Symfony Framework - A Complete Beginner's Guide

The Symfony roadmap is a great tool for keeping track of what's in store for the platform and where the development team is headed. Regardless, of whether you're a developer who wants to stay up to date, or someone who's just curious about the project, it's useful to know what's going on. Luckily, the community has been working hard to ensure that it's as easy as possible to access the information you need.

Embracing Symfony

The Symfony community has a lot to show for. They have a plethora of useful tools and technologies at their disposal. If you're considering embracing one, you'll want to look into their products and features to see how they stack up.

The Symfony community has been a pioneer in incorporating PHP standards, such as PSR-8. It also has an impressive suite of tools and technologies to aid your development process.

The best part is that there are many ways to get involved. From attending a Symfony conference to joining a user group, there are plenty of ways to make your mark. There are several sizable sub-projects to choose from. For example, a pheature-flags release management system has a number of benefits, including activating and deactivating specific features based on an API key or user-defined triggers.

In fact, the Symfony has been the first major framework to embrace the majority of the PSRs. While it may not be the best framework to use for all applications, it has an impressive suite of tools to help you build your next app.


Embracing a project of this magnitude is no small task, and the Symfony community is doing everything it can to help you succeed. This includes offering documentation to help you understand the nitty gritty of the newest releases. Among the most useful resources are the symfony documentation portal and the symfony community forums. These help you communicate with other Symfony users and developers around the world.

In short, if you're looking to integrate the latest and greatest in PHP technology, Symfony is the way to go. Whether you're starting a new project or updating an existing one, you'll need to know the best practices for Symfony to be successful.

Supporting all released versions of PHP

With the recent speed up of cyberattacks and the emergence of ransomware, it is becoming more necessary to improve application security. Using an open-source software like PHP for your web projects is one of the most important steps in securing your online presence. It also allows you to build robust applications. However, many websites still use outdated versions of PHP.

Symfony is a PHP web application framework. It allows you to build complex, robust applications without worrying about the code. In addition, the framework is designed to replace the repetitive, error-prone code and help you get faster results. By choosing the right version of Symfony, you can take full advantage of its capabilities and set a benchmark with add-on tools.

Symfony follows a time-based release cycle. A major release is released approximately every two years. Major versions are then followed by Long Term Support (LTS) versions. The LTS version will receive fixes for critical bugs.

Minor versions are released approximately every six months. These releases fix reported security issues and include new features. Each minor version is fully supported for a year. If a critical bug is found, the PHP team will provide an additional year of support for the release branch.

Maintained versions are actively maintained. They are the last two minor versions of a current major version. This means you can expect bug fixes and security updates for another year.

PHP release branches are created on an as-needed basis. These branches fix reported security issues and are fully supported for two years. Some release branches may contain several point releases.

While Symfony supports all released versions of PHP, some bundles are not supported. For example, PHP 7.3 is no longer officially supported.

Embracing Laravel

Symfony and Laravel are two popular web application frameworks. Both provide Object-Relational Mapping (ORM) features that map database records to code objects. However, there are differences between the two frameworks.

Symfony is a PHP web application framework that is used to build websites. It provides several components, such as a dependency manager, a URL routing configuration, and an authentication session.

Although Symfony has been around for a while, its popularity continues to grow. Many software companies are relying on it to develop their applications. As a result, it has a huge developer community. Besides, the framework is freely available.

Laravel, on the other hand, has an early market presence and a more attractive appearance. Moreover, it has a simple and expressive syntax. You can also learn the ins and outs of Laravel with the help of its excellent documentation.

Compared to Symfony, Laravel is easier to start. There is no need to install separate packages and configure your development environment. Similarly, Laravel is more reliable and offers faster delivery. The average loading time of a Laravel website is 60 milliseconds.

Laravel also has a modular packaging system. When developing your application, you can make changes to the code in a way that you can easily share with other developers. Moreover, it has a dependency manager that automatically resolves all your dependencies.

Although Laravel is not the most powerful framework out there, it still has a lot of features. For example, it has an integrated profiler that tracks the behavior of your web app on the back-end. Additionally, it supports the ActiveRecord pattern, which allows models to interact with the database.

Laravel vs Symfony

Symfony is one of the most popular PHP frameworks. It allows developers to create robust enterprise level web applications. The project releases a major version every two years.

On the other hand, Laravel was recently moved to a twelve-month major release cycle. Initially, it released a major version every six months. Now, it offers an LTS version that gives users bug fixes for two years.

Both frameworks have their pros and cons. However, it's important to determine whether they're suitable for your project. You'll also want to consider how easy it will be to hire a developer.

Symfony is a more complex platform, and it can take time to get familiar with it. Unless you're already experienced with PHP and have access to experienced developers, you might not have the time to learn all the ins and outs of it.

Unlike Symfony, Laravel has a much simpler syntax. In addition, Laravel uses a lot of built-in features. For example, the framework automatically scans for dependencies and resolves them. Several security features are also built in. These include XSS protection, auto-logging, and cross-site request forgery.

Both frameworks come with Object-Relational Mapping (ORM) capabilities. These allow you to map database records to code objects. Additionally, both frameworks use the ActiveRecord pattern, which lets models interact with a database.

While both of these frameworks are a good choice for developing your web app, they each have their own set of advantages. Picking a winner depends on your final goal. But overall, Laravel is more suitable for smaller projects.

Symfony is better for large-scale, enterprise-level projects. This is because it offers several scalability platforms. Similarly, it provides out-of-the-box solutions for authentication strategies and authorization tools.

Migration to a new version

You can follow the Symfony roadmap to migrate your application to the latest version. This process is a good way to keep your code up-to-date with new features and fixes, and you don't have to rewrite everything. However, it isn't always easy to do. If you have a large legacy code base, it may be more work than it's worth.

The first step in the Symfony roadmap is to prepare your environment. It's important to make sure that your server is up-to-date with the latest versions of Symfony and PHP.

Once you've updated your server, you can check the requirements of your application to see what steps are necessary. In this case, the most important thing is to have a good test suite.

As you're preparing for your migration, don't overlook your libraries. Third-party libraries that you use may have changed depreciation. You may need to upgrade them to keep your application up-to-date.

One of the best ways to ensure that your application will still function is to perform automated tests. Automated tests aren't cheap, but it's a great way to be sure that everything works.

You can also use the eZ Migration Bundle, which will create compled data migrations for you. However, CRM_Core_Page isn't included in this bundle.

Another tool that's aimed at helping you to upgrade your code to a newer version of Symfony is Flex. This is an automated configuration tool, which can be very useful when upgrading to the latest version of Symfony.

If you're planning to move your application to Symfony, make sure to take some time to understand the changes in the new version. These changes often have major implications, so you'll want to be prepared.
