v1,v3,v4,v5,v6,v7,v8) - ULID (monotonic and random modes)
- Snowflake, Sonyflake, Randflake, TBSL
- TypeID, ObjectID, NanoID, RandomId, CUID2, KSUID, XID
- Opaque and deterministic IDs
- Value objects and comparator utilities
- Binary conversion and base encoders (
16,32,36,58,62) - Pluggable sequence providers (filesystem, memory, PSR-16 cache, callback)
Requirements
- PHP
>=8.2 - A 64-bit PHP runtime
Installation
composer require infocyph/uid
Namespaced generator functions are autoloaded via src/functions.php.
Quick Usage
<?php use Infocyph\UID\Id; use Infocyph\UID\CUID2; use Infocyph\UID\NanoID; $uuid = Id::uuid(); // default UUID strategy (v7) $ulid = Id::ulid(); $snowflake = Id::snowflake(); $sonyflake = Id::sonyflake(); $tbsl = Id::tbsl(); $randflake = \Infocyph\UID\Randflake::generate( nodeId: 42, leaseStart: time() - 5, leaseEnd: time() + 300, secret: 'super-secret-key', ); $nanoid = NanoID::generate(21); $cuid2 = CUID2::generate(24);
<?php use Infocyph\UID\UUID; $uuid = UUID::v7(); $ok = UUID::isValid($uuid); $parsed = UUID::parse($uuid); $bytes = UUID::toBytes($uuid); $roundTrip = UUID::fromBytes($bytes); $base58 = UUID::toBase($uuid, 58); $decoded = UUID::fromBase($base58, 58);
The shared byte-level encoder is available as
Infocyph\UID\Support\BaseEncoder for bases 16, 32, 36, 58, and 62.
