Implementation of multilingualism?

Question

PHP

Now I have all the static records for filling the template are stored in * .json
But I thought, I have 3 languages ​​​​at the moment (mb will be needed and much more).
Make a template for each language and call them..
In order not to process the entire template, etc.
How do you look at it?
You also need js to fill some blocks with text, also by language, how to implement this?
Not ajax?

Answer 1

The idea to store everything necessary for the language (all output / displayed text) in json is quite acceptable.
If you use php, you can also through the database.
