PHP Credit Card Number Validator Library

• Download the Library and save it as "cccheck.inc.php"
• In your PHP application, "include" it, like this:
  <?php include_once("/path/to/cccheck.inc.php"; ?>
• Then, anywhere in your program, you can make calls to the library, as follows:
  Call the "validateCC" function with a credit card number. Returns card type and a 1 on valid card numbers, null on invalid ones.
  
  $ccnumber = $_POST['credit_card_number'];
list($type, $valid) = validateCC($number);
if ( $valid ) {
    // Do something fun with the card
  echo "Number: <b>$ccnumber</b> ... Type: <b>$type</b> ... Valid: <b>$valid</b>";
}
else {
  // Return some sort of error
}
