$twig = new \Twig\Environment($loader); $twig->setCache('/path/to/your/cache/directory');
$twig = new \Twig\Environment($loader, [ 'cache' => '/path/to/your/cache/directory', 'auto_reload' => true, ]);Here, `setCache` is being used in conjunction with other settings in the `$options` array passed to the `Twig\Environment` constructor. In addition to setting the cache directory, `auto_reload` is being set to `true`, which means that Twig will regenerate the cache when changes are detected in the templates. Overall, `setCache` is a useful function in the Symfony Twig package library that can help improve performance and reduce server load for sites and applications that rely heavily on template rendering.
