Enumerations:

Create Enum also known as Enumeration.

Before Enum we are creating Enum like that:

class Status
{
    const DRAFT = 'draft';
    const PUBLISHED = 'published';
    const ARCHIVED = 'archived';
}
function acceptStatus(string $status) {...}

Now we are creating like that

Use enum instead of a set of constants and get validation out of the box.

Syntax:

enum Status

{
    case Draft;
    case Published;
    case Archived;
}
function acceptStatus(Status $status) {...}

you can access it like that Status::Draft;
