I want to create a view that can show all the data from my database.
This is my function. How can I connect this to my twig file?
Can anyone help
What does not works?
If you need a template engine you can use the twig by Symfony Twig initialization in Slim (always into the container).
Anyway i suggest you to see the documentation (container section) for a better approach to the db initialization.
