shortuuid-php
The PHP implementation of shortuuid.
Installation
composer require pyyoshi/shortuuid-phpor add this library in your composer.json
{
"require": {
"pyyoshi/shortuuid-php": "*"
}
}Usage
import
require dirname(__DIR__) . "/vendor/autoload.php";
require_once 'ShortUUID/Autoloader.php';
\ShortUUID\Autoloader::register();You can then generate a short UUID:
use ShortUUID\ShortUUID;
$su = new ShortUUID();
$su->uuid();
=> "rkQdp5ikpXjraCsrSaysaT"If you prefer a version 5 UUID, you can pass a name (DNS or URL) to the call and it will be used as a namespace (uuid.NAMESPACE_DNS or uuid.NAMESPACE_URL) for the resulting UUID:
use ShortUUID\ShortUUID;
$su = new ShortUUID();
$su->uuid('example.com');
=> "wpsWLdLt9nscn2jbTD3uxe"
$su->uuid('http://www.example.com/');
=> "VSPugLzk4dD4WC7yfAQUzn"To see the alphabet that is being used to generate new UUIDs:
use ShortUUID\ShortUUID;
$su = new ShortUUID();
$su->getAlphabet();
=> "23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"If you want to use your own alphabet to generate UUIDs, use setAlphabet():
use ShortUUID\ShortUUID;
$su = new ShortUUID();
$su->setAlphabet('aaaaabcdefgh1230123');
$su->uuid();
=> "ee120aeh2h3bb010fdfedef2c03efcf3h1ca"shortuuid-php will automatically sort and remove duplicates from your alphabet to ensure consistency:
use ShortUUID\ShortUUID;
$su = new ShortUUID();
$su->setAlphabet('aaaaabcdefgh1230123');
$su->getAlphabet();
=> "0123abcdefgh"If the default 22 digits are too long for you, you can get shorter IDs by just truncating the string to the desired length. The IDs won't be universally unique any longer, but the probability of a collision will still be very low.
To serialize existing UUIDs, use encode() and decode():
use Ramsey\Uuid\Uuid;
use ShortUUID\ShortUUID;
$u = Uuid::uuid4();
$su = new ShortUUID();
$s = $su->encode($u);
$su->decode($s) == $u;
