twigHow to use PHP variables in Twig?

Twig is a templating language for PHP, and it allows you to use PHP variables in your Twig templates. To do this, you need to pass the variables to the Twig environment when you create it.

$loader = new Twig_Loader_Filesystem('templates');
$twig = new Twig_Environment($loader);

$name = 'John';
$twig->addGlobal('name', $name);

The above code creates a Twig environment and adds a global variable name with the value John. This variable can now be used in any Twig template.

Hello {{ name }}

Output example

Hello John
