How to properly organize the storage of the id list in COOKIE?

Question

PHP

Good afternoon!
Please tell me how to properly organize cookies in one variable, storing a list of apartment id for favorites?

Answer 1

Serialize to JSON. JSON.stringify(object);- will turn your data structure into a string that can be stored in cookies. And then, having loaded back a line, through JSON.parse(string);you will receive back the data.
