$content = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed vitae enim ut dolor sagittis euismod sit amet vel sapien."; $article->setContent($content);
$markdown = "# My Article\n\nHello world!\n"; $html = $parsedown->text($markdown); $article->setContent($html);In this example, we have a variable `$markdown` that holds some text in Markdown format. We use a library (in this case, Parsedown) to convert the Markdown into HTML, which we store in the `$html` variable. We then use the `setContent` method to set the content of an article to the HTML content. Based on the examples, it's difficult to determine a specific package library that provides the `setContent` method, as it could be implemented in a variety of libraries. However, it is commonly used in content management systems (CMS) and web development frameworks.
