$form_page_id = 1234; $form_page = WikiPage::newFromID( $form_page_id ); $form_text = $form_page->getContent()->getNativeData();This code retrieves the content of the page with ID 1234, assuming that it contains a PageForms form definition. It uses the newFromId method to create a WikiPage object for that page, and then calls the getContent method to retrieve the contents of the page. Finally, the getNativeData method is used to get the contents as a string. Overall, newFromId is a useful method for creating MediaWiki objects based on a page ID, and is commonly used in MediaWiki extensions.
