TypeID PHP

A PHP 8.4 implementation of TypeIDs: type-safe, K-sortable, globally-unique identifiers inspired by Stripe IDs.

TypeIDs extend UUIDv7 with a type prefix, giving you better ergonomics for database IDs, API resources, and distributed systems.

Features

• Type-safe — prefix encodes the entity type, preventing ID mix-ups across types
• K-sortable when generated — generated IDs with the same prefix sort chronologically via UUIDv7
• Compact — 26-char Crockford base32 suffix vs 36 chars for a standard UUID string
• URL-safe — only [a-z0-9_] characters, no encoding needed
• No math extensions — base32 uses pure bit manipulation, with no GMP or bcmath requirement

Requirements

• PHP 8.4+

Installation

composer require jewei/typeid-php

Usage

use TypeID\TypeID;

// Generate a new K-sortable TypeID
$id = TypeID::generate('user');
echo $id;          // user_01jsnsf2g7e2saxdjvz3j6tc3x
echo $id->prefix;  // user
echo $id->suffix;  // 01jsnsf2g7e2saxdjvz3j6tc3x
echo $id->toUuid(); // 01966b97-8a07-70b2-aeb6-5bf8e46d307d

// Parse from a string
$id = TypeID::fromString('user_01jsnsf2g7e2saxdjvz3j6tc3x');
echo $id->prefix;  // user

// Encode an existing UUID
$id = TypeID::fromUuid('01966b97-8a07-70b2-aeb6-5bf8e46d307d', 'invoice');
echo $id; // invoice_01jsnsf2g7e2saxdjvz3j6tc3x

// Zero/nil TypeID — useful as a sentinel value
$zero = TypeID::zero('user');
echo $zero->isZero(); // true
echo $zero->isNonZero(); // false

// Equality check
$a = TypeID::fromString('user_01jsnsf2g7e2saxdjvz3j6tc3x');
$b = TypeID::fromString('user_01jsnsf2g7e2saxdjvz3j6tc3x');
echo $a->equals($b); // true

// Round-trip a UUID stored in a binary(16) database column
$uuidBytes = TypeID::generate('user')->bytes();
$binaryId = TypeID::fromBytes($uuidBytes, 'user');
$uuidBytes = $binaryId->bytes();

The package uses ramsey/uuid to generate standards-compliant UUIDv7 values. Encoding and decoding are implemented locally without optional math extensions.

fromUuid() also accepts valid non-v7 UUIDs for interoperability. Those imported values—and the nil value returned by zero()—do not gain UUIDv7 chronological ordering merely by being encoded as TypeIDs.

Caller-invalid input throws TypeID\Exception\ValidationException, which extends InvalidArgumentException. TypeID\Exception\ConstructorException is reserved for UUID generation failures. Both implement TypeID\Exception\TypeIDException.

Format

user_01jsnsf2g7e2saxdjvz3j6tc3x
^^^^  ^^^^^^^^^^^^^^^^^^^^^^^^^^
│     └─ 26-char Crockford base32 (encodes a 128-bit UUIDv7)
└─ prefix: lowercase entity type label (0–63 chars)

The prefix is separated from the suffix by _. When no prefix is used, the TypeID is just the bare 26-char suffix. Multiple underscores are allowed in the prefix (post_category_01jsnsf2g7…); the last underscore is always the delimiter.

Examples

TypeID	Prefix	Suffix
01jsnsf2g7e2saxdjvz3j6tc3x	(none)	01jsnsf2g7e2saxdjvz3j6tc3x
user_01jsnsf2g7e2saxdjvz3j6tc3x	user	01jsnsf2g7e2saxdjvz3j6tc3x
post_category_01jsnsf2g7e2saxdjvz3j6tc3x	post_category	01jsnsf2g7e2saxdjvz3j6tc3x
