PHPX-LZ4
========

[](#phpx-lz4)

A quick and dirty AI port of [MiniLZ4](https://github.com/emscripten-core/emscripten/blob/main/third_party/mini-lz4.js) to PHP. MiniLZ4 is a minimal implementation of LZ4 block encoding and decoding, originally based on [node-lz4](https://github.com/pierrec/node-lz4).

Overview
--------

[](#overview)

This library provides a pure PHP implementation of the LZ4 compression algorithm, specifically ported from the JavaScript MiniLZ4 implementation. It maintains compatibility with the original implementation while providing a PHP-native interface.

Features
--------

[](#features)

- Pure PHP implementation
- A quick and dirty AI port of MiniLZ4's
- Block compression and decompression
- Package compression with chunking support
- Verification capabilities
- No external dependencies

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

[](#installation)

You can install the package via composer:

```
composer require syntaxx/lz4
```

Requirements
------------

[](#requirements)

- PHP >= 8.1

Usage
-----

[](#usage)

### Basic Compression/Decompression

[](#basic-compressiondecompression)

```
use Syntaxx\LZ4\LZ4;

// Create an instance
$lz4 = new LZ4();

// Compress data
$compressed = $lz4->compress($data);

// Decompress data
$decompressed = $lz4->decompress($compressed, $originalSize);
```

### Package Compression

[](#package-compression)

```
use Syntaxx\LZ4\LZ4;

// Create an instance
$lz4 = new LZ4();

// Compress data in chunks
$result = $lz4->compressPackage($data, $verify = false);

// Result structure
[
    'data' => string,          // Compressed data
    'cachedOffset' => int,     // Offset for cached chunks
    'cachedIndexes' => array,  // Cache indexes
    'cachedChunks' => array,   // Cached decompressed chunks
    'offsets' => array,        // Chunk offsets
    'sizes' => array,          // Chunk sizes
    'successes' => array       // Compression success flags (1 for success, 0 for failure)
]
```
