如何渲染Twig模板而不将任何数组传递给render（）方法？

Question

I am using Twig a few days, and it's very nice, but now I am in a situation where I need to render a template without passing any array to the render() method.

I am using:

echo $template->render();

but Twig raises an exception because I NEED to pass some array to the render. So I tried:

echo $template->render(array(''=>''));

and it works, but it's so ugly.

Any tips about this? Thanks!

Instead of passing an array that contains an empty string element, you should also be able to pass the template an empty array:

echo $template->render(array());

Apart from that, you are probably using Twig this way:

$template = $twig->loadTemplate('index.html.twig');
echo $template->render(array('the' => 'variables', 'go' => 'here'));

The Twig documentation suggests an easier way to do the same:

echo $twig->render('index.html.twig', array('the' => 'variables', 'go' => 'here'));

The additional benefit is that the render method of the Twig_Environment class allows you to omit the second argument (it defaults to an empty array), so now you can simply do this:

echo $twig->render('index.twig.html');
