What are the benefits of using PEAR-Quickform for handling mandatory fields in PHP forms?

When creating forms in PHP, it is important to handle mandatory fields to ensure that users provide necessary information. PEAR-QuickForm is a PHP library that simplifies form creation and validation, making it easy to set required fields and display error messages if they are not filled out.

<?php
require_once 'HTML/QuickForm.php';

$form = new HTML_QuickForm('myForm');

$form->addElement('text', 'name', 'Name:', ['required' => true]);
$form->addElement('text', 'email', 'Email:', ['required' => true]);

if ($form->validate()) {
    // Form submission logic here
} else {
    $form->display();
}
?>
