PHP中一个用户的各种角色

Question

I have an idea of doing a back office for my website. The problem is that, when I introduce a user who has, for example, two roles, I want the user to choose the role to work with, but I can't figure out how to do that. I've tried so different things such as putting the two roles separate with commas in MySQL and separating them in PHP but it didn't work.

Answer 1

let say you have a user table, and a user can have multiple role.

you can create a master table for role ( let say roles )

you can have a field on user table say user_roles -> it can have values like 1,2,4

note:- there should not be gaps between the numbers / comma

on the front-end you can take a mutiselect / tags UI element to input role for the user.

to fetch the role of a user at server side - you can use explode() + in_array() to check the role if exists

comma separated example
