PHP Typed Values

Typed value objects for PHP. Build precise, immutable, and validated data for DTOs, Value Objects, and Entities.

Install

• Use V3 for PHP 8.4:

composer require georgii-web/php-typed-values:^3

• Use V2 for PHP >=8.2 & <8.4:

composer require georgii-web/php-typed-values:^2

• Use V1 for PHP 7.4:

composer require georgii-web/php-typed-values:^1

Why

• Strong typing for scalars with runtime validation
• Immutable and self‑documenting values
• Safer constructors for your DTOs/VOs/Entities
• Great fit for static analysis
• Safe type conversion, no silent errors

Quick start

Use existing typed values

use PhpTypedValues\Integer\IntegerPositive;

$id = IntegerPositive::fromString('123');

Instead of spreading validation across an application

$id = (int) '123';
if ($id <= 0) {
    throw new InvalidArgumentException('Invalid ID');
}

Create an alias (in your domain)

use PhpTypedValues\Integer\IntegerPositive;

readonly class Id extends IntegerPositive {}

Id::fromInt(123);

Create composite objects

final readonly class Profile
{
    public function __construct(
        private IntegerPositive $id,
        private StringUsername $username,
        private FloatPositive|Undefined $rating,
    ) {}
}

Undefined

Prefer using the Undefined type over null to maintain consistency and improve type safety within the codebase.

Other usage examples docs/USAGE.md

Key features

• Idempotent conversion on fromString() > toString(): "1" > 1 > "1"
• Static analysis friendly
• Strict types
• Validation on construction; no invalid state
• Immutable, readonly objects
• No external runtime dependencies
• Easy to extend with your own types and composites
• Heavily tested

Performance note

• Objects vs Scalars:
  • ~2.3× slower for large arrays of objects
  • ~1.5× higher memory usage
• Use value objects for domain boundaries, validation, and clarity
• Use raw scalars in hot loops or large data processing paths
