...For text, this means wrapping each with a function capable of translating the text (or “message”) into the language of the user. Enable and configure Symfony’s translation service. Abstract strings (i.e. “messages”) by wrapping them in calls to the Translator (”Basic Translation”). Create translation resources/files for each supported locale that translate each message in the application. Determine, set and manage the user’s locale for the request and optionally on the user’s entire session. The locale used in translations is the one stored on the request. This is typically set via a _locale attribute on your routes.
