In what scenarios would using a hidden field in a form submission be necessary or beneficial in PHP?

Using a hidden field in a form submission can be necessary or beneficial in PHP when you need to pass information from one page to another without displaying it to the user. This can be useful for storing session tokens, user IDs, or other sensitive data that should not be visible in the form itself. 

<form action="process.php" method="post">
  <input type="hidden" name="token" value="<?php echo $_SESSION['token']; ?>">
  <!-- Other form fields here -->
  <button type="submit">Submit</button>
</form>
