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 are in app_dev, you can find symfony version at the bottom left corner of the page

Answer 2

Run app/console --version (for Symfony3: bin/console --version), it should give you a pretty good idea. On a random project of mine, the output is:

Symfony version 2.2.0-DEV - app/dev/debug

If you can't access the console, try reading symfony/src/Symfony/Component/HttpKernel/Kernel.php, where the version is hardcoded, for instance:

const VERSION         = '2.2.0';

Just in case you are wondering, console creates an instance of Symfony\Bundle\FrameworkBundle\Console\Application. In this class constructor, it uses Symfony\Component\HttpKernel\Kernel::VERSION to initialize its parent constructor.

Answer 3

if you trying with version symfony

please try with

symfony 2 +

cmd>php app/console --version

symfony 3+

cmd>php bin/console --version

for example

D:project>php bin/console --version

Symfony 3.2.8 (kernel: app, env: dev, debug: true)

Answer 4

also you can check the version of symfony and versions of all other installed packages by running

composer show

or

composer show | grep sonata

to get versions of specific packages like sonata etc.

Answer 5

Another way is to look at the source for Symfony\Component\HttpKernel\Kernel for where const VERSION is defined. Example on GitHub

Locally this would be located in vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php.
