README

Validates popular debit and credit cards numbers against regular expressions and Luhn algorithm. Also validates the CVC and the expiration date.

Since original project seems to be abandoned, this fork is made to support other existing repos with compatible namespaces such as rap2hpoutre/laravel-credit-card-validator which also appears to be abondoned. I forked it to selay/laravel-credit-card-validator

Requirements

PHP 7.0+.

Require the package in composer.json

"require": {
    "selay/php-credit-card-validator": "4.*"
},

Usage

Validate a card number knowing the type:

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

Output:

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

Validate a card number against several types:

$card = CreditCard::validCreditCard('5500005555555559', [CreditCard::TYPE_VISA, CreditCard::TYPE_MASTERCARD]);
print_r($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

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

Output:

bool(true)

Validate the expiration date

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

Output:

bool(false)
