How to know which version of Symfony I have?

Question

I know that I have downloaded a Symfony2 project and started with but I have updated my vendor several times and I want to know which version of symfony I have

Answer 1

If you want to dynamicallly display your Symfony 2 version in pages, for example in footer, you can do it this way.

Create a service:

Register in service.yml

 dut.twig.symfony_version_extension:
    class: Project\Bundle\DutBundle\Twig\SymfonyVersionExtension
    tags:
        - { name: twig.extension }
    #arguments: []

And you can call it anywhere. In Controller, wrap it in JSON, or in pages example footer

 
 Built With Symfony {{ symfony_version() }} Version MIT License

Now every time you run composer update to update your vendor, symfony version will also automatically update in your template.I know this is overkill but this is how I do it in my projects and it is working.
