Disclaimer

All the codes here come form 2 repository-

• https://github.com/rap2hpoutre/laravel-credit-card-validator/

They should meet you requirements. I had to make this package to solve some very specific requirements.

PHP Usage

Validate a card number knowing the type:

$card = CreditCard::validCreditCard('5500005555555559', 'mastercard');
print_r($card);

Output:

Array
(
    [valid] => 1
    [number] => 5500005555555559
    [type] => mastercard
)

Validate a card number and return the type:

$card = CreditCard::validCreditCard('371449635398431');
print_r($card);

Output:

Array
(
    [valid] => 1
    [number] => 371449635398431
    [type] => amex
)

Validate the CVC

$validCvc = CreditCard::validCvc('234', 'visa');
var_dump($validCvc);

Output:

bool(true)

Validate the expiration date

$validDate = CreditCard::validDate('2013', '07'); // past date
var_dump($validDate);

Output:

bool(false)

Add this to your validation rules:

// Add this in your controller method
$this->validate($request, [
    'credit-card-number' => 'required|ccn',
    'credit-card-date' => 'required|ccd',
    'credit-validation-code' => 'required|cvc',
]);
