dexen/mulib
===========

[](#dexenmulib)

Fast UUID v4 generator for PHP: 1MM in 0.7 second.

LZ4 decompressor in pure PHP, good for about 30MB/s. For sake of simplicity checksums are not verified.

[Composer](https://packagist.org/packages/dexen/mulib) and [PSR-4](https://www.php-fig.org/psr/psr-4/) friendly.

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

[](#installation)

```
composer require dexen/mulib

```

Usage
-----

[](#usage)

Basic usage:

```
$uuid_v4 = \dexen\mulib\Uuid::generateUuidV4();
$uuid_v5 = \dexen\mulib\Uuid::generateUuidV5($namespace_uuid, $name);
$decompressed = \dexen\mulib\Lz4::decompress(file_get_contents('my-data.lz4'));
```

An lz4cat replacement is available for shell use:

```
lz4cat-php < my-data.lz4 > my-data

```

Consider defining a helper

```
function generate_uuid_v4() : string
{
	return \dexen\mulib\Uuid::generateUuidV4();
}
```
