PHP Community Marketing Expert Interview Question:

Suppose we receive a form submitted by a post to subscribe to a newsletter. This form has only one field, an input text field named email. How would we validate whether the field is empty? Print a message "The email cannot be empty" in this case?

<?php
if(empty($_POST['email'])){
echo "The email cannot be empty";
}
?>
