Check something like Permission, Roles, etc.. by using bitwise operations.

Example Usage

require 'vendor/autoload.php';

use Buki\BitPermission\Binary;
use Buki\BitPermission\Sequent;

// FOR ROLE MANAGEMENT
class Role
{
    const GUEST = 0;
    const USER = 1;
    const EDITOR = 2;
    const AUTHOR = 3;
    const ADMIN = 4;
    const ROOT = 5;
}

$role = new Sequent;
$role->add([Role::USER, Role::AUTHOR]);

$role->has(ROLE::USER); // true
$role->has(ROLE::AUTHOR); // true
$role->has(ROLE::EDITOR); // false

// FOR PERMISSION MANAGEMENT
class Permission
{
    // Each permission is represented by a single bit.
    const NONE = 0x0000; // 0000
    const READ = 0x0001; // 0001
    const WRITE = 0x0002; // 0010
    const UPDATE = 0x0004; // 0100
    const DELETE = 0x0008; // 1000
    const SUPER = 0x000f; // 1111
}

$permission = new Binary;
$permission->add([Permission::READ, Permission::WRITE]);

$permission->has(Permission::READ); // true
$permission->has(Permission::DELETE); // false

Also, you can use Enum for your permission or role definitions. (or another things)
Please check out the tests to review more use cases.
