Accessing Symfony global and server variables in Twig views through the “app” variable

In Symfony, you don’t always have to actually pass values from your controllers to your Twig views.  Twig can actually pull global and server values directly through the super global “app” variable.  Most frequently, you can access these corresponding objects like Kernel, Request, Security and Session variables like so:

{{app.kernel.cachedir}}
{{app.kernel.logdir}}
{{app.kernel.rootdir}}
 
{{app.request.basepath}}
{{app.request.baseurl}}
{{app.request.uri}}

{{app.security.token.user}}

{{app.session.locale}}
