README

A PHP library that provides schema-based Avro data serialization and deserialization.

Key features:

• Support for logical types
• Developer-friendly error messages for schema validation
• Schema resolution including promotion of primitive types
• Serialization of objects through getters or public properties
• Default values for record fields
• Configurable block count and block size for array and map encoding

Installation

To install auxmoney/avro-php, you can use Composer:

composer require auxmoney/avro-php

Usage

Encoding/Decoding Data

Try out the example scripts:

php examples/encoding.php
php examples/decoding.php
php examples/logical-type.php

Logical Types

It is possible to configure logical types in a few different ways:

Using Default Logical Types

There are built-in implementations for all logical types described in the AVRO specification, except for timestamp-nanos and local-timestamp-nanos, because PHP's DateTime doesn't have nanosecond precision.

To use the default logical types, simply create an AvroFactory without any options:

$avroFactory = AvroFactory::create();

Overriding Logical Types

You can override default logical types or add custom ones by providing factory implementations:

$defaultLogicalTypeFactories = AvroFactory::getDefaultLogicalTypeFactories();
$defaultLogicalTypeFactories['custom'] = new MyCustomLogicalTypeFactory();
$options = new Options(logicalTypeFactories: $defaultLogicalTypeFactories);
$avroFactory = AvroFactory::create($options);

Disabling Logical Types

To disable all logical type processing and treat them as their underlying primitive types:

$options = new Options(logicalTypeFactories: []);
$avroFactory = AvroFactory::create($options);

Value Objects for Logical Types

Some logical types work with their respective value objects to provide type safety and better representation of the data:

• decimal: Auxmoney\Avro\ValueObject\Decimal
• duration: Auxmoney\Avro\ValueObject\Duration
• time-millis: Auxmoney\Avro\ValueObject\TimeOfDay
• time-micros: Auxmoney\Avro\ValueObject\TimeOfDay
• uuid: Auxmoney\Avro\ValueObject\Uuid

The local-timestamp-* and timestamp-* types are serialized from/deserialized to DateTimeInterface.

Development Setup

This project uses VS Code Dev Containers for development. This ensures a consistent development environment across all contributors.

Using VS Code Dev Container (Recommended)

1. Install the Dev Containers extension in VS Code
2. Open the project in VS Code
3. When prompted, click "Reopen in Container" or use Ctrl+Shift+P → "Dev Containers: Reopen in Container"

The container includes:

• PHP 8.3 with Xdebug
• Composer for dependency management
• PHPUnit for testing
• Node.js for test generation tools
• Git and GitHub CLI

Manual Docker Usage

You can also use the containers manually:

# Using the convenience script (recommended)
./docker-dev run --rm dev
./docker-dev run --rm dev vendor/bin/phpunit
./docker-dev run --rm test-generator

# Or using docker compose directly
docker compose -f .devcontainer/docker-compose.yaml run --rm dev
docker compose -f .devcontainer/docker-compose.yaml run --rm dev vendor/bin/phpunit
docker compose -f .devcontainer/docker-compose.yaml run --rm test-generator

For more details, see .devcontainer/README.md.
