A

Obviously, if an expected input field was not submitted, there will be no entry in the $_REQUEST array for that field. You may get an execution error, if you are not checking the existence of the expected entries in $_REQUEST. For example, if you copy processing_forms.php to your local Web server, and run your browser with http://localhost/processing_forms.php?name=Joe, you will an error page like this:

You have submitted the following information:
  Name = Joe
  Comments = 
Thank you!

PHP Notice: Undefined index: 
  comment in ...\processing_forms.php on line 3
