> **Note:** This is a PHP implementation based on the original TOON format specification and reference implementations from [toon-format/toon](https://github.com/toon-format/toon)

PHP implementation of **Token-Oriented Object Notation (TOON)**, a compact, human-readable serialization format designed for passing structured data to Large Language Models with significantly reduced token usage.

TOON is intended for LLM input, not output. It's particularly efficient for **uniform arrays of objects** – multiple fields per row, same structure across items.

Features
--------

[](#features)

- 💸 **Token-efficient:** typically 30–60% fewer tokens than JSON
- 🤿 **LLM-friendly guardrails:** explicit lengths and fields enable validation
- 🍱 **Minimal syntax:** removes redundant punctuation (braces, brackets, most quotes)
- 📐 **Indentation-based structure:** like YAML, uses whitespace instead of braces
- 🧺 **Tabular arrays:** declare keys once, stream data as rows
- ✅ **Full compatibility:** Implements the [TOON v1.3 specification](https://github.com/toon-format/spec)

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