Code to test PHP Keygen package installation by just generating some random keys.

keygen-test.php

<?php

require __DIR__ . '/vendor/autoload.php';
use Keygen\Keygen;

$id_12 = Keygen::numeric(12)->generate();
$id_16 = Keygen::numeric()->generate();

$alnum = Keygen::alphanum(15)->generate();
$token = Keygen::token(28)->generate();

$bytes = Keygen::bytes(20)->generate();
$hex = Keygen::bytes(20)->hex()->generate();

echo $id_12; // 011683218639
echo $id_16; // 9352941287643963

echo $alnum; // TFd5X74Pr9ZOiG2
echo $token; // 4HE1xQz+4ks0Td128KSO/kBivd79

echo $bytes; // (some random byte chars)
echo $hex; // 9f802a80aaf4b5e89e14
