This can be done in many ways. here are the some of them

if you are a console lover ( this will give you all the files having symfony version hard coded in files)

grep -r VERSION . | grep  ./vendor/symfony/http-kernel/Kernel.php

There are other solution using composer (which will give minor details also)

 composer info symfony/yaml

If you don't have access the console, read file, there is hard coded version

HttpKernel/Kernel.php

For shorter details

php bin/console --version

For Details (e.g. Symfony & PHP versions, Log directory, End of Life.... )

php bin/console about

This page is the top Google result for search which version symfony using, and the top answers probably don't work anymore.

Apparently I'm on Symfony 5, after running symfony new aqua_note (from SymfonyCasts recommendation).

I had to ultimately run grep -r VERSION . | grep Kernel to see ./vendor/symfony/http-kernel/Kernel.php: public const VERSION = '5.4.2';... at least I think that's correct now.

Maybe the anwswers here are obsolete... in any case, for me running Symfony 4, it is easy Just type symfony -V from the command line.

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:

<?php

namespace Project\Bundle\DuBundle\Twig;

class SymfonyVersionExtension extends \Twig_Extension
{


 public function getFunctions()
 {
 return array(
 //this is the name of the function you will use in twig
 new \Twig_SimpleFunction('symfony_version', array($this, 'b'))
   );
 }

public function getName()
{
//return 'number_employees';
 return 'symfony_version_extension';
}   

public function b()
{
 $symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
 return $symfony_version;
}
}

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

 <p> Built With Symfony {{ symfony_version() }} Version MIT License</p>

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.

Although there are already many good answers I'd like to add an option that hasn't been mentioned. Using the command:

php bin/console about

you can get many details about the current project. The first section is about Symfony itself and looks like this:

-------------------- ------------------------------------------- 
 Symfony                                                         
-------------------- ------------------------------------------- 
 Version              4.2.3                                      
 End of maintenance   07/2019                                    
 End of life          01/2020                                    
-------------------- -------------------------------------------

I find the other information besides the version number very useful.

There are also other sections providing details about the (framework) Kernel, PHP, Environment.

Use the following command in your Terminal/Command Prompt:

php bin/console --version

This will give you your Symfony Version.

For Symfony 3.4

Check the constant in this file vendor/symfony/http-kernel/Kernel.php

const VERSION = '3.4.3';

OR 

composer show | grep symfony/http-kernel

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.

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.

we can find the symfony version using Kernel.php file but problem is the Location of Kernal Will changes from version to version (Better Do File Search in you Project Directory)

in symfony 3.0 : my_project\vendor\symfony\symfony\src\Symfony\Component\HttpKernel\Kernel.php

Check from Controller/ PHP File

$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
echo $symfony_version; // this will return version; **o/p:3.0.4-DEV**

From inside your Symfony project, you can get the value in PHP this way:

$symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;

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.

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