    UnitEnum 接口

    (PHP 8 >= 8.1.0)

    简介

    引擎会自动应用 UnitEnum 接口到所有枚举。 用户自定义类不能实现该接口。 由于引擎已提供枚举的默认实现，因此不能重载它的接口。 主要将它用于类型检测。

    接口摘要

    interface UnitEnum {
    /* 方法 */
    public static cases(): array
    }

    When looping through cases, you will need to access the values as an object and not an array, like this:

    <?php

    enum BlogStatus     : string {
        case     Published = "is_published";
        case     Draft = "is_draft";
        case     Scheduled = "is_scheduled";
    }

    foreach (    BlogStatus::case() as $datum){
        echo     $datum->name . '<br />'; // Published || Draft || Scheduled
            echo $datum->value . '<br />'; // is_publised || is_draft || is_scheduled
    }

    ?>
