What happens when a form submitted to a PHP script contains two elements with the same name?
The value of the second element overwrites the value of the first in the appropriate superglobal array
Correct:
The value of the second element overwrites the value of the first in the appropriate superglobal array
PHP simply adds elements to the appropriate superglobal array as they are retrieved from the query string or POST information. As a result, if two elements have the same name, the first one will just be overwritten by the second. Therefore, Answer C is
correct.
