A real-world implementation typically performs multiple validations, checking the card number, expiration date, and CVV/CVC. For PHP, the inacho/php-credit-card-validator package is a robust library that handles all of this for you. Install it via Composer and use it to validate a card's number, expiration date, and CVC with a few lines of code. A complete validation process using a dedicated library typically includes the steps outlined below:
: A robust script should iterate through digits, doubling every second digit from the right and summing the results. 2. BIN/IIN Identification
