I wrote a blog post about using laravel-enum:


  • Laravel 5.4 or newer
  • PHP 7.1 or newer


Via Composer

composer require bensampo/laravel-enum

If you're using Laravel < 5.5 you'll need to add the service provider to config/app.php


Enum Library

Browse and download from a list of commonly used, community contributed enums.

Enum library →

Basic Usage

Enum Definition

You can use the following Artisan command to generate a new enum class:

php artisan make:enum UserType

Now, you just need to add the possible values your enum can have as constants.


namespace App\Enums;

use BenSampo\Enum\Enum;

final class UserType extends Enum
    const Administrator = 0;
    const Moderator = 1;
    const Subscriber = 2;
    const SuperAdministrator = 3;

That's it! Note that because the enum values are defined as plain constants, you can simple access them like any other class constant.

UserType::Administrator // Has a value of 0


It can be useful to instantiate enums in order to pass them between functions with the benefit of type hinting.

Additionally, it's impossible to instantiate an enum with an invalid value, therefore you can be certain that the passed value is always valid.

For convenience, enums can be instantiated in multiple ways:

// Standard new PHP class, passing the desired enum value as a parameter
$enumInstance = new UserType(UserType::Administrator);

// Static getInstance method, again passing the desired enum value as a parameter
$enumInstance = UserType::getInstance(UserType::Administrator);

// Statically calling the key name as a method, utilizing __callStatic magic
$enumInstance = UserType::Administrator();

// Using the coerce static method to attempt to instantiate an Enum using the given value if it exists.
$enumInstance = UserType::coerce($someValue);

If you want your IDE to autocomplete the static instantiation helpers, you can generate PHPDoc annotations through an artisan command.

By default all Enums in app/Enums will be annotated (you can change the folder by passing a path to --folder)

php artisan enum:annotate

You can annotate a single class by specifying the class name

php artisan enum:annotate "App\Enums\UserType"

Instance Properties

Once you have an enum instance, you can access the key, value and description as properties.

$userType = UserType::getInstance(UserType::SuperAdministrator);

$userType->key; // SuperAdministrator
$userType->value; // 0
$userType->description; // Super Administrator

This is particularly useful if you're passing an enum instance to a blade view.

Instance Casting

Enum instances can be cast to strings as they implement the __toString() magic method.
This also means they can be echoed in blade views, for example.

$userType = UserType::getInstance(UserType::SuperAdministrator);

(string) $userType // '0'

Instance Equality

You can check the equality of an instance against any value by passing it to the is method. For convenience, there is also an isNot method which is the exact reverse of the is method.

$admin = UserType::getInstance(UserType::Administrator);

$admin->is(UserType::Administrator);   // true
$admin->is($admin);                    // true
$admin->is(UserType::Administrator()); // true

$admin->is(UserType::Moderator);       // false
$admin->is(UserType::Moderator());     // false
$admin->is('random-value');            // false

You can also check to see if the instance's value matches against an array of possible values using the in method.

$admin = UserType::getInstance(UserType::Administrator);

$admin->in([UserType::Moderator, UserType::Administrator]);     // true
$admin->in([UserType::Moderator(), UserType::Administrator()]); // true

$admin->in([UserType::Moderator, UserType::Subscriber]);        // false
$admin->in(['random-value']);                                   // false

Type Hinting

One of the benefits of enum instances is that it enables you to use type hinting, as shown below.

function canPerformAction(UserType $userType)
    if ($userType->is(UserType::SuperAdministrator)) {
        return true;

    return false;

$userType1 = UserType::getInstance(UserType::SuperAdministrator);
$userType2 = UserType::getInstance(UserType::Moderator);

canPerformAction($userType1); // Returns true
canPerformAction($userType2); // Returns false

Flagged/Bitwise Enum

Standard enums represent a single value at a time, but flagged or bitwise enums are capable of of representing multiple values simultaneously. This makes them perfect for when you want to express multiple selections of a limited set of options. A good example of this would be user permissions where there are a limited number of possible permissions but a user can have none, some or all of them.

You can create a flagged enum using the following artisan command:

php artisan make:enum UserPermissions --flagged

Defining values

When defining values you must use powers of 2, the easiest way to do this is by using the shift left << operator like so:

final class UserPermissions extends FlaggedEnum
    const ReadComments      = 1 << 0;
    const WriteComments     = 1 << 1;
    const EditComments      = 1 << 2;
    const DeleteComments    = 1 << 3;
    // The next one would be `1 << 4` and so on...

Defining shortcuts

You can use the bitwise or | to set a shortcut value which represents a given set of values.

final class UserPermissions extends FlaggedEnum
    const ReadComments      = 1 << 0;
    const WriteComments     = 1 << 1;
    const EditComments      = 1 << 2;
    const DeleteComments    = 1 << 3;
    // Shortcuts
    const Member = self::ReadComments | self::WriteComments; // Read and write.
    const Moderator = self::Member | self::EditComments; // All the permissions a Member has, plus Edit.
    const Admin = self::Moderator | self::DeleteComments; // All the permissions a Moderator has, plus Delete.

Instantiating a flagged enum

There are couple of ways to instantiate a flagged enum:

// Standard new PHP class, passing the desired enum values as an array of values or array of enum instances
$permissions = new UserPermissions([UserPermissions::ReadComments, UserPermissions::EditComments]);
$permissions = new UserPermissions([UserPermissions::ReadComments(), UserPermissions::EditComments()]);

// Static flags method, again passing the desired enum values as an array of values or array of enum instances
$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::EditComments]);
$permissions = UserPermissions::flags([UserPermissions::ReadComments(), UserPermissions::EditComments()]);

Attribute casting works in the same way as single value enums.

Empty flagged enums

Flagged enums can contain no value at all. Every flagged enum has a pre-defined constant of None which is comparable to 0.

UserPermissions::flags([])->value === UserPermissions::None; // True

Flagged enum methods

In addition to the standard enum methods, there are a suite of helpful methods available on flagged enums.

Note: Anywhere where a static property is passed, you can also pass an enum instance.

setFlags(array $flags): Enum

Set the flags for the enum to the given array of flags.

$permissions = UserPermissions::flags([UserPermissions::ReadComments]);
$permissions->flags([UserPermissions::EditComments, UserPermissions::DeleteComments]); // Flags are now: EditComments, DeleteComments.

addFlag($flag): Enum

Add the given flag to the enum

$permissions = UserPermissions::flags([UserPermissions::ReadComments]);
$permissions->addFlag(UserPermissions::EditComments); // Flags are now: ReadComments, EditComments.

addFlags(array $flags): Enum

Add the given flags to the enum

$permissions = UserPermissions::flags([UserPermissions::ReadComments]);
$permissions->addFlags([UserPermissions::EditComments, UserPermissions::WriteComments]); // Flags are now: ReadComments, EditComments, WriteComments.

removeFlag($flag): Enum

Remove the given flag from the enum

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments]);
$permissions->removeFlag(UserPermissions::ReadComments); // Flags are now: WriteComments.

removeFlags(array $flags): Enum

Remove the given flags from the enum

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments, UserPermissions::EditComments]);
$permissions->removeFlags([UserPermissions::ReadComments, UserPermissions::WriteComments]); // Flags are now: EditComments.

hasFlag($flag): bool

Check if the enum has the specified flag.

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments]);
$permissions->hasFlag(UserPermissions::ReadComments); // True
$permissions->hasFlag(UserPermissions::EditComments); // False

hasFlags(array $flags): bool

Check if the enum has all of the specified flags.

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments]);
$permissions->hasFlags([UserPermissions::ReadComments, UserPermissions::WriteComments]); // True
$permissions->hasFlags([UserPermissions::ReadComments, UserPermissions::EditComments]); // False

notHasFlag($flag): bool

Check if the enum does not have the specified flag.

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments]);
$permissions->notHasFlag(UserPermissions::EditComments); // True
$permissions->notHasFlag(UserPermissions::ReadComments); // False

notHasFlags(array $flags): bool

Check if the enum doesn't have any of the specified flags.

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments]);
$permissions->notHasFlags([UserPermissions::ReadComments, UserPermissions::EditComments]); // True
$permissions->notHasFlags([UserPermissions::ReadComments, UserPermissions::WriteComments]); // False

getFlags(): Enum[]

Return the flags as an array of instances.

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments]);
$permissions->getFlags(); // [UserPermissions::ReadComments(), UserPermissions::WriteComments()];

hasMultipleFlags(): bool

Check if there are multiple flags set on the enum.

$permissions = UserPermissions::flags([UserPermissions::ReadComments, UserPermissions::WriteComments]);
$permissions->hasMultipleFlags(); // True;
$permissions->removeFlag(UserPermissions::ReadComments)->hasMultipleFlags(); // False

getBitmask(): int

Get the bitmask for the enum.

UserPermissions::Member()->getBitmask(); // 11;
UserPermissions::Moderator()->getBitmask(); // 111;
UserPermissions::Admin()->getBitmask(); // 1111;
UserPermissions::DeleteComments()->getBitmask(); // 1000;

Attribute Casting

You may cast model attributes to enums using the CastsEnums trait. This will cast the attribute to an enum instance when getting and back to the enum value when setting.

Similar to how standard attribute casting works, you simply define which attributes you want to cast to which enum as an array on the model.

use BenSampo\Enum\Traits\CastsEnums;
use BenSampo\Enum\Tests\Enums\UserType;
use Illuminate\Database\Eloquent\Model;

class Example extends Model
    use CastsEnums;

    protected $enumCasts = [
        // 'attribute_name' => Enum::class
        'user_type' => UserType::class,

     * Existing casts are processed before $enumCasts which can be useful if you're 
     * taking input from forms and your enum values are integers.
    protected $casts = [
        'user_type' => 'int',

Now, when you access the user_type attribute of your Example model, the underlying value will be returned as a UserType enum.

$example = Example::first();
$example->user_type // Instance of UserType

Review the methods and properties available on enum instances to get the most out of attribute casting.

You can set the value by either passing the enum value or another enum instance.

$example = Example::first();

// Set using enum value
$example->user_type = UserType::Moderator;

// Set using enum instance
$example->user_type = UserType::Moderator();

Model Annotation

The package can automatically generate DocBlocks for your Model classes to provide type hinting & completion in your IDE.

By default all Model classes in the root of app will be annotated (you can change the folder by passing a path to --folder)

php artisan enum:annotate-model


Array Validation

You may validate that an enum value passed to a controller is a valid value for a given enum by using the EnumValue rule.

public function store(Request $request)
    $this->validate($request, [
        'user_type' => ['required', new EnumValue(UserType::class)],

By default, type checking is set to strict, but you can bypass this by passing false to the optional second parameter of the EnumValue class.

new EnumValue(UserType::class, false) // Turn off strict type checking.

You can also validate on keys using the EnumKey rule. This is useful if you're taking the enum key as a URL parameter for sorting or filtering for example.

public function store(Request $request)
    $this->validate($request, [
        'user_type' => ['required', new EnumKey(UserType::class)],

Of course, both of these work on form request classes too.

Make sure to include BenSampo\Enum\Rules\EnumValue and/or BenSampo\Enum\Rules\EnumKey and your enum class in the usings.

Pipe Validation

You can also use the 'pipe' syntax for both the EnumKey and EnumValue rules by using enum_value and/or enum_key respectively.


'user_type' => 'required|enum_value:' . UserType::class,
'user_type' => 'required|enum_key:' . UserType::class,


You can translate the strings returned by the getDescription method using Laravel's built in localization features.

Add a new enums.php keys file for each of your supported languages. In this example there is one for English and one for Spanish.

// resources/lang/en/enums.php

use App\Enums\UserType;

return [

    UserType::class => [
        UserType::Administrator => 'Administrator',
        UserType::SuperAdministrator => 'Super administrator',

// resources/lang/es/enums.php

use App\Enums\UserType;

return [

    UserType::class => [
        UserType::Administrator => 'Administrador',
        UserType::SuperAdministrator => 'Súper administrador',


Now, you just need to make sure that your enum implements the LocalizedEnum interface as demonstrated below:

use BenSampo\Enum\Enum;
use BenSampo\Enum\Contracts\LocalizedEnum;

final class UserType extends Enum implements LocalizedEnum
    // ...

The getDescription method will now look for the value in your localization files. If a value doesn't exist for a given key, the default description is returned instead.

Overriding the getDescription method

If you'd like to return a custom value from the getDescription method, you may do so by overriding the method on your enum:

public static function getDescription($value): string
    if ($value === self::SuperAdministrator) {
        return 'Super admin';

    return parent::getDescription($value);

Calling UserType::getDescription(3); now returns Super admin instead of Super administator.

Extending the Enum Base Class

The Enum base class implements the Laravel Macroable trait, meaning it's easy to extend it with your own functions. If you have a function that you often add to each of your enums, you can use a macro.

Let's say we want to be able to get a flipped version of the enum toArray method, we can do this using:

Enum::macro('toFlippedArray', function() {
    return array_flip(self::toArray());

Now, on each of my enums, I can call it using UserType::toFlippedArray().

It's best to register the macro inside of a service providers' boot method.

PHPStan integration

If you are using PHPStan for static analysis, you can enable the extension for proper recognition of the magic instantiation methods.

Add the following to your projects phpstan.neon includes:

- vendor/bensampo/laravel-enum/extension.neon
