Question: In this exercise, you will create a script that validates whether a credit card number contains only integers. The script will remove dashes and spaces
In this exercise, you will create a script that validates whether a credit card number contains only integers. The 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. Complete the steps below:
1. Open Notepad++ and create a new document. 2. Type the declaration, element, header information, and
element. Use the strict DTD and Validate Credit Card as the content of the
element. 3. Add the following text and elements to the document body: <h1>Validate Credit Card</h1> 4. Add the following script section to the document body: <?php ?> 5. Declare a $CreditCard array that contains three values: an empty string, a valid credit card number with numbers and dashes, and a credit card number with four initial uppercase letter Os. $CreditCard = array( "", "8910-1234-5678-6543", "OOOO-9123-4567-0123"); 6. Add the following statements to iterate through each of the elements in the $CreditCard array to determine if the element contains a value. foreach ($CreditCard as $CardNumber) { if (empty($CardNumber)) echo "<p>This Credit Card Number is invalid because it contains an empty string.</p>"; 7. Add the following else clause to validate the credit card number. The code uses str_replace() functions to remove any dashes and spaces in the number. Then, a nested if...else statement checks whether the new value is numeric. If the number is not numeric, a warning is displayed. If the number is numeric, the modified credit card number is displayed in the Web browser. else { $CreditCardNumber = $CardNumber; $CreditCardNumber = str_replace("-", "", $CreditCardNumber); $CreditCardNumber = str_replace(" ", "", $CreditCardNumber); if (!is_numeric($CreditCardNumber)) echo "<p>Credit Card Number " . $CreditCardNumber . " is not a valid Credit Card number because it contains a non-numeric character. </p>" else echo "<p>Credit Card Number " . $CreditCardNumber . " is a valid Credit Card number.</p>"; } } 8. Save the document as ValidCreditCardLastname.php (Lastname should be your last name) in the Projects directory for Chapter 3. Open it in your Web browser to see how it renders. 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 card numbers are valid.</p> <p> </p> <p>Needing it typed up the way it would look in NotePad++</p> </div>
