How to display similar json array from mysql using php?

Question

PHP

Welcome all!
Such a problem, there is a database with a table of goods, the goods are arranged in a similar way:

Inside the goods, in the last column there is a json array with the available sizes of the goods.
The question is how to correctly display this whole thing in JSON, because when displaying this entry using php, I get a similar picture:
