MiniSnowflake
=============

[![License](https://camo.githubusercontent.com/7013272bd27ece47364536a221edb554cd69683b68a46fc0ee96881174c4214c/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f6c6963656e73652d4d49542d626c75652e737667)](LICENSE)

A lightweight, case-insensitive, 9-character unique ID generator based on a mini Snowflake algorithm, written in PHP.

Built for high-performance systems needing short, collision-resistant IDs without long UUIDs.

---

Features
--------

[](#features)

- ✅ 9-character alphanumeric IDs
- ✅ Based on a customizable epoch (like Twitter Snowflake)
- ✅ No collision up to 256 IDs per millisecond
- ✅ Case-insensitive for user input
- ✅ Optional CLI tool for generating IDs
- ✅ Fully unit-tested with PHPUnit
- ✅ PSR-4 autoloaded, Composer ready

---

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

[](#installation)

Install via Composer:

```
composer require marcinjean/minisnowflake
```

---

Basic Usage
-----------

[](#basic-usage)

```
use MarcinJean\MiniSnowflake\MiniSnowflake;

// Generate a new ID
$id = MiniSnowflake::generateId();

echo $id; // Example: "00D2D87XE"

// Validate an ID
if (MiniSnowflake::isValidId($id)) {
    echo "ID is valid!";
}

// Decode an ID
$data = MiniSnowflake::decodeId($id);

print_r($data);
/*
Array
(
    [timestamp] => 1714256780000
    [datetime] => 2025-04-27 22:19:40
    [sequence] => 123
)
*/
```

---

Custom Epoch
------------

[](#custom-epoch)

By default, IDs are generated relative to **January 1st, 2025**.

You can **customize the epoch** globally:

```
// Set a custom epoch (in milliseconds)
MiniSnowflake::setEpoch(strtotime('2024-01-01 00:00:00') * 1000);

// Reset to default epoch (2025-01-01)
MiniSnowflake::resetEpoch();
```

Or pass a **custom epoch per call**:

```
$customEpoch = strtotime('2023-01-01 00:00:00') * 1000;

$id = MiniSnowflake::generateId($customEpoch);
$data = MiniSnowflake::decodeId($id, $customEpoch);
```

---

CLI Usage
---------

[](#cli-usage)

After installing:

```
php bin/generate-id.php
```

Example output:

```
Generated ID: 00D2D87XE
Decoded Info:
- Timestamp: 1714256780000
- Datetime: 2025-04-27 22:19:40
- Sequence: 123

```

You can also specify a custom epoch:

```
php bin/generate-id.php --epoch=1704067200000
```

---
