What advantages does PHP offer when choosing between using enumerations and creating custom classes with implemented methods?

In PHP, enumerations (enums), introduced in recent versions, provide a convenient way to define a set of fixed values with type safety and code readability.

Advantages of enums over classes with methods:

• Clarity and simplicity: enum explicitly restricts the set of allowable values.
• Type safety: the compiler and IDE can check the correctness of value usage.
• Less code: no need to create separate constants and methods for validation.

However, custom classes with methods offer more flexibility, such as implementing complex logic, storing state, or using inheritance.

Example of enum in PHP:

enum Status: string {
    case Active = 'active';
    case Inactive = 'inactive';
    case Pending = 'pending';
}

function checkStatus(Status $status) {
    if ($status === Status::Active) {
        echo "Active";
    }
}

The choice depends on the task: if a fixed set of values is needed — enum is preferable; if complex behavior is required — class.
