README

PHP Library to use ULID on your application.

• 128-bit compatibility with UUID
• 1.21e+24 unique ULIDs per millisecond
• Lexicographically sortable!
• Canonically encoded as a 26 character string, as opposed to the 36 character UUID
• Uses Crockford's base32 for better efficiency and readability (5 bits per character)
• Case insensitive
• No special characters (URL safe)
• Monotonic sort order (correctly detects and handles the same millisecond)

Installation

You can install the package via composer:

composer require guifelix/php-ulid

Usage

Generate

use Guifelix\Ulid;

$ulid = Ulid::generate(); // Accept boolean as a parameter for lowercase;

echo (string) $ulid; //0001EH8YAEP8CXP4AMWCHHDBHJ
echo $ulid->getTime(); //0001EH8YAE
echo $ulid->getRandomness(); //P8CXP4AMWCHHDBHJ
echo $ulid->isLowercase(); //false
echo $ulid->toTimestamp(); //1561622862

Generate from timestamp

use Guifelix\Ulid;

$ulid = Ulid::fromTimestamp(1561622862); // Accept boolean as a second parameter for lowercase;

echo (string) $ulid; //0001EH8YAEP8CXP4AMWCHHDBHJ

Generate from string (doesn't increment randomness)

use Guifelix\Ulid;

$ulid = Ulid::fromString('0001EH8YAEP8CXP4AMWCHHDBHJ'); // Accept boolean as a second parameter for lowercase;

echo (string) $ulid; //0001EH8YAEP8CXP4AMWCHHDBHJ

Validate

use Guifelix\Ulid;

Ulid::validate('8ZZZZZZZZZP8CXP4AMWCHHDBHI'); // Case insensitve
/**
 * validate Length, Crockford Characters and Time
 * Throws
 *  - InvalidUlidLengthException
 *  - InvalidUlidCharException
 *  - InvalidUlidTimestampException <- Max timestamp is 7ZZZZZZZZZ (281474976710655) or until the year 10889 AD :)
