Installation

Requires PHP 8, and Laravel 9 or 10.

composer require bensampo/laravel-enum

Migrate to Native PHP Enums

PHP 8.1 supports enums natively. You can migrate your usages of BenSampo\Enum\Enum to native PHP enums using the following steps.

Make sure you meet the following requirements:

  • PHP 8.1 or higher
  • Laravel 10 or higher
  • Rector 0.17 or higher, your rector.php includes all relevant files
  • Latest version of this library

Depending on the size of your project, you may choose to migrate all enums at once, or migrate just a couple or one enum at a time.

  • Convert all enums at once: php artisan enum:to-native

  • Pass the fully qualified class name of an enum to limit the conversion: php artisan enum:to-native "App\Enums\UserType"

    This is necessary if any enums are used during the bootstrap phase of Laravel, the conversion of their usages interferes with Larastan and prevents a second run of Rector from working.

Review and validate the code changes for missed edge cases:

  • See Unimplemented
  • Enum::coerce(): If only values were passed, you can replace it with tryFrom(). If keys or instances could also be passed, you might need additional logic to cover this.
  • Enum::$description and Enum::getDescription(): Implement an alternative.
  • try/catch-blocks that handle BenSampo\Enum\Exceptions\InvalidEnumKeyException or BenSampo\Enum\Exceptions\InvalidEnumMemberException. Either catch the ValueError thrown by native enums, or switch to using tryFrom() and handle null.

Once all enums are converted, you can remove your dependency on this 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.

<?php declare(strict_types=1);

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 simply access them like any other class constant.

UserType::Administrator // Has a value of 0

Instantiation

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);

// Same as the constructor, instantiate by value
$enumInstance = UserType::fromValue(UserType::Administrator);

// Use an enum key instead of its value
$enumInstance = UserType::fromKey('Administrator');

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

// Attempt to instantiate a new Enum using the given key or value. Returns null if the Enum cannot be instantiated.
$enumInstance = UserType::coerce($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::fromValue(UserType::SuperAdministrator);

$userType->key; // SuperAdministrator
$userType->value; // 3
$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::fromValue(UserType::SuperAdministrator);

(string) $userType // '3'

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::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, and use notIn to check if instance value is not in an array of values. Iterables can also be checked against.

$admin = 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

$admin->notIn([UserType::Moderator, UserType::Administrator]);     // false
$admin->notIn([UserType::Moderator(), UserType::Administrator()]); // false

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

The instantiated enums are not singletons, rather a new object is created every time. Thus, strict comparison === of different enum instances will always return false, no matter the value. In contrast, loose comparison == will depend on the value.

$admin = UserType::Administrator();

$admin === UserType::Administrator();                    // false
UserType::Administrator() === UserType::Administrator(); // false
$admin === UserType::Moderator();                        // false

$admin === $admin;                                       // true

$admin == UserType::Administrator(); // true
$admin == UserType::Administrator;   // true

$admin == UserType::Moderator();     // false
$admin == UserType::Moderator;       // 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::fromValue(UserType::SuperAdministrator);
$userType2 = UserType::fromValue(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.

addAllFlags(): Enum

Add all flags to the enum

$permissions = UserPermissions::flags([UserPermissions::ReadComments]);
$permissions->addAllFlags(); // Enum now has all flags

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.

removeAllFlags(): Enum

Remove all flags from the enum

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

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;

Flagged enums in Eloquent queries

To use flagged enums directly in your Eloquent queries, you may use the QueriesFlaggedEnums trait on your model which provides you with the following methods:

hasFlag($column, $flag): Builder

User::hasFlag('permissions', UserPermissions::DeleteComments())->get();

notHasFlag($column, $flag): Builder

User::notHasFlag('permissions', UserPermissions::DeleteComments())->get();

hasAllFlags($column, $flags): Builder

User::hasAllFlags('permissions', [UserPermissions::EditComment(), UserPermissions::ReadComment()])->get();

hasAnyFlags($column, $flags): Builder

User::hasAnyFlags('permissions', [UserPermissions::DeleteComments(), UserPermissions::EditComments()])->get();

Attribute Casting

You may cast model attributes to enums using Laravel's built in custom casting. This will cast the attribute to an enum instance when getting and back to the enum value when setting. Since Enum::class implements the Castable contract, you just need to specify the classname of the enum:

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

class Example extends Model
{
    protected $casts = [
        'random_flag' => 'boolean',     // Example standard laravel cast
        'user_type' => UserType::class, // Example enum cast
    ];
}

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();

Customising $model->toArray() behaviour

When using toArray (or returning model/models from your controller as a response) Laravel will call the toArray method on the enum instance.

By default, this will return only the value in its native type. You may want to also have access to the other properties (key, description), for example to return to javascript app.

To customise this behaviour, you can override the toArray method on the enum instance.

// Example Enum
final class UserType extends Enum
{
    const ADMINISTRATOR = 0;
    const MODERATOR = 1;
}

$instance = UserType::Moderator();

// Default
public function toArray()
{
    return $this->value;
}
// Returns int(1)

// Return all properties
public function toArray()
{
    return $this;
}
// Returns an array of all the properties
// array(3) {
//  ["value"]=>
//  int(1)"
//  ["key"]=>
//  string(9) "MODERATOR"
//  ["description"]=>
//  string(9) "Moderator"
// }

Casting underlying native types

Many databases return everything as strings (for example, an integer may be returned as the string '1'). To reduce friction for users of the library, we use type coercion to figure out the intended value. If you'd prefer to control this, you can override the parseDatabase static method on your enum class:

final class UserType extends Enum
{
    const Administrator = 0;
    const Moderator = 1;

    public static function parseDatabase($value)
    {
        return (int) $value;
    }
}

Returning null from the parseDatabase method will cause the attribute on the model to also be null. This can be useful if your database stores inconsistent blank values such as empty strings instead of NULL.

Model Annotation

If you're casting attributes on your model to enums, the laravel-ide-helper package can be used to automatically generate property docblocks for you.

Migrations

Because enums enforce consistency at the code level it's not necessary to do so again at the database level, therefore the recommended type for database columns is string or int depending on your enum values. This means you can add/remove enum values in your code without worrying about your database layer.

use App\Enums\UserType;
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void
    {
        Schema::table('users', function (Blueprint $table): void {
            $table->bigIncrements('id');
            $table->timestamps();
            $table->string('type')
                ->default(UserType::Moderator);
        });
    }
}

Using enum column type

Alternatively you may use Enum classes in your migrations to define enum columns. The enum values must be defined as strings.

use App\Enums\UserType;
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void
    {
        Schema::table('users', function (Blueprint $table): void {
            $table->bigIncrements('id');
            $table->timestamps();
            $table->enum('type', UserType::getValues())
                ->default(UserType::Moderator);
        });
    }
}

Validation

Array Validation

Enum value

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

use BenSampo\Enum\Rules\EnumValue;

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.

Enum key

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.

use BenSampo\Enum\Rules\EnumKey;

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

Enum instance

Additionally you can validate that a parameter is an instance of a given enum.

use BenSampo\Enum\Rules\Enum;

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

Pipe Validation

You can also use the 'pipe' syntax for rules.

enum_value:enum_class,[strict]
enum_key:enum_class
enum:enum_class

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

Localization

Validation messages

Run the following command to publish the language files to your lang folder.

php artisan vendor:publish --provider="BenSampo\Enum\EnumServiceProvider" --tag="translations"

Enum descriptions

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.

// lang/en/enums.php
<?php declare(strict_types=1);

use App\Enums\UserType;

return [

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

];

// lang/es/enums.php
<?php declare(strict_types=1);

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.

Customizing descriptions

Customizing class description

If you'd like to return a custom description for your enum class, add a Description attribute to your Enum class:

use BenSampo\Enum\Enum;
use BenSampo\Enum\Attributes\Description;

#[Description('List of available User types')]
final class UserType extends Enum
{
    ...
}

Calling UserType::getClassDescription() now returns List of available User types instead of User type.

You may also override the getClassDescription method on the base Enum class if you wish to have more control of the description.

Customizing value descriptions

If you'd like to return a custom description for your enum values, add a Description attribute to your Enum constants:

use BenSampo\Enum\Enum;
use BenSampo\Enum\Attributes\Description;

final class UserType extends Enum
{
    const Administrator = 'Administrator';

    #[Description('Super admin')]
    const SuperAdministrator = 'SuperAdministrator';
}

Calling UserType::SuperAdministrator()->description now returns Super admin instead of Super administrator.

You may also override the getDescription method on the base Enum class if you wish to have more control of the description.

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 asArray method, we can do this using:

Enum::macro('asFlippedArray', function() {
    return array_flip(self::asArray());
});

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

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

Laravel Nova Integration

Use the nova-enum-field package by Simple Squid to easily create fields for your Enums in Nova. See their readme for usage.

PHPStan Integration

If you are using PHPStan for static analysis, enable the extension for:

  • proper recognition of the magic instantiation methods
  • detection of duplicate enum values

Use PHPStan Extension Installer or add the following to your projects phpstan.neon includes:
