Symfony 5: The Fast Track is the best book to learn
modern Symfony development, from zero to production. +300 pages showcasing Symfony with
Docker, APIs, queues & async tasks, Webpack, SPAs, etc.
The Dialog Helper was deprecated in Symfony 2.5 and removed in
Symfony 3.0. You should now use the
Question Helper instead,
which is simpler to use.
