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

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**
