about the problems with testing static methods in classes, and showed a few approaches that allow us to write mocks for statics. Testing classes where we have static properties is a lot harder to manage, because any changes made in any test to those properties are global, across the entire test suite, not simply the test that we are running. Static properties are part of the global state, and we can’t simply tearDown() those changes in the way that we do with instances — at least we cannot easily do so if the property has a visibility of private or protected.

He goes through an example of a refactor from a static property (essentially in the global scope) to a private property. He points out the issue of setting a static value in what seem to be separate child classes, the fact that it actually changes the base value, not the individual ones, leading to potentially unintended consequences.

His main recommendation is to avoid the use of static properties all together. Where that's no possible (like in a legacy project) he offers two potential solutions: either replace them with constants if they're never changed or changing them to instance properties.
