Learn Symfony with online courses and programs

Symfony is a free, open-source PHP web framework that can help developers build reliable web applications. Learn how to use Symfony for efficient web development with online courses delivered through edX.

What is Symfony?

Symfony is an open-source PHP framework and collection of reusable components used for building robust and complex web applications. ‌It includes tools to help developers build, test, and maintain applications. Symfony follows the model–view–controller (MVC) architectural pattern, which structures apps into three connected parts:Footnote 1

  • The model, which handles data and database-related tasks 

  • The view, which represents how the data is presented to the user

  • The controller, which handles the logic between the model and the view 

Developers who use Symfony can also benefit from a large, active community. Contributors support new users and ensure the framework keeps up with the latest trends. Web developers of all levels can use Symfony in their work to make applications scalable and maximize their efficiency.

Symfony tutorial curriculum

For users new to learning Symfony, an entry-level Symfony course can cover foundational topics, such as MVC architecture and how to install Symfony on your local machine. You might then learn how to build your first Symfony application, with accompanying lessons on how to:

  • Use routes to manage user input and create controllers to handle varying user requests.

  • Work with Doctrine‌, the official Symfony object-relational mapper (ORM). This may also include aspects like creating, reading, and deleting database operations.

  • Use Twig, the default templating engine in Symfony, to create secure and reusable views.

  • Implement security in Symfony, including user authentication, encoding and decoding, and implementing permissions to authorize and restrict access to different parts of the application. 

  • Create, render, and validate forms, handle ‌submission of forms, and work with data from the controllers and views. 

  • Use Symfony to integrate with a PHP testing framework. The course may also cover how to handle errors in Symfony and how to provide better error messages. 

Learning how to use Symfony can supplement your knowledge of software development and computer science. edX offers a variety of educational opportunities for learners interested in studying these topics. A coding boot camp can provide flexible, hands-on learning for those who want to gain relevant industry skills quickly, while executive education courses are designed for busy professional schedules. You can also pursue a more comprehensive curriculum in a bachelor’s degree program or, for more advanced learners, a master’s degree program. Find the right learning path for you.

Explore jobs that use Symfony 

Many professionals, including web developers, cybersecurity specialists, and software engineers, use Symfony to develop secure, fast, complete, and robust web applications and customized IT solutions. Paired with specialized knowledge, experience with Symfony can be helpful for a number of job roles, including:

  • Software developer: Builds and maintains software, such as Symfony web-based applications. This can include tasks like designing web interfaces and working with a database to develop the application’s back end.Footnote 2 Employers might seek out Symfony developers who specialize in this framework specifically.

  • Cybersecurity specialist: Detects and prevents web attacks and security vulnerabilities, like SQL injection and cross-site scripting. They may help ensure the security of web applications, including those developed with Symfony.Footnote 3

  • Cryptographer: Develops secure communication protocols and implements encryption and decryption algorithms to protect data against unauthorized access. This is vital to any website or application that handles sensitive information, such as financial data or personal records.Footnote 4

  • Technical lead: Oversees projects, manages a team of developers, and ensures projects meet requirements and are delivered on time. The role requires a deep understanding of technical tools such as the Symfony framework and how the various components work.Footnote 5

Each of these roles will have different educational and skill requirements. For example, you may be able to build relevant skills in a boot camp. However, some employers may seek candidates with a bachelor’s degree in computer science or a similar topic, depending on the role. Before deciding on a specific learning path, research the positions you hope to pursue and align your coursework with your career goals.
