Implementing thorough validation before calling payment gateway APIs reduces unnecessary network traffic and costs associated with invalid requests. The Omnipay payment processing library, for example, recommends calling Helper::validateLuhn($number) before submitting to a gateway.
// Diners Club: starts with 300-305, 36, 38, 39 if (preg_match('/^30[0-5]/', $cardNumber)
: This is the primary checksum formula used to validate various identification numbers.

From the rightmost digit (the check digit), moving left, double the value of every second digit. $masked_card = substr($card, 0, 6)
If you're implementing credit card validation for legitimate purposes, follow these guidelines:
A "CC Checker" (Credit Card Checker) script in PHP is a tool used to verify the validity of credit card numbers. While these can be used for legitimate purposes—such as validating user input on an e-commerce site before processing a payment—they are also frequently associated with "carding" (testing stolen credit card data). 🛡️ Executive Summary
The script uses cURL to mimic a real browser. The critical part is sending an authorization request to a payment API. $masked_card = substr($card
Handling raw credit card data requires strict adherence to Payment Card Industry Data Security Standards. Most self-hosted PHP scripts do not meet these security requirements, risking data leaks. Security Risks:
Card Number:
While legitimate users never fail Luhn, an abnormal amount of Luhn-failed submissions suggests a raw scraper using random number generation.
