// Get the "required" attribute of a form field $isRequired = $form->get('fieldName')->getAttribute('required');
// Get the "class" attribute of a form element $classes = $form->getAttribute('class');In this example, we are getting the value of the "class" attribute of a form element. The getAttribute() method returns the value of the attribute as a string, which can be used to add or remove classes from the element. The Symfony\Component\Form\FormInterface is part of the Symfony Form component, which provides a flexible and powerful way to build HTML forms in PHP.
