anik/php-enum-enhancements provides a few methods to retrieve keys, values or kv pair on PHP Enums.

To install the package, run

composer require anik/php-enum-enhancements

Use the Anik\PhpEnumEnhancements\Enhancement trait in any of your Enum, and you'll have access to the following method.

# [\UnitEnum | \BackedEnum ]::case->getName(/* null or callable */)
# \BackedEnum::case->getValue(/* null or callable */)
# [\UnitEnum | \BackedEnum ]::names(/* null or callable */)
# \BackedEnum::values(/* null or callable */)
# \BackedEnum::kvPair(
        /* nameCallback: null or callable, */ 
        /* valueCallback: null or callable, */ 
        /* valueAsKey: bool */
#   )

For the enum below,

enum PostStatus: string {
    use \Anik\PhpEnumEnhancements\Enhancement;
    
    case DRAFT = 'draft';
    case UNDER_REVIEW = 'under_review';
    case PUBLISHED = 'published';
}

• PostStatus::DRAFT->getName() will return "DRAFT" .

• PostStatus::DRAFT->getName('strtolower') will return "draft" .

• PostStatus::DRAFT->getValue() will return "draft" .

• PostStatus::DRAFT->getValue('ucfirst') will return "Draft" .

• PostStatus::names() will return [ "DRAFT", "UNDER_REVIEW", "PUBLISHED", ] .

• PostStatus::names('strtolower') will return [ "draft", "under_review", "published", ] .

• PostStatus::values() will return [ "draft", "under_review", "published", ] .

• PostStatus::values('ucfirst') will return [ "Draft", "Under_review", "Published", ] .

• PostStatus::kvPair() will return [ "draft" => "DRAFT", "under_review" => "UNDER_REVIEW", "published" => "PUBLISHED", ] .

• PostStatus::kvPair(nameCallback: 'strtolower') will return [ "draft" => "draft", "under_review" => "under_review", "published" => "published", ] .

• PostStatus::kvPair(valueCallback: 'ucfirst') will return [ "Draft" => "DRAFT", "Under_review" => "UNDER_REVIEW", "Published" => "PUBLISHED", ] .

• PostStatus::kvPair(valueAsKey: false) will return [ "DRAFT" => "draft", "UNDER_REVIEW" => "under_review", "PUBLISHED" => "published", ] in ['NAME_OF_ENUM' => 'VALUE_OF_ENUM'] format.
