A great script integrates cURL requests to fetch data from live BIN databases. This allows your application to determine if a card is a Credit or Debit card, its prepaid status, country of origin, and the exact name of the issuing bank (e.g., Chase, Barclays). 2. Multi-Format Input Parsing
function isValidLuhn($number) settype($number, 'string'); $sum = 0; $len = strlen($number); $offset = 1 - ($len % 2); for ($i = 0; $i < $len; $i++) if (($i + $offset) % 2) $sum += $number[$i]; else $double = $number[$i] * 2; $sum += ($double > 9) ? $double - 9 : $double; return ($sum % 10 === 0); Use code with caution. 2. Advanced Card Validation: Identifying Type and BIN
Instead of processing raw card details on your server—which drastically increases your liability—use Stripe's PHP SDK to create a SetupIntent or PaymentMethod.
If you are looking to build a secure checkout, I can help you (like Stripe or PayPal) that handle this validation for you. Would that be helpful? cc-checker · GitHub Topics

This entire process happens behind the scenes in milliseconds. It is not a tool for carding, but a critical layer of validation for any legitimate online store.
