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    lt  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    lt p gt  Built With Symfony    symfony version      Version MIT License lt  p gt    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

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
