Symfony Station Communiqué - 21 January 2022

By Reuben Walker, 21 January, 2022


Welcome to this week's Symfony Station Communiqué. It's your weekly review of the most essential news in the Symfony and PHP development communities. Take your time and enjoy the items most valuable for you.


Thanks to Javier Eguiluz and Symfony for sharing our last communiqué and newest article in their Week of Symfony.


*Please note that links will open in a new browser window. My opinions, if I present any, will be in bold.




As always, we will start with the official news from Symfony.

Highlight -> "This week, Symfony fixed some issues related to PHP enums and improved the performance when using many environment variables in your application. Meanwhile, the SymfonyWorld Online 2022 Summer Edition conference finished its early bird period, but the Call for Papers is still open, so you can send your proposals until February 14, 2022."

A Week of Symfony #785 (10-16 January 2022)


Symfony announced "we're introducing the new certification exam for Symfony 6. This exam is similar to the existing Symfony certification exams (same exam topics, same number of questions, etc.) but we've revamped the certification contents with many new questions in addition to removing outdated or complicated questions. We've also updated the content so the entire certification exam for Symfony 6 is much easier than before. No trick questions, the entire exam has been redesigned making sure all questions will be easy to understand and easy to answer to."

Introducing the Symfony 6 Certification


They introduced the brand new Webapp pack. "What are the benefits? The main benefit is that a pack is a regular Composer package that you can require in any existing project (even late in the game). That allows to compose your application by using more than one pack. As for code, package composition is almost always better than inheritance. The website skeleton is all about inheritance: philosophically, it extends the base skeleton. You need to use one or the other. On the contrary, the Webapp pack can be included in any set of dependencies, independently of the skeleton that was used to create the project. Think of a pack as being the equivalent of a PHP trait."

Symfony Flex makes it easy to install a package and get everything you need to start working immediately: new config files, changes to .env, Docker configuration and more. The idea is so powerful that symfony/skeleton - the repository used for new Symfony apps - starts empty other than composer.json! Familiar files like src/Kernel.php, bin/console and config/services.yaml are added to your project via recipes.

Starting in symfony/flex 1.18.0 or 2.1.0, a new composer command is now available when you need to update Symfony to a new version: recipes:update. This command is smart: it generates a "diff" between the originally-installed version of recipe and the latest version, then leverages git to apply that patch. In other words, upgrading recipes is as simple and robust as merging two branches together with git! Most of the time the changes apply cleanly. But if they don't, you get a familiar git-style conflict that you can resolve.

Symfony how to get query string values sent by AJAX calls


Oliver de Cramer writes "For over 7 years I have mostly worked on e-commerce projects. Most of them were Magento 1 & 2 projects with a few adventures with other solutions (Drupal commerce 😱).

So when beginning of this summer I was given the opportunity to work on a Sylius project that didn’t sell products, but subscriptions I jumped on the occasion. "

EasyAdmin 4.0.2 has been released, and it includes one of the most requested features by the community: menu badges. These badges are commonly used to display some numeric value next to menu items (e.g. number of notifications, number of new clients, number of invoices pending to be paid, etc.)

New in EasyAdmin 4: Menu Badges


Kévin Dunglas says "version 3 of the popular Doctrine DBAL library has been released at the end of 2020, almost 10 years after the initial release of version 2. In September 2021, Doctrine ORM 2.10 added support for DBAL 3, while still supporting DBAL 2 at the same time.

The upgrade process from DBAL 2 to DBAL 3 is usually straightforward. Most breaking changes impact low-level classes, that aren’t commonly directly manipulated when using the ORM. However, things become more complex if you rely on JSON columns, and you may know that I’m a big user of them!"

Oleg Charnyshevich tells us "one part of my job is a code review, and I started to notice that some of my colleagues can’t get an idea of dependency injection and the service container. As a result, they tend to over-engineering things." He continues with this.

4 ways to inject dependencies in Symfony that you probably don’t know about


Youri Galescot says "some time ago I discovered the TailwindCSS framework created by Adam Wathan and I was seduced by its simplicity and speed of use. My productivity in creating user interfaces and HTML/CSS integration has been really boosted."

Matija Cerovec writes "The strategy design pattern is a behavioral software design pattern that lets you define a family of algorithms, encapsulates them, and selects one from the pool for use during runtime. The algorithms are mutually interchangeable. By using design patterns, you can make your code more flexible, reusable, and maintainable. In this blog, I will show how to use strategy design pattern on Symfony by real-world case."

Freek Van der Herten makes the claim "Ignition is the most beautiful error page for PHP apps. Yesterday, we launched a new major version of Ignition - you can check out all the details in this blog post.

Ignition used to be Laravel specific, but we've now created a framework-agnostic version as well. Let's try using Ignition in a simple Symfony app."

A better error page for Symfony applications


Leo Hajder asks "How often do you have to consume an external API and integrate it into a Symfony application? Let’s see how to do it fast and/or well, and hopefully learn something along the way. For this example, we’re going to take a look at how to get a response from an API endpoint and render the data in a twig template."

Rob Hedgpeth says "The PHP programming language has long been considered a fairly light and simple solution for developers to use to create robust and creative web applications. In fact, that’s as true now as it has ever been as past few versions of PHP have made the language more appealing than ever.

Like many other languages, PHP has the ability to take advantage of the power of MariaDB, and it’s actually a pretty simple and straightforward process."

Dolcer Engineering asks "have you ever worked on micro-services architecture with a lots of services where every one of them is created by different team and with different code standards? Situations like that are never ideal, but sometimes there’s no other choice, and you need to improve what you can. This was the exact problem we encountered."

Frank de Jonge says "using events in a system is great, but how do you know for sure if you've reliably dispatched your events? The transportation of events needs to be done reliably while maintaining overall system consistency, be it eventual or immediately. In a typical setup, a database is used to store information and queues are used to send messages between processes and systems. Often, the events are dispatched directly to the queue in the same action that stores information in the data. This may not seem to be obviously wrong, but there is a potential problem with this approach."

Git hooks are scripts that will run when a certain event occurs in git like git push, git pull, git commit, etc. We can find git hooks at .git/hooks in a particular git repository.

Precommit is a git hook, that triggers custom scripts or commands during the execution of a git commit.

In this article, we will format PHP code using prettier at a time of committing code to git.

Last week, I shared several articles about the challenges of open-source maintenance. This week, I am continuing the theme." As I have said before, if you use an open-source products please contribute to the maintainer(s).


GitHub participated in the White House meeting on open-source cybersecurity. In the post they "outline three themes that the GitHub Policy Team thinks should drive this conversation with policymakers—to help open-source prosperity and sustainability. These themes are only a starting point: if you have thoughts, please get in touch."

Open-source creates value, but how do you measure it?

ZDNet makes this point "Instead of running around like headless chooks because a widely used piece of open source software is maintained by volunteers and has a massive hole in it, imagine paying someone to look after such software properly."

For security alone, we could try paying open-source projects properly


Shawn Hooper says "The problem is when projects get popular. You now end up with software that is used in thousands (millions?) of pieces of software that is at risk of a) its developer either abandoning the project due to new interests, changed life priorities or 2) the employer who was paying for the development work ends the project. "

On Open-Source and Importance of The PHP Foundation


Finally, TechCrunch notes "Most people don’t realize it, but many of the devices and apps you use every day are built on top of open-source software, maintained by one or two developers that aren’t paid for their time, who patch bugs and improve their code to give back to the community or as a passion project."

Open-source developers, who work for free, are discovering they have power
