SitePoint PHP Blog:
Clean Code Architecture and Test Driven Development in PHP
Feb 09, 2016 @ 09:13:28

The SitePoint PHP blog has an article posted by Vitalij Mik showing you how to merge the concepts of "clean code architecture" and test-driven development to make solid, maintainable code. The ideals of the "clean code architecture" were first proposed by Robert C. Martin in this post on the 8thlight blog.

The idea was to create an architecture which is independent of any external agency. Your business logic should not be coupled to a framework, a database, or to the web itself. [...] Frameworks will continue to change and evolve. With composer, it is easy to install and replace packages, but it is also easy to abandon a package (composer even has the option to mark a package as abandoned), so it is easy to make “the wrong choice”.

In this tutorial, I will show you how we can implement the Clean Code Architecture in PHP, in order to be in control of our own logic, without being dependent on external providers, but while still using them. We will create a simple guestbook application.

He starts with a first test, evaluating that a list of entries for the guestbook is empty. The code shows the "fakes" for the different object types Uncle Bob recommended in his article and how it fails because none of them exist yet. He extends this with a "can see entries" test and then starts in on the "use case" class to start making the test pass. He updates the case to pull in entries from the repository, another external dependency created later in the tutorial. He then goes through creating the classes for the "fakes" in the test and refactoring the test based on some of his changes during their development. In the remainder of the post he talks about the independence of the current setup and how to add in pagination functionality on the entries objects.

SitePoint PHP Blog:
Setting up PHP 7 Servers with Laravel Forge and DigitalOcean
Jan 07, 2016 @ 11:11:38

The SitePoint PHP blog has another new article from editor Bruno Skvorc showing you how to set up PHP 7 servers in two different ways: one the DigitalOcean platform and the other using the Laravel Forge service.

In this quick guide, we’ll cover two ways to bring a PHP 7 server online on DigitalOcean – a popular VPS provider. We’ll use two approaches, the latter of which will be applicable to any Ubuntu installation whereas the former will only work on DigitalOcean.

He starts with a brief description of what Laravel Forge is for those not familiar with it and how to use it to set up your new server instance. Screenshots of the interface are included showing the setup of the instance, backups, configuration of the server and how to link it to a repository. Then he gets into the more "manual" installation, working with a simple low-tier DigitalOcean droplet to secure and configure it with similar kinds of features: PHP 7 installed and working, Nginx and a fresh checkout of the repository.

NetTuts:
Doctrine ORM and Laravel 5
Nov 19, 2015 @ 10:55:39

On the NetTuts site there's a tutorial posted helping you get familiar with Doctrine 2 (the ORM) and how to integrate it with a Laravel 5 application via a simple service provider.

As a PHP developer, you might have come across the term ORM. ORM is a way to work with databases in the same way you work with classes and objects. If you were to delve deeper into how web applications are designed and built, after doing some exploring in their ORM you would find two well-known patterns: Active Record and Data Mapper.

[...] With Data Mapper the in-memory objects needn’t know that there is even a database present. They need no SQL interface code or knowledge of the database schema. One such solution is Doctrine.

The tutorial walks you through some of the basic concepts in using the Doctrine 2 ORM including Entities and Repositories. Also included is how to pull it in via Composer and update your Laravel configuration to use this bridge library for integrating it into your current application. Code examples are included showing you how to build out an entity, repository and a validator class for a basic blog post.

Jon LeMaitre:
Separation of Concerns with Laravel’s Eloquent (Series)
Nov 10, 2015 @ 09:10:47

Jon LeMaitre has written up a series of posts talking about effective separation of concerns using Eloquent, the database access component of the Laravel framework. His goal is to show you how makes use of the library and keep your application both maintainable and readable.

Eloquent (and by extension, Laravel) is often criticized because of its ActiveRecord ORM implementation, and that DataMapper produces a cleaner, more maintainable architecture in the long run. [...] This combination of behaviors crammed into a single object in itself is not the problem (in fact, it’s a wonderful asset), the problem is in how you make use of those behaviors throughout your application. You can be sloppy with them, or you can be tidy with them.

He starts with the "sloppy approach" where different methods of accessing the objects (and their data) are spread all across the application. He counters this with the tidy approach that makes use of "persistence-agnostic 'POPOs'" to hide the logic behind repositories. In the second part of the series he starts in and puts this idea into practice, using a simple "Member" table and model and repository classes to abstract the logic. Finally, in part three he gets into some more extended functionality for the repositories approach: handling collections, relations, eager loading and schema changes.

Barry vd. Heuvel:
Using local repositories to easily install private Magento extensions with Compose
Sep 22, 2015 @ 09:02:26

In a post over on Medium.com Barry vd. Heuvel shows you how to use a recently added feature of Composer, the ability to use local repositories, to install Magento extensions quickly and easily.

I’m a fan of using Composer (in- and outside Magento), so I like to use that option. This works great for free packages listed on Magento connect or Firegento Packages, because you can just require the packages and run composer update. [...] This is all great for public packages, which are download through the Firegento repository. But what about private packages? Ideally we could also use Composer for the packages we purchase. [...] In this blog I’d like to explain how to tackle these 2 problems, so you can keep using the Composer workflow.

He walks you through the two steps you'll need to set up the module so it can be installed via Composer: creating a mapping (package.xml) and the composer.json. For the first he recommends using the Magerun modman tool to help with this. Creating/updating thecomposer.json file to work with the extensions is relatively easy. He makes use of the "path repositories" functionality to points the package at the "extensions/" directory using wildcards in the path name to allow for inclusion of all extensions without having to list each one (see this PR). Finally, to help make the process a bit more clear, he walks through a full example using the Amasty module.

Knp University:
Our favorite PhpStorm Live Templates: Share yours
Aug 21, 2015 @ 10:49:39

The Knp University site has a posted an article where they've shared their favorite PHPStorm Live templates, a set of handy shortcuts that can make for less typing on your part and, as a result, less development time spent on common keystrokes.

Most editors have a feature like this, and if you’re not leveraging them, you’re slowing yourself down. Seriously: taking a few minutes to get into these now could add up to a lot of hours saved in the future. The vim users at KnpLabs love this kind of stuff, and have published their own snippets (docteurklein, PedroTroller, Einenlum).

In our tutorial about live templates, we turn formhandle into a snippet that types about 10 lines of form-handling boilerplate code from 10 characters of text. So I started wondering: what are some other awesome live templates we should all be using?

To this end, they've created a repository to store some of these helpful shortcuts. Their list so far includes shortcuts for a 404 if statement, several Twig tags, several for use in a controller context and YAML formatting. The repository includes instructions on how to install the shortcuts and how to include only the ones you want.

New "remi-php70" repository
Jul 24, 2015 @ 12:09:05

Remi has announced the release of the remi-php7 repo, available for Fedora ≥ 21 and Enterprise Linux ≥ 6.

Current version is PHP 7.0.0beta2 with about 25 extensions which are already compatible. This repository provides development versions which are not suitable for production usage. [...] As for other remi's repositories, it is disabled by default, so the update is an administrator choice.

This repository can be installed just like other similar remi repos via the "yum" command to add the repository to the list of available ones, then another to upgrade the PHP installation.

Satis: building your own Composer repository
Apr 30, 2015 @ 11:26:53

Composer has definitely made a huge impact on how PHP packages and libraries are integrated into other applications. Sometimes, though, it makes more sense for you to keep your code internal to the organization rather than have it public where Composer can install it. In this case, using some thing like Satis (a self-hosted Packagist-ish server) makes more sense.

We all love Composer. It changed dramatically the way we build PHP applications, based on small and reusable components, but this creates new challenges, especially when we have a single point of failure (SPO). With Satis, the deployment process can be made robust by adding redundancy in all potential SPOFs (Packagist and GitHub). Let’s see how it works.

They start with a brief look at how Composer works for those not familiar, making the connection with Packagist and ultimately the public repository. In the context of the "single point of failure" they talk about Packagist being down and it preventing the install (or deployment!) of your application. Satis is prefect to help prevent this. The article then shows how to install Satis (via Composer, naturally) and how to set up the configuration file to define the repositories. The server is then built and can be run using the built-in PHP server on the port of your choice. They include a screenshot of the end result and a quick example of how to use it via your project's Composer configuration.

Phillip Shipley:
Creating a PHP Nexmo API Client using Guzzle Web Service Client – Part 3.5
Apr 13, 2015 @ 11:14:29

Phillip Shipley has continued his series about hooking your PHP application into the Nexmo API with this new update, part 3.5 of the series. It's a smaller follow up to the code and functionality introduced in part three with a quick implementation of some of the other API methods.

As I’ve hit on several times, using the Guzzle Web Service description way of developing an API client can save a lot of time. It took me a little less than an hour to finish adding support for these three sets of APIs. If I was writing every Guzzle client initialization and call individually it would have taken a lot longer I’m sure.

The process only takes four steps and the majority of that is just setup via Composer. In order to make things easier and so that you don't have to worry about the details of implementing each of the API features, he's just created a repository to bring all of that functionality in at once. He includes the code you'll need to add to use it as well (about the same as before, just with different client types).

Remi Collet:
PHP 7.0 as Software Collection
Mar 26, 2015 @ 10:15:48

Remi Collet has a new post today talking about the next major release of the PHP language - PHP 7 - and how it, in its current state, can be installed now as an RPM from the "remi" repository as a software collection.

RPM of upcoming major version of PHP 7.0, are available in remi repository for Fedora 20, 21, 22 and Enterprise Linux 6, 7 (RHEL, CentOS, ...) in a fresh new Software Collection (php70) allowing its installation beside the system version. As I strongly believe in SCL potential to provide a simple way to allow installation of various versions simultaneously, and as I think it is useful to offer this feature to allow developers to test their applications, to allow sysadmin to prepare a migration or simply to use this version for some specific application, I decide to create this new SCL.

Instructions for the installation (via yum) are included and a list of some things "to be noticed" about the setup are also included.
