Question
Write a program called week2.php that displays a form that submits to itself. When initially accessed, week2.php displays an HTML form. If the the user POSTs the form, week2.php will simply output the names and values (if any) ofeach of the form elements, and exit. Use htmlspecialchars on the form data that you display. If one of your form fields is unset (i.e., the checkbox), output something like [no value] in place of the value. Copy the following from the class website and use it for your assignment, replacing the just the multi-line comment with the necessary PHP code 1.
