A comprehensive PHP library for encoding and decoding **CBOR** (Concise Binary Object Representation) data according to [RFC 8949](https://tools.ietf.org/html/rfc8949).

Features
--------

[](#features)

- ✅ Full support for all CBOR major types (0-7)
- ✅ Extensible tag system with built-in support for common tags
- ✅ Streaming decoder for efficient memory usage
- ✅ Type-safe API with modern PHP features
- ✅ Comprehensive support for indefinite-length objects
- ✅ Built-in normalization to PHP native types

Installation
------------

[](#installation)

```
composer require nullbio/cbor-php
```

**Requirements:**

- PHP 8.5.0
- ext-mbstring 8.5.0
- brick/math 0.14.8

**Optional but recommended:**

- ext-gmp or ext-bcmath for improved performance with large integers
- ext-bcmath for Big Float and Decimal Fraction support

This fork intentionally hard-pins its Composer and platform dependencies. Update them only as an explicit maintenance action.

This project follows [semantic versioning](http://semver.org/) strictly.
