$form = new Form('contact-form'); $form->addField('name', 'text', array( 'label' => 'Name', 'required' => true )); $form->addField('email', 'email', array( 'label' => 'Email', 'required' => true )); $form->addField('message', 'textarea', array( 'label' => 'Message', 'required' => true )); if ($form->isValid()) { // Send email using form data }In this example, we create a new `Form` object with an ID of 'contact-form' and then add three input fields to the form using the `addField()` method. Each field has a label, input type, and optional validation rules. Finally, we check if the form data is valid and if so, send an email with the form data. The PHP Form model is part of the Laravel framework, a popular PHP web application framework. However, it can also be used independently of Laravel in any PHP project.
