The Luhn algorithm only checks if a number is mathematically possible. To verify if a card is open, active, and contains funds, you must use a payment gateway API like Stripe or PayPal.

9) $digit -= 9; $sum += $digit; return ($sum % 10 == 0); // Example Usage $testCard = "4111111111111111"; // Standard Visa Test Number if (validateCC($testCard)) echo "This is a mathematically valid card number."; else echo "Invalid card number."; ?> Use code with caution.
