Twig - Dynamic array key

Question

Currently working on a tool built on Symfony. I am iterating over an array of configuration settings. The thing I want to achieve seemed simple enough:

I am trying to obtain a certain value. One of the keys has to be dynamic though. Below is a working example without the key being dynamic.

{% set id = tmod_config.content_1.id %}

("content_1" being the key in question)

The number at the end of the key has to be dynamic. I have tried a couple of things but wasn't able to achieve this. Up to this point I have access to the dynamic value, it just needs to be turned into a functioning key.

Any suggestions?

@Yoshi It's a parameter that was passed with the rendering of the template. Anyway, I have managed to solve the problem just now. Thanks for thinking along! — spacellama

As it is an array you could use either..

{% set id = tmod_config[content_1].id %}

or

{% set id = attribute(tmod_config, content_1).id %}

It can easily be done like this:
