A robust PHP validation script relies on three primary layers of verification:

Double every second digit. If doubling results in a number greater than 9, subtract 9 from it (or add the two digits together). Sum all the resulting digits.

: Reverse the digits, double every second digit, sum the results (subtracting 9 if a doubled digit is is greater than 9 ), and check if the total sum is divisible by 10. Basic Input Handling Sanitize inputs using functions like to remove spaces or tabs and stripslashes() to prevent basic injection. Example PHP Script Structure cc checker script php
