NetTuts.com: Laravel, BDD And You: Let's Get Started

On NetTuts.com they've kicked off a new series of tutorials teaching you about Laravel development but using the principles and testing of behavior-driven development (BDD). In this first part of the series they get you started with the basic environment and a few simple tests.

Welcome to this series about developing Laravel applications using a behavior-driven development (BDD) approach. Full stack BDD can seem complicated and intimidating. There are just as many ways of doing it as there are developers. In this series, I will walk you through my approach of using Behat and PhpSpec to design a Laravel application from scratch. There are many resources on BDD in general, but Laravel specific material is hard to find. Therefore, in this series, we will focus more on the Laravel related aspects and less on the general stuff that you can read about many other places.

He talks about what it means to "describe behavior" versus other kinds of testing and introduces the sample application they'll be creating to show these principles: a time tracker. Following this, they help you install the needed tools (via Composer) and initialize the directory to be ready for the Behat/Phpspec tests you'll create. An example of a basic Feature is included, testing the initial Laravel "Welcome" page it defaults to and how to execute it. Finally, following the ideals of BDD, they show how to implement the "Given I am logged in" step first in the test then in the Laravel application.

Phil Sturgeon: What is The League of Extraordinary Packages?

In his latest post Phil Sturgeon talks about a project that's been running for a while, the The League of Extraordinary Packages and aims to clear up some recent misconceptions about the group and what they strive for in the projects they endorse.

This is the story of group of friends, who decided to write some code, but somehow confused and angered everyone with a keyboard. [...] Where should I release this code [I was super excited about releasing]? Should I release it with a vendor name of Sturgeon? That seemed rather egotistical. I could make something up, but what is the point of a single vendor with a single package? I wondered if any of my buddies were having this problem. [...] Being as hungover as I was, I thought long and hard, for about 5 seconds until something amazing happened in my brain... The PHP Super Best Friends Club! The guys loved it, and we started making plans immediately.

He goes on to talk about The League and some of the goals of the organization including the stated desire for quality code and a constant stream of work on the project (no abandoned or stale projects). He talks about how some of the rules for inclusion were created and some of the members of the various projects it includes. He then gets to the "recent misunderstanding" part of things with the clash of the League and the PHP-FIG (see here). He clears up some of the confusion in that thread by stating that:

  • League != PHPClasses
  • League != PEAR

He finishes off the post talking some about the leadership of the group (hint: it's an organization, not really run by a person or persons) and some of the work he's doing to ensure the future of the League and the packages it includes.

Qafoo Blog: Utilize Dynamic Dispatch

On the Qafoo blog today Tobias Schlitt talks about dynamic dispatch, what he calls a "fundamental concept of OOP" to help provide clean, clear interfaces in the code.

I want to use this blog post to illustrate the concept of dynamic dispatch which I use a lot recently to motivate creating clean OO structures in my trainings. In my experience, this helps people to understand why we want to write code in this way. After that I will show why traits are bad in this direction.

He explains the concept of "dynamic dispatch" by starting from the beginning...with procedural PHP code. He looks at the usual flow of this kind of application that call shared functions in a "top down" fashion. He looks at what would happen if new logging needs were introduced (use a new method? patch the current one?) and the dependencies that can be introduced because of it. With this in mind, he continues and talks about how the "dynamic dispatch" happens during the code execution, splitting the log request based on the information it's given instead of different implementations for each. He points out that using a trait doesn't allow for this abstraction and instead embeds the code into the class itself, re-introducing the original problem.

NetTuts.com: Unit Testing Succinctly: Why Unit Test?

NetTuts.com has kicked off a new series of posts today that answers the question "Why unit test?" The series, Unit Testing Succinctly aims to define what unit testing is, approaches to implementing them and what they can do to help you and your application.

The usual mantra we hear regarding any software methodology is that it improves usability and quality, reduces development and testing time, and brings the product to market faster and with fewer bugs. These are lofty goals, but I have yet to see a methodology deliver the Grail of software development. Ultimately, the primary reason to write unit tests is to prove correctness, and this happens only if you write unit tests well.

In this first post they cover three of the more general reasons for making the dive into unit testing your applications at all. These are more "business value" kinds of ideas but they trickle down into the development level, providing value for the developers too.

  • Measuring Correctness
  • Repetition, Repetition, Repetition
  • Code Coverage

Their main point to reinforce is the first of the three, though. Unit testing helps to measure and ensure correctness of both the code itself and the functionality it performs.

Acquia Blog: The Future of PHP is Shared Power Tools

October 17, 2014, 7:06 am

On the Acquia blog there's a recent post from Ryan Weaver from KnpLabs, well known for his contributions to the Symfony2 framework. In his post he suggests that the future of PHP is "shared power tools", less around the monolithic frameworks or installable software and more about the combinations of small pieces of code doing exactly what they need and nothing more.

[Things like Drupal, Joomla and WordPress are] painstakingly thought about and solved the same problems from scratch. And despite that, the results were incredible. How? Because they leveraged the sheer size and passion of their respective PHP communities. But it makes me wonder: what crazy things could we build if we worked together? Fortunately, we're on our way to finding that out. The PHP world is transforming and the individual armies and empires are blurring together.

He talks about how PHP developers should stop fighting the same battles and start working together using existing libraries to solve problems. He points out that applications, even the big names, are becoming more and more modular. Even Drupal has recently made the move to include Symfony packages for some of its functionality (other examples are given too). He also talks about "developer experience" in using these tools, what Symfony is doing to help it and how building on these and other components is essentially "standing on the shoulders of giants" to solve problems easier, faster and with better quality code.

On the main PHP.net site an announcement has been posted about the release of the two latest versions in the PHP 5.4.x and 5.6.x series - PHP 5.4.34 and 5.6.2

These releases fix several bugs in both versions including several security-related issues including CVE-2014-3668, CVE-2014-3669 and CVE-2014-3670. In the 5.4.34 release there was also a fix put in to correct a regression issue in the OpenSSL functionality.

As both of these contain security-related fixes, it's strongly recommended that you upgrade as soon as possible. As always, you can find the latest downloads on the main downloads page or windows.php.net for the Windows users. The full list of changes in each of the versions can be found in the Changelog.

Anthony Ferrara: A Followup To An Open Letter To PHP-FIG

Based on some of the responses to his previous open letter to the PHP-FIG (Framework Interoperability Group), Anthony Ferrara has posted a follow-up explaining some of his points made and the caching proposal in a bit more detail.

A few days ago, I wrote An Open Letter to PHP-FIG. Largely the feedback on it was positive, but not all. So I feel like I do have a few more things to say. What follows is a collection of followups to specific points of contention raised about my post. I'm going to ignore the politics and any non-technical discussion here.

He points out that while the previous post wasn't completely about the cache proposal (it was used as a "literary device") there was some confusion on it. He walks through the "unnecessary complexity" he sees with it, citing code examples, and makes points about performance, memory usage handling stampede protection and the creation of standard ways to avoid it. He ends the post with a look at group invalidation handling and two ways it could be accomplished, either via namespacing or through tagging the items and using that as a reference point for the invalidation.

SitePoint PHP Blog: How to use RabbitMQ with PHP

The SitePoint PHP blog has published a new tutorial today by Miguel Ibarra Romero introducing you to the RabbitMQ queuing tool and shows you how to use it in PHP-based applications via the php-amqplib library.

AMQP (Advanced Message Queueing Protocol) is a network protocol that can deliver messages from one application endpoint to another application endpoint. It does not care about the platform or language of said applications, as long as they support AMQP. [...] The advantage of having a message broker such as RabbitMQ, and AMQP being a network protocol, is that the producer, the broker, and the consumer can live on different physical/virtual servers on different geographic locations.

With some of the introductions out of the way (common terms, flow of the data, etc) he walks through the installation of the RabbitMQ software on your system. He uses a Ubuntu install, but the commands could be easily ported for other distributions. From there he shows how to install the PHP library and a simple example of a pizza ordering system where orders are sent to be processed offline. Complete code is included to make the "SimpleSender" class and push the request out to the queue. With that working, he also shows how to create a SimpleReceiver class that consumes the data from the queue and sends the data to be processed.

Rob Allen: Setting up PHP & MySQL on OS X Yosemite

Rob Allen has posted a quick guide to help you get PHP and MySQL set up on Yosemite, the latest version of Apple's OSX operating system (just released last week).

t's that time again; Apple has shipped a new version of OS X, 10.10 Yosemite. Apple ships PHP 5.5.14 with Yosemite and this is how to set it up from a clean install. However, if you don't want to use the built-in PHP or want to use version 5.6, then these are some alternatives [including the Liip binary package, Homebrew or Zend Server 7.x).

He opts for the Homebrew method, installing it first then getting into the PHP and MySQL packages. This is all done from the command-line, so you'll need to be comfortable there. He includes the commands needed to install PHP, MySQL and Apache along with all configuration changes to make them work together. He also shows how to install Xdebug, PEAR, Composer and the Mcrypt & Intl extensions if needed.

Joshua Thijssen: Deepdive into the symfony2 security component: part 1

On the latest post on his site Joshua Thijssen has kicked off a series taking a deep dive into the Symfony security component, a key piece in the security of Symfony-based applications. In this first part of the series he introduces the component and starts in on some of the features it offers.

Once in a while I like diving into code and see how things work under the hood. And as the symfony2 framework consists of many different components, bundles and bridges, there is a lot to discover. But ultimately, the code itself mostly isn't really as complex as it might seem from the outside world: just like a good magic trick, once unraveled, it all seems very simple and makes sense.

However, this is not true for one of those components: the security component. This black box full of dark magic doesn't like to give up its secrets, and after some (miserably) failed attempts, I am trying to unravel it once more in a few blog posts. Either we achieve complete victory, or fail yet again.. At this point, I will give both fair odds.

He starts off with an overview of the component, pointing out the two main things is handles: authentication and authorization. He also pulls in a few other things to do with security in Symfony to give a more complete, well rounded picture - the component itself, the security bundle and security bridges. He gets into a bit more detail about this last one and describes their specific use.

Qandidate.com Blog: Using the Accept Header to version your API

October 20, 2014, 10:56 am

On the Qandidate.com blog today there's a new tutorial talking about the use of the Accept header in REST HTTP requests and, more specifically, working with it in a Symfony-based application.

I investigated different ways to version a REST API. Most of the sources I found, pretty much all said the same thing. To version any resource on the internet, you should not change the URL. The web isn't versioned, and changing the URL would tell a client there is more than 1 resource. [...] Another thing, and probably even more important, you should always try to make sure your changes are backwards compatible. That would mean there is a lot of thinking involved before the actual API is built, but it can also save you from a big, very big headache. [...] Of course there are always occasions where BC breaks are essential in order to move forward. In this case versioning becomes important. The method that I found, which appears to be the most logical, is by requesting a specific API version using the Accept header.

He shows how to create a "match request" method in his custom Router that makes use of the AcceptHeader handling to grab the header data and parse it down into the type and API version requested. He also includes an example of doing something similar in the Symfony configuration file but hard-coding the condition for the API version by endpoint.

NetTuts.com: Design Patterns: The Facade Pattern

NetTuts.com has continued their series covering common design patterns and their implementation in some example PHP scripts today. In their latest post they focus on the Facade pattern, a member of the "structural" family of patterns.

When it comes to design patterns, you may have questions: Why should we use design patterns in programming? Our code can work just fine without it. [...] Code that employs design patterns is easy to understand, easy to maintain, and easy to extend.[...] In this tutorial, we are going to cover the facade design pattern. It falls under the category of structural patterns because it deals with how your code should be structured to make it easily intelligible and keep it well maintained in the long term.

They start with a UML layout of a typical Facade and include a typical problem/solution where it could be used. They get into a code example that creates a simple checkout process. In this process, they use the Facade pattern to create a more maintainable, extensible ordering workflow.
