In this project, you will create a script that validates whether a credit card number contains only integers. Th e script will remove dashes and spaces from the string. After the dashes and spaces are removed,the script should reject the credit card number if it contains any other non-numeric characters.
echo “<p>Credit Card Number ” .
$CreditCardNumber . ” is a valid
Credit Card number.</p>”;
8. Save the document as ValidateCreditCard.php in the Projects directory for Chapter 3 and upload the fi le to the server.
9. Open ValidateCreditCard.php in your Web browser by enter-ing the following URL:
http://<yourserver>/PHP_Projects/Chapter.03/Projects/ValidateCreditCard.php Test the script to see if it displays a message for an empty string, strips dashes and spaces from the credit card numbers, and identifies which credit cardnumbers are valid.
