Zend-Expressive Console CLI Commands
Feb 12, 2016 @ 11:21:15

In a new post to his site Geert Eltink shares how he added console command support to Zend Expressive, a PSR-7 framework from Zend that recently hit it's v1.0 mark.

zend-expressive does not come out of the box with a console for handling cli commands. However it's easy to add this and make full use of the container and its dependencies.

He uses the Symfony console component to handle most of the "heavy lifting" with the command line interaction, pulled in via Composer. He shows the process for getting the component installed and how to create the "bootstrap" file needed to build an instance of the Application class. He follows this with a simple "greeting" command including the configuration to add a few arguments and output the simple "Hello" message. He then creates the functionality to wire it in to the Zend Expressive application and gives an example of it in use.

What eZ Platform adds to Symfony
Feb 12, 2016 @ 10:44:01

On the Symfony Finland blog Jani Tarvainen has written up a new post sharing some of the things that eZ Platform adds to Symfony and what kind of functionality it brings with it on top of the usual Symfony featureset.

eZ Platform is a Content Management System built with the Symfony Full Stack framework. While this may be clear to developers who have worked with, it maybe somewhat vague for the unitiated, especially when compared with Concrete5 or Drupal, which have adopted Symfony components into their core. [...] The relationship between Symfony and eZ Platform is very similar to Expression Engine using Code Igniter or EPiServer using ASP.NET MVC.

He then goes on to talk about the things Symfony includes by default including the request/response structure, internationalization handling and Twig integration. From there he lists out the things that the eZ Platform adds on top of the standard Symfony including:

  • a content repository
  • dynamic routing
  • a user interface
  • user and permission management

He ends the post with a look at some of the other bundles and features eZ Platform also provides around HTTP caching, image manipulation and more.

The Ultimate Developer Guide to Symfony - Event Dispatcher
Feb 11, 2016 @ 09:29:42

In a recent post to his site Loïc Faugeron has posted the second in his series of in-depth looks at a specific component of the Symfony framework. In this new article he provides the "ultimate developer guide" to the EventDispatcher component.

In this guide we explore the standalone libraries (also known as "Components") provided by Symfony to help us build applications. We've already seen [the] [HTTP Kernel and HTTP Foundation](https://gnugat.github.io/2016/02/03/ultimate-symfony-http-kernel.html). We're now about to check Event Dispatcher, then in the next articles we'll have a look at: routing and YAML, dependency injection and console [functionality].

He starts off with a basic introduction to the EventDispatcher component, describing the EventDispatcherInterface and how to implement the class with simple listeners and dispatch handling. He also shows how to extend this and create Event class implementations. Following this he circled back around to the HttpKernel component and describes how it makes heavy use of events in things like routing, controller requests, exceptions and views. For each he gives a bit of example code defining listeners that perform simple actions when executed.

Marc Morera:
You Probably Need Bundle Dependencies
Feb 10, 2016 @ 09:04:18

In this post to his site Marc Morera responds to some comments from another post about bundles dependencies in Symfony-based applications.

This post tries to answer the Magnus Nordlander’s blog post, and to explain why the Symfony Bundle Dependencies is not just a personal project to fulfill my bundles dependencies, but a practice we should implement in all our Symfony bundles as well.

Believe me, I had a big post to explain why people really need this bundle, but I think that you don’t need these words, but a simple and real example.

He points out a more "real world" example of why this kind of dependency system can be useful in Symfony development. He points out a common service (security.encoder_factory) that's used widely across many bundles, but also defined as a dependency in each. If the bundle dependency structure/tool was in wide use, this dependency would be define elsewhere and not as a part of the bundle itself.

What's on the Menu, Symfony?
Jan 28, 2016 @ 11:49:13

On the Symfony Finland site they've posted a tutorial about Symfony and menus, making use of the KnpMenuBundle to create flexible and easily configured menus with their own renderers.

Menus are a vital part of any web application or a website. Content Management Systems are traditionally a strong contender in this field as they are at their core just tools to create navigatable views to a pool of content. The Symfony Framework on the other hand is neutral when it comes to menus.

[...] There are a number of options for building menus in PHP, but the de-facto standard method for Symfony Framework is the KnpMenuBundle. It uses the KnpMenu library which is an object oriented PHP library for constructing and rendering menus.

The tutorial provides a simple example of using the bundle to create a menu with a handful of options and rendering it with a simple (included) ListRenderer. There's also an example of using a YAML configuration to create the menu and some example code of using a bit more complex and dynamic menu. They also talk a bit about content management systems, their use of menus and which they see as providing a better user experience than the others.

True Dependency Injection with Symfony Components
Jan 20, 2016 @ 10:37:39

On the Toptal.com blog there's a recent post about true dependency injection with Symfony between components in your application and only using the dependency injection container for its intended purpose.

Symfony2, a high performance PHP framework, uses Dependency Injection Container pattern where components provide a dependency injection interface for the DI-container. This allows each component to not care about other dependencies. [...] But this means DI-container can be used as a Service Locator.

[...] In this article we will try to build a Symfony2 application without implementing Service Locator pattern. We will follow one simple rule: only DI-container builder can know about DI-container.

They start off by talking about the structure of the dependency injection container and how it relates to the three main types: controller, method and property injections. He then starts in on creating the sample project and requiring only the Symfony DI, configuration and Yaml components. He then creates a ContainerBuilder class and sets up the HttpKernel functionality to pull the response from the container. He then makes a simple controller with a default action that just responds with text. With this working he updates it to pull in an input variable. He then makes updates to the application with changes to the route handing, templating (Twig), Doctrine (database) and tag handling.

Symfony Benchmarks: Symfony Proxy vs. Varnish
Jan 05, 2016 @ 13:29:51

The Symfony Finland blog site has worked up some benchmarks comparing the Symfony Proxy versus Varnish and shared the results in this new post. The Symfony Proxy is a tool built in to the framework to help with caching responses automatically. Varnish, however, is a separate tool optimized to handle the caching of the same content but outside of the application completely.

In the previous articles we have evaluated PHP performance on different runtimes (PHP 5.6, HHVM, PHP 7) as well as how it behaves when adding server resources (CPU & RAM) using eZ Platform - a CMS built on the Symfony Framework.

In production environments Symfony and eZ Platform are likely ran behind the Varnish Reverse Proxy, which we'll evaluate next by comparing it to the built in Symfony Proxy.

They once again use the eZ platform demo application as the software under test on an 8 Core machine. The results aren't overly surprising if you're familiar with Varnish at all. Software-based caching layers are helpful but when you are able to remove the processing overhead of it from an application, you're better off.

Symfony Benchmarks: PHP 5.6, HHVM 3.11 and PHP 7.0.1
Dec 29, 2015 @ 10:53:46

The Symfony Finland has shared some benchmarks of the latest versions of the Symfony framework (simple applications) on three current environments to see the differences: PHP 5.6, HHVM 3.11 and PHP 7.0.1.

Since the first functional versions of PHP 7.0.0 were made available, there have been a number of benchmarks comparing PHP 5.6, HHVM and PHP 7. [...] The recently released eZ Platform is a CMS built on the Symfony framework. It's a good representation of a modern PHP application with complex functionalities and no legacy code from the 2000's. Thus making a good candidate benchmarks for testing an application built with the Symfony Framework (version 2.7.8).

So let's see how an application built with the Symfony2 framework fares on PHP 5.6, HHVM 3.11 and PHP 7.0.1.

He starts by describing the test setup including the default installation of the eZ platform and how it was configured/set up. He then shares the results, showing memory usage and response times for each of the three different platforms. There's even results from different parts of the application: the front page and the "Top Stories" and "Projects" pages. The results also include the findings for the number of requests per second both with and without the Symfony Proxy included in the platform.

Symfony Blog:
Improving the Symfony Release Process
Dec 11, 2015 @ 10:49:10

On the Symfony blog there's a new post from Javier Eguiluz talking about improvements to the Symfony release process that will be starting with the 3.0.0 stable release (already release so already in place).

The Symfony Release Process is arguably one of the best selling points of the Symfony project. Thanks to our predictable and transparent process, companies can plan years in ahead their Symfony integration.

The recent launch of Symfony 2.8, which will be the last minor version of the 2.x branch, made us think about further tweaks in the release process. That's why during his past SymfonyCon Paris 2015 keynote, Fabien Potencier announced the new Symfony release process.

The main changes for the process are around how many minor versions will be published, standard vs long term support status of these releases and the timing of major/minor releases. With this schedule in place, it's projected that Symfony 4 will be released in November of 2017.

Marc Morera:
Your Packages Dependencies
Dec 04, 2015 @ 10:36:58

In a recent post to his site Marc Morera discusses the topic of package dependencies in PHP applications. While a lot of the concepts and terms he use are more related to Symfony-based applications, the concepts are good and could apply anywhere.

I’m part of this group of people that consider themselves addicts to open source. [...] want to expose my personal experiences about what I learned over the time by leading an open source project, several small open source bundles and PHP libraries, and I want to do it by explaining how we should take care of our Symfony bundles or PHP component dependencies.

He starts by pointing out that he's talking about framework-agnostic packages and their dependencies here (but his own experience is, again, Symfony-centric). He talks about identifying true dependencies through both use statements and composer.json configurations. He points out that the tricky part comes when your dependencies have dependencies and conflicts that may come up because of these relationships. He also talks about another way to identify dependencies (through adapter use) and package versioning problems. He then gets into talking about Symfony bundle dependencies specifically and links to a tool that can help you map out your required packages. He ends the post with a look at development dependencies and the idea of "trust" in the open source software you use.
