php – Using a custom function in Twig

Use getFunctions() instead of getFilters()

public function getFunctions()
    return array(
        new Twig_SimpleFunction(server_time_zone, array($this, getServerTimeZone)),

Twig filters are used to filter some value.

{{ some value | filter_name_here }}

Btw, you can define both filters and functions in the same class.

Instead of getFilters, override getFunctions and use Twig_Function_Method instead of Twig_Filter_Method.

In the newer versions of Twig he should be using Twig_SimpleFunction instead of Twig_Function_Method and Twig_SimpleFilter instead of Twig_Filter_Method, since Twig_*_Method are deprecated (I am using Twig v. 1.24.0 along with Symfony 2.8.2)
