$twig = new Twig_Environment($loader); $twig->addGlobal('app_name', 'My Awesome App');
$twig = new Twig_Environment($loader); $globals = [ 'app_name' => 'My Awesome App', 'version' => '1.0.0', 'author' => 'John Smith', ]; $twig->addGlobals($globals);This code creates a new Twig environment and adds multiple global variables at once using the addGlobals method. This is a convenient way to add many variables at once without having to call addGlobal for each one. The Twig_Environment class and the addGlobal method are part of the Twig package library, which is a popular PHP templating engine used for rendering HTML templates.
