// create an ILIAS form object $form = new ilPropertyFormGUI(); // add some form elements $form->setTitle("Example Form"); $form->addText("first_name", "First Name"); $form->addText("last_name", "Last Name"); // prepare the output $output = ilUtil::prepareFormOutput($form->getHTML()); // display the form echo $output;In this example, the ILIAS library is used to create a form object and add some form elements. The `ilUtil::prepareFormOutput()` function is then used to prepare the form output for display. The resulting HTML is then displayed on the page. This function is part of the ILIAS core library, which is included with the ILIAS learning management system. However, it can also be used in standalone PHP applications with the appropriate dependencies installed.
