Usage
Initialize a new Uuid instance with a given UUID string
use Ghostwriter\Uuid\Uuid; $uuid = new Uuid('0000669c-8deb-7fe7-b9cc-692b216999a3'); echo $uuid->toString(); // 0000669c-8deb-7fe7-b9cc-692b216999a3
Generate a new UUID
echo Uuid::new()->toString(); // 0000669c-8f99-711e-9ed0-72a35c3b6fb3
Generate a new UUID with a specific timestamp
echo Uuid::new(new DateTimeImmutable())->toString(); // 0000669c-8faf-7e4b-9ed9-45c4c2b27f07
Compare UUIDs based on their timestamp
$uuid1 = Uuid::new(new DateTimeImmutable('-1 year')); $uuid2 = Uuid::new(new DateTimeImmutable('-1 month')); $uuid3 = Uuid::new(new DateTimeImmutable('-1 week')); $uuid4 = Uuid::new(new DateTimeImmutable('-1 day')); assert(0 === $uuid1->compare($uuid1)); assert(-1 === $uuid1->compare($uuid2)); assert(-1 === $uuid1->compare($uuid3)); assert(-1 === $uuid1->compare($uuid4)); assert(1 === $uuid2->compare($uuid1)); assert(0 === $uuid2->compare($uuid2)); assert(-1 === $uuid2->compare($uuid3)); assert(-1 === $uuid2->compare($uuid4)); assert(1 === $uuid3->compare($uuid1)); assert(1 === $uuid3->compare($uuid2)); assert(0 === $uuid3->compare($uuid3)); assert(-1 === $uuid3->compare($uuid4)); assert(1 === $uuid4->compare($uuid1)); assert(1 === $uuid4->compare($uuid2)); assert(1 === $uuid4->compare($uuid3)); assert(0 === $uuid4->compare($uuid4)); /** @var array{0:UuidInterface,1:UuidInterface,2:UuidInterface,3:UuidInterface} $uuids */ $uuids = [$uuid3, $uuid1, $uuid4, $uuid2]; usort($uuids, static fn (UuidInterface $left, UuidInterface $right): int => $left->compare($right)); assert($uuid1->toString() === $uuids[0]->toString()); assert($uuid2->toString() === $uuids[1]->toString()); assert($uuid3->toString() === $uuids[2]->toString()); assert($uuid4->toString() === $uuids[3]->toString());
