  1. Hi! Why do we need this: $gender = 'a'; //create a false value to test against The script works well without it, please explain!
  2. Hello! Please explain to me how gender validations from scripts 2.3 differ from the nested one in script 2.4. I have this in 2.3 (updated with NULL coalescing operator while practicing Pursue section): $gender = $_REQUEST['gender'] ?? NULL; if ($gender == 'M') { $greeting = '<p><strong>Good day, Sir!</strong></p>'; } elseif ($gender == 'F') { $greeting == '<p><strong>Good day, Madam!</strong></p>'; } else { $gender = NULL; echo '<p class="error">Gender must be either "M" or "F"!<
  3. After your new hint, I immediately came up with the solution, which now seems so obvious! Thank you!
  4. Hello! I stuck into this question, please help me to solve it: Rewrite the gender conditional in handle_form.php (Script 2.4) as one conditional instead of two nested ones. Hint: You’ll need to use the AND operator.
  5. Hi to all! This script works identically without ! empty conditional, am I right? if (! empty ($_POST['name']) && ! empty ($_POST['email']) && ! empty ($_POST['comments'])) { } the same as: if (($_POST['name']) && ($_POST['email']) && ($_POST['comments'])) { } Thank you!
