README
Overview
Replacement of hidehalo/nanoid-php to work with PHP 7.1+
A tiny (179 bytes), secure URL-friendly unique string ID generator for JavaScript
Safe. It uses cryptographically strong random APIs and guarantees a proper distribution of symbols.
Small. Only 179 bytes (minified and gzipped). No dependencies. It uses Size Limit to control size.
Compact. It uses more symbols than UUID (A-Za-z0-9_-) and has the same number of unique options in just 21 symbols instead of 36.
Install
Via Composer
composer require better/nanoid
Usage
Normal
The main module uses URL-friendly symbols (A-Za-z0-9_-) and returns an ID with 21 characters (to have the same collisions probability as UUID v4).
use Better\Nanoid\Client; use Better\Nanoid\GeneratorInterface; $client = new Client(); # default random generator echo $client->produce($size = 32); # more secure generator with more entropy echo $client->produce($size = 32, true);
Custom Alphabet or Length
$client = new Client('0123456789abcdefg'); $client->produce();
Alphabet must contain 256 symbols or less. Otherwise, the generator will not be secure.
Custom Random Bytes Generator
# PS: anonymous class is new feature when PHP_VERSION >= 7.0 $client = new Client(); echo $client->produceUsing(new class implements GeneratorInterface { /** * @inheritDoc */ public function random(int $size): string { $ret = []; while ($size--) { $ret[] = mt_rand(0, 255); } return $ret; } });
random
callback must accept the array size and return an array with random numbers.
