In code

Validate Numbers

This validator uses the Luhn Algorithm

$validator = new Plansky\CreditCard\Validator();
$validator->isValid('57234651187928922');
// true

Generate Random Numbers

Totally random

$generator = new Plansky\CreditCard\Generator();
$generator->single();
// 99119662018492824

Prefix

You can generate a random number using a brand prefix.

$generator = new Plansky\CreditCard\Generator();
$generator->single(301); // Generates a DINERS number
// 30192056094873699

Length

Some brands have different number length.

$generator = new Plansky\CreditCard\Generator();
$generator->single(347, 15); // Generates an AMEX number
// 3479966030620031

Generating Lots

Using same parameters of generate method, except for the first parameter that is the amount of numbers that you want to generate, you can generate a lot of numbers at once

$generator = new Plansky\CreditCard\Generator();
$generator->lot(10, 347, 15); // Generates 10 AMEX numbers
// array(
//   0 => '3479132843454361',
//   1 => '3479587605801416',
//   2 => '3479861510504500',
//   3 => '3479130090772634',
//   4 => '3479427298826638',
//   5 => '3479894458677616',
//   6 => '3479713475691154',
//   7 => '3479468840371814',
//   8 => '3479219690811825',
//   9 => '3479326005723791'
// )
