assign('title', 'My Website'); $template->assign('content', 'Hello, world!'); // Render the template $template->parse('main'); $template->out('main'); ?>In this example, the XTemplate library is first loaded using the `require_once` function. A new instance of the template object is then created, and values are assigned to the `title` and `content` variables using the `assign` function. Finally, the template is rendered using the `parse` and `out` functions. XTemplate is a lightweight and flexible package library that is perfect for small to medium web applications. It provides a powerful and intuitive way to manage templates and streamline the web development process.
