GUID (Globally Unique Identifier) for PHP

A minimal, dependency-free GUID (Globally Unique Identifier) generator for PHP with a tiny runtime footprint. Frequently also called UUIDs (Universally Unique Identifiers).

---

If this package has been useful to you, GitHub Sponsors is a simple way to support ongoing maintenance, improvements, and future releases.

Requirements

• PHP 8.2+

Compatibility

• Supported and CI-tested on PHP 8.2, 8.3, 8.4, and 8.5.
• Need legacy PHP support below 8.2? Use sudiptpa/guid:^2.0.

Installation

composer require sudiptpa/guid

Usage

Basic usage

<?php

declare(strict_types=1);

use Sujip\Guid\Guid;

$guid = new Guid();

echo $guid->create();
// Example: 2b23924f-0eaa-4133-848e-7ce1edeca8c9

Global helper

<?php

declare(strict_types=1);

echo guid();
// Example: 2b23924f-0eaa-4133-848e-7ce1edeca8c9

echo guid(false);
// Example: {2b23924f-0eaa-4133-848e-7ce1edeca8c9}

Extending generation behavior

Default usage is unchanged. If needed, provide your own generator:

<?php

declare(strict_types=1);

use Sujip\Guid\GeneratorInterface;
use Sujip\Guid\Guid;

final class CustomGenerator implements GeneratorInterface
{
    public function generate(bool $trim = true): string
    {
        return $trim ? 'custom-guid' : '{custom-guid}';
    }
}

$guid = new Guid(new CustomGenerator());

echo $guid->create(); // custom-guid

Public API stability

The package preserves the existing public behavior:

• Sujip\Guid\Guid::create(bool $trim = true): string
• guid(bool $trim = true): string

No runtime dependencies are required, and default usage stays a single class or helper call.
