README

This library provides a collection of native enum utilities (traits) which you almost always need in every PHP project.

Arrayable
Assertable
Comparable
NameListable
ValueListable
WithUtilities

Installation

You can install the package via composer:

composer require dive-be/php-enum-utils

Usage

Assume the following string backed enum:

enum Role: string
{
    use \Dive\Enum\Arrayable;
    use \Dive\Enum\Assertable;
    use \Dive\Enum\Comparable;
    use \Dive\Enum\NameListable;
    use \Dive\Enum\ValueListable;

    case Administrator = 'admin';
    case Auditor = 'audit';
    case Moderator = 'mod';
}

Arrayable (backed enums only)

Allows you to retrieve a key-value pair of names and values:

Role::toArray(); // ['Administrator' => 'admin', 'Auditor' => 'audit', 'Moderator' => 'mod']

Assertable

This relies on the enum names being in PascalCase, which follows Larry Garfield's RFC.

Allows you to make assertions on enum instances using predicate functions:

$role = Role::Moderator;

$role->isAuditor(); // false
$role->isModerator(); // true

Comparable

Allows you to compare enums. Mostly useful when providing backed values:

$role = Role::Administrator;

$role->equals('admin'); // true
$role->equals(Role::Administrator); // true
$role->equals('mod'); // false
$role->equals(Role::Moderator); // false

$role->equalsAny(['admin', 'mod', 'audit']); // true
$role->equalsAny([Role::Administrator, Role::Auditor]); // true
$role->equalsAny([Role::Moderator, 'audit']); // false

NameListable

Allows you to retrieve a list of the enum names:

Role::toNames(); // ['Administrator', 'Auditor', 'Moderator']

ValueListable (backed enums only)

Allows you to retrieve a list of the enum values:

Role::toValues(); // ['admin', 'audit', 'mod']

WithUtilities (backed enums only)

Aggregator trait for all of the aforementioned utilities.
