Simple Data ObjectsTyped PHP data objects, compiled for speed

Up to 60× faster than the most popular alternative, with the same attribute-driven classes. Hydration, validation, casting and serialization — no boilerplate, no runtime reflection. PHP 8.4+, plain PHP or Laravel 12–13.

Turn input into objects

Arrays, JSON, requests, Eloquent models — one from() call gives you a typed, immutable object.

Hydration

Validate and report errors

Laravel validation rules next to the property, or inferred from its type. Throw, or collect every error at once.

Validation

Convert types

Dates, enums, money, JSON, encrypted values — built-in casts, or your own in a dozen lines.

Built-in casts

Send data back out

toArray() and toJson() with renamed keys, hidden fields, computed values and per-context visibility.

Serialization

Import large files

Stream a CSV or a 50 MB XML feed one record at a time. Memory stays flat however big the file is.

Streaming XML

Use it with Laravel

Requests, controller injection, Eloquent casts, Livewire and pagination — each one opt-in.

Laravel setup

The whole idea in one screen

A data object is a class with typed constructor properties. Attributes describe anything that isn't obvious from the types.

Define it once

php

use StdOut\SimpleDataObjects\BaseData;
use StdOut\SimpleDataObjects\Attributes\{Cast, Rules};
use StdOut\SimpleDataObjects\Casts\DateTimeCast;

class UserData extends BaseData
{
    public function __construct(
        #[Rules(['required', 'string', 'max:120'])]
        public readonly string $name,

        #[Rules(['required', 'email'])]
        public readonly string $email,

        #[Cast(new DateTimeCast('Y-m-d'))]
        public readonly ?DateTime $birthday = null,
    ) {}
}

Use it everywhere

php

// from an array, JSON, a request, a model…
$user = UserData::from($request->all());

// …validated first, if you want
$user = UserData::fromValidated($payload);

$user->name;                  // typed, autocompleted
$user->birthday?->format('d M');

$user->toArray();             // back to plain data
$user->with(name: 'Alice');   // a modified copy

UserData::collection($rows);  // typed collection

Why it is fast

Speed is the reason this library exists, not a side effect. Three decisions account for it.
