Twig for Developers

Twig utilizes a central object known as the environment (which is of class Twig Environment). This class instances are utilized to store the extensions and configuration and are taken under use to load templates from the file system or various other locations.

Most apps will build one object of Twig Environment on application initialization & utilize this to load templates. In several cases, it’s however helpful to have manifold environments side by side, in case diverse configurations are under use.

The easiest way to configure Twig in order to load templates for your app looks approximately like this:


// Load our autoloader
require_once __DIR__.'/vendor/autoload.php';

// Specify our Twig templates location
$loader = new Twig_Loader_Filesystem(__DIR__.'/templates');

 // Instantiate our Twig
$twig = new Twig_Environment($loader);

This will generate a template environment through the default settings & a loader which look up the templates in the /path/ to /templates/ folder. Diverse loaders are accessible and you can additionally write your own in case you desire to load templates from a database or further resources.
