Dependencies in Disguise
Sep 28, 2015 @ 08:48:27

On the PHP.cc's site has an article that looks at dependencies in disguise based on a "workshop" one of their members, Stefan Priebsch, gave at the recent Bulgaria PHP Conference.

Yesterday I gave a presentation at the [Bulgaria PHP Conference](https://thephp.cc/dates/2015/09/bulgaria-php-conference) (a great event, by the way). Following an [ad-hoc workshop](https://twitter.com/s_bergmann/status/647732967087939584) that I gave as part of the hallway track and an entertaining hackathon, I decided it was too late to join the party and went back to the hotel with some other speakers. Checking out how the day was reflected in social media, I contributed a few more tweets to a [conversation](https://twitter.com/tim_bezhashvyly/status/647861115721003008) that had started earlier in the day ([here](https://thephp.cc/dates/2015/09/bulgaria-php-conference/solid-mvc) are the slides of my talk that people are referring to). I am writing this to clarify my point, and help everybody to understand better.

He talks about dependency injection as a best practice that's followed in libraries all over the PHP ecosystem, making it easier to work with objects and their needs. Sometimes this means using a dependency injection container and others it's just constructor/method injection. He talks about how these objects are build in factory methods and recommends making one factory but points out that this only really works when all the objects you need are known up front. However, he gives several (code) examples of places where this could be difficult and how some are using service locators to solve the problem. He points out, however, that this then expands the API of the application out way too far, opening it up to objects all across the application when there may be no need. This is where the hidden dependencies can come in, things masked behind the use of a single service locator. He recommends solving the issue with more customized locators, as in his example of routing locator used to handle dependencies for a POST HTTP request.

Matthew Weier O'Phinney:
On 10 Years at Zend
Sep 21, 2015 @ 17:53:36

Matthew Weier O'Phinney has spent the last ten years of his career working for Zend as a part of their Zend Framework team. In this post to his site he looks back over the years, how it all started and where he is today.

10 years ago, as I write this, I was on a plane from Burlington, VT, to San Jose, CA, where I'd be starting work at Zend Technologies the next day as a PHP Developer.

He talks about where he started out at Zend (the eBiz team) and the kind of work he was given. It was early on that he started working with an internal, new project at the time: Zend Framework. He looks at some of his early contributions to the project and his "trial by fire" when he was asked to help give a tutorial about it at that year's ZendCon. He also mentions some of the people he's worked with along the way and gives thanks to the founding Zend team. Zend Framework was one of the first major frameworks out there and paved the way for the framework-driven environment we find ourselves in now. With Zend Framework v2 it encouraged a component-based system that spread quickly across the entire PHP community. Thank you Matthew for all of your hard work over the years, not just in the Zend Framework ecosystem but in the PHP community as a whole.

Allan MacGregor:
TDD is not Dead
Sep 08, 2015 @ 10:30:01

Allan MacGregor has a post to his site with some of his thoughts on why TDD isn't dead and is still a viable option to help reduce bugs and improve software quality.

So, where does this whole TDD is DEAD thing came from? Well, it all started with let's say a provocative talk and follow up blog post by David Heinemeier Hansson (@DHH) where he expressed his frustration with testing and put into question the value of TDD. [...] TDD is not dead, not really. And it won't really ever be dead, it will change or be replaced with something better; in fact it already has, and in my Magento Extension Test Driven Development book we focus on Behavior Driven Development, an approach that emerged from the original TDD methodology.

He goes through each of the points that DHH mentions in his post and offers some of his own thoughts on the topic:

  • Developers make you feel like your is dirty if you don't practice TDD
  • Driving design from unit tests is not a good idea
  • TDD notion of "fast tests" is shortsighted
  • 100% coverage is silly.
  • TDD created test-induced design damage.

He ends with the most common misconception about testing in general too: i"t's too much work/it will make my development slower." He also looks at some of these kinds of comments specifically targeted at Magento 2.

Testing myths debunked
Aug 12, 2015 @ 11:20:14

The Inviqa blog has posted an article that seeks to debunk some common testing myths when it comes to ensuring quality in software development (and its results). They cover eleven different points with a rebuttal for each, refuting them as excuses and possible misunderstandings.

Software testing has been around for many years now but over this time some incorrect assumptions have arisen about what testing is, what the process involves and how the process of testing can add value to the software development process. Here we take a look at some of the more common myths about testing and, from a tester’s point of view, provide correct and valid information for each point.

Among the myths they cover are things like:

  • "Bugs come from lazy developers"
  • "If we test it for long enough, we’ll catch all of the bugs"
  • "Developers and testers are like cat and dog"
  • "Testing is boring"
  • "We don’t need testers"

Each includes a paragraph or two of content pointing out the problems with the statement and offering some constructive ways to help solve it in your organization.

How to set up your Mac for local PHP Development
Aug 05, 2015 @ 10:48:14

Eric Barnes has posted a guide to helping you set up (as he sees it) a good PHP development environment on your Mac that includes Homebrew for package management, Composer, Vagrant and the Laravel Homestead VM for project hosting.

This past weekend I decided it was finally time to wipe my Macbook’s hard drive and start fresh. I have used it daily for several years now and still had artifacts from when I used Mamp. Since then Vagrant has turned to my local server of choice and one of the reasons is how clean you can keep your machine by utilizing it.

After finishing the new Mac OS X install it felt like a new beginning. So clean, so minimal. [...] This go around I wanted to keep it as minimal as possible and only install things I know I need and use. This tutorial covers how I set up my Mac for local PHP Development.

His list of software includes the previously mentioned four as well as the ZSH shell replacing the default bash and, obviously, PHP itself installed via Homebrew.

How I develop in PHP with CoreOS and Docker
Jul 29, 2015 @ 11:41:14

Joeri Verdeyen has posted a tutorial showing you how to use a combination of CoreOS and Docker as a PHP development environment. This is an alternative to the more frequently used Vagrant VM provisioning popular among developers.

I’ve been using the Vagrant provisioned-with-Ansible-setup for a while now. But for the last month(s) I’ve been playing around with things like: Docker, boot2docker, CoreOS, etcd, .. I managed to setup a fast and easy way to develop my PHP applications. Symfony2 is my preferred weapon of choice, so I’ll explain how I’m developing a Symfony2 app.

He starts with the software you'll need installed to get his example up and running, all installable via "brew". He shows how to configure the CoreOS via Vagrant and bring the box up. He then sets up the Docker client to point to the newly created VM as its server. He then creates a docker-compose.yml file to set up the necessary services including nginx, MySQL and (of course) PHP. He then shows the command to run the container, execute the configuration and ensure that all containers are configured correctly. Finally he runs the Composer installation command (Symfony2, remember) and clear the cache.

The WordPress Plugin Boilerplate Part 2: Developing a Plugin
Jun 30, 2015 @ 10:07:50

The SitePoint WordPress blog has posted the second part of their series covering the creation of a WordPress plugin with the help of the WordPress Plugin Boilerplate. In this latest article they build on the first part of the series and start in on the actual plugin development.

In the first part of my series, an introduction to the WordPress Plugin Boilerplate, we looked at how the code is organised within the Boilerplate. To continue with this series, we’ll apply what we’ve learnt previously to build a real working plugin. We are going to take a look at how quickly we can get our plugin up and running using the Boilerplate code, with as little work as possible. This article will focus on creating and activating the plugin, as well as developing the admin facing functionality of the plugin.

They show you how to create a simple "time since posted" plugin with a few customizations available. They show how to use the Boilerplate generator to set up the basic plugin file structure and installing it on your WordPress application. From there they show you how to create a simple "Settings" page for the plugin and making it work via the functionality Boilerplate offers. The post then shows how to register the plugin, populate the options page and saving the changes the user makes.

Building a Custom Twig Filter the TDD Way
Jun 08, 2015 @ 13:40:18

The SitePoint PHP blog has a new tutorial posted showing you how to create your own Twig template following a TDD (test-driven development) mentality.

Twig is a powerful, yet easy to master template engine. It is also my personal favorite as all my web development is based on either Symfony or Silex. Apart from its core syntax ({{ ... }} and {% ... %}), Twig has built-in support for various filters. A filter is like a “converter”. It receives certain original data (a string, a number, a date, etc) and by applying a conversion, outputs the data in a new form (as a string, a number, a date, etc).

He starts with a brief introduction to what filters in Twig are and some simple ways to use them. From there he gets into building a custom filter, starting with the tests first (hence the test-driven design). He walks you through the creation of a filter that turns times into relative strings, like "Just now" or "Within an hour". He shows how to make the extension classes and integrate it into a Symfony application.

10 Pillars of Modern PHP Development
Jun 04, 2015 @ 08:27:50

On the Fortrabbit.com blog today they have a post where they share what they see as the 10 Pillars of PHP Development. It's a set of ten things they see as the most important to consider in a developer's work.

For most of us PHP developers writing applications now compared to ten or so years ago is quite a different endeavor. [...] This has changed in recent years. Classical web sites are becoming more and more the domain of specialized SaaS. [...] So web developers changed themselves by specializing and concentrating on what cannot be automated so easily: web applications. Along with this came a new mindset on how PHP development should be done and what tools should be used.

Their list of ten includes both generic topics (with a few subtopics for explanation) and specific technical items like:

  • Code management
  • Tests
  • Dependencies and modularization
  • Runtime data
  • Deployment

Check out the rest of the post for other "pillars" in their list and explanations for each.

In this recent post to his site Henrik Warne has shared a list of advice around software development and some good practices he's picked up along the way.

Here is my list of heuristics and rules of thumb for software development that I have found useful over the years.

His list includes several points related to a few main categories:

  • Development
  • Troubleshooting
  • Cooperation (personal, not code)
  • Other Miscellaneous Tips

Each main topic has a few sub-topics and each of those includes a brief description (with twenty-two tips in the list overall). There's some great advice in the list as well as some good contributions in the comments, so be sure to read through those too.
