README

A comprehensive PHP library providing type-safe enum classes for commonly used domains. Stop reinventing the wheel - use battle-tested, well-documented enums across all your PHP projects.

Why Use This Library?

Framework Agnostic - Works with Laravel, Symfony, Slim, CodeIgniter, or any PHP 8.1+ application
Type Safety - Leverage PHP 8.1 native enums for compile-time type checking
Consistent API - All enums follow the same patterns with fullName(), toArray(), and domain-specific helper methods
Internationalization Ready - Brazilian Portuguese translations included via fullNamePtBr() methods
Well Tested - 247 tests with 1,669 assertions ensuring reliability
Zero Dependencies - No external packages required

Requirements

PHP 8.1 or higher

Installation

composer require dev-toolbelt/enums

Available Enums

The library organizes enums into logical namespaces:

Namespace	Enums	Description
`Security`	Algorithm	JWT/cryptographic algorithms (HS256, RS256, ES256, etc.)
`Brazil`	BrazilianState, BrazilianDocumentType, BrazilianBankCode	Brazilian-specific data
`Http`	HttpMethod, HttpStatusCode, MimeType	HTTP protocol enums
`Locale`	Country, Currency, Language, Timezone	Internationalization
`Calendar`	Month, DayOfWeek	Date and time
`Personal`	Gender, ContactType	Personal information
`Measurement`	Temperature	Units of measurement

Building Select Dropdowns

All enums provide toArray() methods perfect for HTML select elements:

use DevToolbelt\Enums\Brazil\BrazilianState;

// For Blade/Twig templates
$states = BrazilianState::toArrayWithFullNames();

// Result: ['AC' => 'Acre', 'AL' => 'Alagoas', 'AM' => 'Amazonas', ...]

<select name="state">
    @foreach($states as $uf => $name)
        <option value="{{ $uf }}">{{ $name }}</option>
    @endforeach
</select>

Framework Integration

Laravel

// In a Form Request
use DevToolbelt\Enums\Brazil\BrazilianState;
use Illuminate\Validation\Rule;

public function rules(): array
{
    return [
        'state' => ['required', Rule::enum(BrazilianState::class)],
    ];
}

// In an Eloquent Model
use DevToolbelt\Enums\Http\HttpStatusCode;

protected $casts = [
    'status' => HttpStatusCode::class,
];

Symfony

// In a Doctrine Entity
use DevToolbelt\Enums\Locale\Currency;
use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity]
class Product
{
    #[ORM\Column(type: 'string', enumType: Currency::class)]
    private Currency $currency;
}
