How to Setup Docker for Your Symfony Project
Sep 18, 2017 @ 11:48:31

In a tutorial posted to his Medium.com site Dragos Holban continues his series walking you through Symfony for PHP applications. In this latest part of the series he shows you how to use Docker to set up an environment for a Symfony-based application.

As you probably know, I am a big Symfony fan :) In the last few years I used Vagrant to set up my Symfony development environment more or less as described here. But we now have Docker and it’s time to move forward with a new setup. Docker containers are generally more lightweight than Vagrant virtual machines, so starting and stopping them is extremely fast. They also take a lot less disk space.

He starts by sharing an example Dockerfile and docker-compose.yml to help set up and configure the environment to be ready for use. The configuration sets up Apache, PHP 7, MySQL, git, Composer and several PHP extensions. It then installs a fresh instance of Symfony and runs a bash file to finish the setup. He shares the contents of this file and the VirtualHost configuration for the web server. Finally he shows how to run the setup via the Docker command line tool and what you can expect to see when things are running smoothly.

Symfony Console Beyond the Basics – Helpers and Other Tools
Sep 14, 2017 @ 11:12:42

The SitePoint PHP Blog has a new tutorial posted from author Claudio Ribeiro that takes you beyond the basics with the Symfony Console component, showing you how to use some of the helpers and other tools included in its functionality.

It’s undeniable how useful console commands can be when developing software. Not too long ago we re-introduced the Symfony Console component.

This component allows us to create structured and testable CLI commands. We created some simple commands and tested them; but when our commands become bigger and more complex, we need a different set of tools.

This is what we are going to look at today: advanced Symfony console tools.

He then walks you through the installation of the component via Composer and the initial creation of a "FizzBuzz" console command class (and other related classes). He then shows how to use several of the helpers:

  • the "question" helper to ask for user input
  • the "table" helper for outputting structured data
  • the "progress bar" helper to visually output progress of a task

There's also examples included showing how to call a command from inside a command and changing up color and style of the output.

Symfony Blog:
The Symfony Unicorn: 1 Billion Downloads
Sep 12, 2017 @ 12:55:32

On the Symfony blog they talk about a major milestone the framework has reached: one billion downloads of the components that make up the Symfony framework.

A Symfony unicorn!!? It's real! On September 5th, the Symfony Components crossed a huge landmark: the 1 billionth download! This happened less than one year after the last milestone: 500 million downloads. That's right: the PHP community downloaded the Symfony components more than 500 million times in just one year. That's well over 1 million downloads every day!

There are so many people that have made this possible, and we would like to thank all of you who have supported Symfony: developers, contributors, companies, evangelists and - of course - users! There are now over 80 Symfony packages and 1,500 people have contributed code to these. None of this is possible without your help. Congrats!

The post then talks about the current state of the components (including their download numbers), their backwards compatibility promise and how it relates to the upcoming Symfony 4 release.

Symfony OAuth Authentication for Your Mobile Application
Sep 11, 2017 @ 12:57:13

On his Medium site Dragos Holban has a new tutorial posted as a part of his "Learn Symfony 2.8" series. This time he shows how to use Symfony OAuth authentication for a mobile application.

Let’s say you built an API using Symfony and you need to access it from a mobile application using authenticated requests on behalf of your users.

Here’s how to make this work using Symfony 2.8 and Doctrine.

He starts by helping you install the FOSOAuthServerBundle and how to enable it in your Symfony application's configuration. He then includes the code for the OAuth classes: the client and entities for the access token and access token handler. He shows how to configure the bundle and add in routing and configure security protection for the parts of your application. Next he shows the creation of a client and how to document your API using the NelmioApiDocBundle.

Ruslan Karimov:
Using custom types in Symfony & Doctrine
Sep 08, 2017 @ 11:30:26

Ruslan Karimov has written up a post for the 4xxi.com blog covering the use of custom types with Symfony and Doctrine to implement features specific to your database of choice.

ORMs are great. In theory, they insure you against potential changes in your RDBMS and offer an easy plug’n’play solution for integration your domain code with database. In practice, however, since ORMs have to be compatible with all major vendors, their possibilities are often limited. Perks and tricks of specific RDBMS are left out.

One of such perks is so-called range types in PostgreSQL. There are plenty of cases when range types are applicable, but people (in my experience) often stick to old solution with two separate DATETIME columns. Last time I asked a fellow developer about the reason behind it and they said: ‘I use Doctrine in my project, and Doctrine does not support it’. So here we are.

He starts with a brief introduction to a custom type in Doctrine and a ranged type in PostgreSQL. He then shows how to create a custom "DateReangeType" to work with the ranged types and how add it to your Symfony configuration as a custom type. He ends the post with an example of it in use in an entity and in the client code making the database request. Full code can be found in this Github repository.

Martin Hujer:
Don't Use Entities in Symfony Forms. Use Custom Data Objects Instead
Aug 28, 2017 @ 10:53:14

In this post to his site Martin Hujer suggests that you don't use entities directly in your Symfony forms, opting instead for custom functionality to persist form data.

Let's start with stating that using entities for validation in Symfony Forms is widely used and widely recommend approach. Even the official documentation suggests it.

And I don't think it is a good idea! Why? [Three reasons:] an entity should be always valid, change [in the future and] layers separation.

For each of these downfalls he gets into a bit of detail about what the issue is and introduces the alternative: a custom data class. This class is then used to represent the data in the form with some simple assertions. He includes an example of this kind of class with three properties: title, content and public date. He then shows how to build a form using this class and how to handle updates, not just creates, with the same functionality.

Laravel News:
Writing Custom Laravel Artisan Commands
Aug 09, 2017 @ 12:20:29

On the Laravel News site they've posted a tutorial showing you how to create custom Artisan commands making them available right along with the built-in framework commands.

I’ve written console commands in many different languages, including Node.js, Golang, PHP, and straight up bash. In my experience, the Symfony console component is one of the best-built console libraries in existence—in any language.

Laravel’s artisan command line interface (CLI) extends Symfony’s Console component, with some added conveniences and shortcuts. Follow along if you want to learn how to create some kick-butt custom commands for your Laravel applications.

The tutorial starts off with an overview of the current command structure and how a basic Symfony Console command is structured (code). They then get into the creation of their custom command - a "health check" command - by creating a new Laravel project and using the "make:command" command to build out the skeleton code for you. They add the command into the current config and show output of how it should now show in the "help" listing. From there the tutorial shows how to implement the HTTP checking with Goutte and how ot run it on a schedule, writing the result of the check to a log.

SitePoint PHP Blog:
Introducing the Neo4j Symfony Bundle
Aug 07, 2017 @ 13:25:34

On the SitePoint PHP blog they've posted a tutorial from author Tobias Nyholm introducing the Neo4j bundle for Symfony-based application. This bundle provides functionality to work with Neo4j graph databases natively in the application.

There is no such thing as disconnected information, no matter where you look – people, events, places, things, documents, applications and the information about them is all heavily connected. As the volume of data grows, so does the number and dynamicity of its connections. And if you’ve tried in the past to store and query that highly connected, semi-structured data in any database, you probably experienced a lot of challenges.

The tutorial talks some about graph databases, how they work and what kind of data fits into them best. It also briefly covers the Cypher Query Language followed by an introduction to the bundle and what it has to offer. Code examples of putting the bundle to use for queries are provided including the models to handle the results, relationships and an example application you can use to start with a working example.

Matthias Noback:
Layers, ports & adapters
Aug 04, 2017 @ 11:43:11

Matthias Noback has a series of posts on his site sharing some of his thoughts around layers, ports and adapters in application architecture:

Looking back at my old blog posts, I think it's good to write down a more balanced view on application architecture than the one that speaks from some of the older posts from 2013 and 2014. Before I do, I allow myself a quick self-centered trip down memory lane.

He's posted all three parts of the series, each providing either some background on him and his previous work or principles and architecture suggestions:

Each part includes code and/or structure suggestions to help clarify points made along the way.

The CFP process for SymfonyCon and SymfonyLive events
Aug 01, 2017 @ 09:17:41

On the Symfony blog they've shared a post giving you an "inside look" at their Call for Papers process for the SymfonyCon and SymfonyLife events. Each conference is different and has a different process for attracting speakers and selecting them once the Call for Papers has completed.

All the Symfony conferences we organize are aimed at gathering the Symfony community together to enable every community member to meet each other, share best practices and learn tips and about new features. This all happens in a convivial atmosphere that feels like a big family reunion. The highlight, of course, is listening to high quality talks. The speaker line up is very important to us and we take great care to make sure the talks we select will be appreciated and useful for the majority of conference attendees.

[...] The CFP criteria are available online and are the same for all the conferences: we're looking for the best Symfony-focused topics that are relevant to the community. We don't select speakers based on any racial, gender or physical criteria: all the talk proposals received are studied no matter who the speaker is.

They talk about what they provide to speakers, how they review the talks once the CFP is complete and some about the committee that does the selection. With the speakers they want selected they then send out the acceptance notifications and confirm schedules. The post finishes up talking about their emphasis on trying to improve the ration of female to male speakers and their code of contact.
