How to check your version
Which Symfony is this site on?
In the app
$ php bin/console --version
Symfony 7.4.21 (env: prod, debug: false)
In the lock file
$ composer show symfony/http-kernel | grep versions
versions : * v7.4.21
# Laravel and Craft use Symfony components too; their version follows the framework
Know before support ends.
Porro reads the PHP, framework and database version from every site and tells you 90 days before support runs out.
