ZF2 - How to enable Twig's Debug / Dump function

Question

Does anyone one know where to enable Twig's dump function in ZF2?

I've looked all over Google and I can't find anything that really relates to this issue. I would have though the ZFC-Twig module would have it right in their config but it doesn't appear to be.

Thanks

Answer 1

According to Twig documentation, you need to activate Twig_Extension_Debug extension to have this function available.

In ZfcTwig module just add this extension to config (doc):

'zfctwig' => [
    'extensions' => [
        'Twig_Extension_Debug',
    ],
],

Answer 2

If you're using Zfc-Twig, you can enable debug feature by enabling it through environment_options like this:

<?php

// enable debug
return array(
    'zfctwig' => array(
        'environment_options' => array(
            'debug'         => true
        )
    )
);
