How to declare global constants in Zend Framework 3?

Question

How to declare constants to access in modules, controllers, services and others? Zend Framework 3

Answer 1

If you mean constants literally, just put them in class and you can use them anywhere, for example:

namespace Logic\User;

class Type
{
    const ADMIN = 1;
    const EDITOR = 2;
    const READER = 3;
}

Use:

$userType = \Logic\User\Type::ADMIN;

If you understand constants as global, reusable values, try to put them in ZF3 configuration .
