New in Symfony 4.1: Fastest PHP Router
Feb 16, 2018 @ 10:48:33

On the Symfony blog they have a post covering the result of some changes to how the framework handles incoming requests in Symfony 4: a performance and speed increase in the router making it even better than before.

Symfony 4 is the fastest PHP framework according to independent benchmarks, but we are continuously working on making it faster. In Symfony 4.1, we improved the Routing component to make it much faster when matching incoming URLs.

The post starts with a look at the two functional pieces of route handling: the generation of a URL to match and the matching the framework performs. Symfony 4 has sped things up by creating a "matcher" class during the compilation phase using some of these suggestions. The biggest change was to modify the regular expression URL matching to combine all patterns into one, reducing the number of calls to preg_match and locate the correlating route. The new routing requires no changes in your current Symfony 4 application, it just makes all of the updates it needs behind the scenes during compilation.

Symfony Blog:
The end of Silex
Jan 12, 2018 @ 11:28:59

On the Symfony blog there's a quick post from Fabien Potencier (a sort of follow-up to this one) that talks about the end of Silex, a popular Symfony-based microframework, now that Symfony 4 and Flex exist.

What about Silex in a Symfony 4 world? During the last few months, and as an exercise when working on Flex, I have migrated several applications from Silex to Symfony 4. And the conclusion is that Symfony 4 feels like using Silex.

Using Symfony 4 and Flex feels as lightweight as using Silex. [...] Moving away from Silex is also made simpler as Symfony 4 almost auto-configure all your services. [...] For all these reasons, I would say that Silex is not needed anymore. So, we've decided to not support Symfony 4 in Silex, or at least not add the new features added in 3.4.

The comments on the post seem mostly supportive of the decision, realizing that what Symfony 4/Flex bring to the table all but replaces Silex anyway. A migration guide is in the works but hasn't been completed yet at the time of this posting (see this issue for the latest updates on that guide).

Symfony Blog:
The end of the Symfony Standard Edition
Jan 10, 2018 @ 11:54:34

On the Symfony blog there's a post with a major announcement for the users of the framework - the end of the Symfony Standard Edition, a release version that tried to bundle in the common tools a developer might need.

When I started to work on Symfony 2 many moons ago, I decided to create a set of decoupled components instead of a monolith framework like symfony 1. This choice was probably one of the key reasons of the immediate success of Symfony 2. [...] Of course, people don't want to assemble the components themselves when starting a new project. To fill the gap, we created the Flex was born. [...] Thanks to the new Flex approach, we've decided to not provide the Symfony Standard Edition for Symfony 4.0.

In the post Fabien talks about some of the history behind the Standard Edition including why it was made and what problems it solved. He then points out that, with the introduction of Flex, many of the issues and flexibility the SE lacked are worked out. While it is a little more complex to get started with a Flex application, the unpacking functionality helps with bringing in bundles of packages related packages without having to require each individually.

Fabien Potencier:
Symfony 4: Unpack the Packs
Jan 04, 2018 @ 11:53:47

Fabien Potencier of the Symfony project has a post on his site that introduces Symfony Packs, groupings of useful packages that can enhance the functionality of your application without having to manually load each package individually.

We get a lot of positive feedback on Symfony 4. You love the new directory structure. You love the simplicity of using services without configuring anything. And you love the automation that Flex provides. It makes me happy and proud.

[...] But one issue I hear sometimes is that it is more complex to start a new project. [...] You loved the simplicity of starting a project with the Symfony Standard Edition. Is it nostalgia? Perhaps. Would it be possible to get the best of both world? Certainly!

The Packs are "metapackages" that Composer uses to bundle dependencies together that relate either in functionality or as defined by a custom configuration. The article gives an example using the symfony/orm-pack pack and talks about how you can use it as-is or you can "unpack" it into its separate packages and automatically update the composer.json with the result.

Knp University:
The Flex composer.json File
Dec 26, 2017 @ 11:51:50

For those looking to make the move up to Symfony 4 and Flex the Knp University site has a new post that sheds some light on the composer.json configuration for Flex and how to use it to install a complete Symfony 4 application.

We need to make our composer.json file look like the one from symfony/skeleton. Actually, go to "Releases", find the latest release, and then click to browse the files. Now we can see the stable composer.json contents.

So... yea, this one file is all you need to start a new project. That's crazy! Flex builds the project structure around it.

The article then talks about the major changes including dropping the symfony/symfony package, how to synchronize the rest of the composer.json and autoloading updates. It ends with a brief mention of how to then scaffold out the full application structure - one command, a Composer update.

Symfony 4: Performance out of the Box
Dec 12, 2017 @ 13:48:07

In a quick post to his site Fabien Potencier (of Sensio Labs and the Symfony framework) has a post sharing some information around the performance of Symfony 4 and what kind of speed you can expect in your applications based on it.

Performance is an interesting and sensitive topic. Suffice to say that most projects should not care too much; modern PHP frameworks are fast enough for most use cases and projects. And PHP 7 performance improvements help a lot as well. But people like to compare frameworks, and I guess performance is one way to do so.

What about Symfony 4? During its development cycle, we did some nice performance optimizations: mainly to improve the router and container speed. But several non-related changes in Symfony 4 also help with performance... Your mileage may vary depending on your specific project of course.

He talks about some of the testing and evaluation that's already been done on "Hello world" script performance but points out that this isn't a very real world situation. He shares these metrics, however, to at least give a baseline to compare it against previous Symfony versions. The post also links to another resource that shares these and other benchmarks related to various PHP projects.

Jerzy Zawadzki:
Symfony 4: New Hope
Dec 04, 2017 @ 11:16:56

In a new article to his Medium.com site Jerzy Zawadzki talks about why he things that Symfony 4 is "the new hope" for the framework. In the article he goes through the updates in their major version including code examples, commands and descriptions on each.

On November 30, 2017 new version of Symfony Framework has been released and it looks like core team followed the Star Wars numbering pattern, as 4th version is much better, leaving previous three behind as they look like ‘prequels’ now.

In this article, I will try to sum up all important changes made in Symfony 4, so if you are familiar with Symfony 3 and want to get known with new version? - ?this article is for YOU!

He talks about the changes in developer experience that come along with version 4 and updates to the installation process to make it even simpler. He lists out the packages that are installed in this new version and what's included by default. He then walks through the addition of other packages and tools, pulled in as custom options. Finally he talks about bundles, their use in Symfony 4 and the changes in how applications are structured based on their use.

Symfony Finland:
Four things I like about Symfony 4
Nov 28, 2017 @ 12:17:36

On the Symfony Finland site they've posted a new article covering the four things they like about Symfony 4, the next major version of the popular PHP framework.

Symfony 4 launches on November 30th 2017, some two years after the previous major release that was Symfony 3. Symfony 3 can be thought of as a stabilization release with code cleanup, some new functionality and housekeeping Standard Edition (AKA Full Stack Framework).

In the latest incarnation, there are more significant changes, especially to the framework and some key components. Let's take a look at four features that address frustrations that I've had in the past.

The four features in the list are:

  • Simplified project structure
  • Easier installation of extensions
  • Dependency Injection improvements
  • Symfony Encore for asset management

Each section comes with a description of the update and links to other resources where you can find out more information about them. The post wraps up with an overall look at this new version (and Symfony Flex) and how they can improve a Symfony developer's life in the future.

Symfony 4: An Update on Flex
Nov 21, 2017 @ 10:01:46

In a new post to his site Fabien Potencier has posted an update about Symfony 4/Flex and what can be expected from this upcoming release.

Symfony 4 is just around the corner. And Symfony Flex is one of the main selling point for the upgrade. Developers love the new philosophy. And a lot of changes happened since my last blog post. Let me recap the recent changes that you might not be aware of. Most of these changes were prompted by feedback from early adopters.

Included in his list are things like the easier use of recepie contributions, Makefile support changes and minimum PHP version requirements. He also links to an upgrade tutorial and a best practices guide to help you get your application and its code prepared for this new release.

Symfony Flex adoption picks up prior to release of 4.0 in November 2017
Oct 31, 2017 @ 09:55:14

The Symfony Finland site has a new post with a brief look at how the adoption rate of Symfony Flex has picked up with the impending release of Symfony 4 coming next month (November 2017).

With Symfony 4.0 a new standard structure for building applications is being adopted. This is known as Symfony Flex and will be the preferred way of creating applications. Symfony 4.0 is scheduled for release in November 2017, but many projects have already started adopting the new structure.

[...] In six years a lot of things have changed in the web development world, with the rise of front end driven applications, containerised microservices and more. [...] One thing that has not changed for some time is the Standard Edition itself. It has been critiqued for being enterprisey and heavy on configuration. [...] The trend was noticed by the team and in December 2016 at the SymfonyCon Berlin Symfony Flex was announced.

The post also lists out some of the projects that are already embracing Symfony Flex in their project structure including the GraphQL bundle and the PhpStorm Symfony plugin. Symfony Flex also gives developers a way to more immediately work with Symfony 4 when it is released through the same methods as now (with the 3.3 components).
