What are the advantages and disadvantages of using hidden inputs to pass validated data between pages in PHP?

Using hidden inputs to pass validated data between pages in PHP can be advantageous because it allows for the data to be securely transferred without exposing it in the URL. This method also ensures that the data is validated before being passed to the next page. However, a disadvantage is that hidden inputs can be manipulated by users, so additional security measures should be implemented to prevent data tampering.

// Page 1: Form submission with validated data
$validated_data = validate_data($_POST['input_data']);
echo '<form method="post" action="page2.php">';
echo '<input type="hidden" name="validated_data" value="' . $validated_data . '">';
echo '<input type="submit" value="Submit">';
echo '</form>';

// Page 2: Retrieving validated data
$validated_data = $_POST['validated_data'];
// Use the validated data as needed
