How do I leverage enums in PHP 8

In PHP 8, enums provide a way to define a set of possible values for a variable. This feature is particularly useful for scenarios where a variable can only take on specific values. Enums help in enhancing code readability and promoting type safety.

enum Status
{
    case Draft;
    case Published;
    case Archived;
}

// Usage
function publishPost(Status $status) {
    switch ($status) {
        case Status::Draft:
            echo "Post is currently in draft.";
            break;
        case Status::Published:
            echo "Post is live!";
            break;
        case Status::Archived:
            echo "Post is archived.";
            break;
    }
}

publishPost(Status::Published);
