How to embed php in twig

Question

I have a do_shortcut and I need to embed it in a twig template. I tried by coping the code in a php file my-code.php:

Answer 1

About the include part, create a my_code.html.twig file at app/Resources/views/my_code.html.twig and copy-paste your code from my-code.php

Then you can include that code anywhere like :

{% include 'my_code.html.twig' %}

EDIT: tested and working in symfony3
