This library is an implementation of ShortId for PHP.

Installation

Install the library via Composer:

composer require pugx/shortid-php

Usage

ShortId is a PHP library that generates short, unique, and random strings. It's useful in scenarios where you need concise identifiers, such as URL shortening or generating unique keys.

Basic usage

Just call PUGX\Shortid\Shortid::generate() to get a random string with default length 7, like "MfiYIvI".

use PUGX\Shortid\Shortid;

require_once __DIR__.'/vendor/autoload.php';

$id = Shortid::generate();

Advanced usage

For more control, you can customize the alphabet and length using the Factory class.

Default alphabet uses all letters (lowercase and uppercase), all numbers, underscore, and hypen.

use PUGX\Shortid\Factory;
use PUGX\Shortid\Shortid;

require_once __DIR__.'/vendor/autoload.php';

$factory = new Factory();
// alphabet string must be 64 characters long
$factory->setAlphabet('é123456789àbcdefghìjklmnòpqrstùvwxyzABCDEFGHIJKLMNOPQRSTUVWX.!@|');
// length must be between 2 and 20 (default is 7)
// of course, a lower length is increasing clashing probability
$factory->setLength(9);
Shortid::setFactory($factory);

$id = Shortid::generate();

As alternative, you can customize single generations:

use PUGX\Shortid\Shortid;

require_once __DIR__.'/vendor/autoload.php';

$id9 = Shortid::generate(9, 'é123456789àbcdefghìjklmnòpqrstùvwxyzABCDEFGHIJKLMNOPQRSTUVWX.!@|');
$id5 = Shortid::generate(5);

More readable strings

Sometimes, you want to avoid some ambiguous characters, like B/8 or I/l (uppercase/lowercase). In this case, you can pass a third parameter true to generate method. Notice that in this case the alphabet will be ignored, so it makes sense to pass a null one.

Example:

use PUGX\Shortid\Shortid;

require_once __DIR__.'/vendor/autoload.php';

$id = Shortid::generate(7, null, true);

Pre-defined values

If you need a deterministic string, instead of a random one, you can call directly the class constructor. This could be useful, for instance, when you need pre-defined data for testing purposes.

use PUGX\Shortid\Shortid;

require_once __DIR__.'/vendor/autoload.php';

$myFixedId = new Shortid('5h0r71d');
$anotherFixedId = new Shortid('fooBarZ');

Doctrine

If you want to use ShortId with Doctrine ORM, take a look to ShortId Doctrine type.

Doctrine and Symfony

If you want to use ShortId with Doctrine ORM and Symfony framework, take a look to ShortId Doctrine type bundle.

Dependencies replacement

This library uses a polyfill, so it can be used in environments where the mbstring native extension is not available.

If, instead, your environment is offering that extension, you can avoid installing that polyfill by configuring a replace entry in your composer.json.

The same applies to the randomLib library: if you are using PHP 8.3 or higher, you can replace it, since this library uses the native Random class instead.
