A number of useful filters for Twig.
Jasny's Twig Extensions can be easily installed using composer

$twig = new Twig_Environment($loader, $options);
$twig->addExtension(new Jasny\Twig\DateExtension());
$twig->addExtension(new Jasny\Twig\PcreExtension());
$twig->addExtension(new Jasny\Twig\TextExtension());
$twig->addExtension(new Jasny\Twig\ArrayExtension());To use in a symfony project register the extensions as a service.
