What type of field to specify in Mysql for data separated by commas?

Question

MySQL

You need to add an 'extra' column to the table in order to enter individual parameters there. I assume the parameters are separated by commas, and when receiving from the database, simply separate them by commas and enter them into an array.
There was a question: what type of a field to use? The length and number of parameters cannot be predetermined. Varchar will probably be small or not?
Criteria: the maximum required field type so that it does not take up more space than necessary.

Answer 1

It's time to use JSON instead of "parameters separated by commas, and when getting from the database, just separate them by commas and put them in an array"...

Answer 2

Use JSON, it is supported by both MySQL and Laravel
