Check if value exists in array TWIG

I've got an string loaded from my DB, and global variable from my config.yml. I want to check if variable is a part of array given below:

app.user.role ='["1","2","3","4","5","6","7","8","9","10","11"]'

I can't change that. It have to look like this.

I was checking it like this: {% if VARIABLE in app.user.role %}

Global VARIABLE is an integer (and I can't change that)

But when for example VARIABLE = 1 my statement returns true, because in app.user.role we can find four 1 (in "1","10","11"), but i want to find it just in "1" not in "10","11".

What I want is to convert app.user.role to array or find another way to check if variable is an element of my pseudo array.

I was trying to iterate through for loop but app.user.role but app.user.role is not an array (actualy it is, but with one value ["1","2","3","4","5","6","7","8","9","10","11"]).

The string looks like JSON. You can create a Twig Extension class and register there a function that simply returns in_array:

<?php

class MyExtension extends Twig_Extension
{
    public function getFunctions()
    {
        return [
            new Twig_SimpleFunction(
                'inarray',
                [$this, 'inArray']
            ),
        ];
    }

    /**
     * @param int $variable
     * @param string $appUserRole
     *
     * @return bool
     */
    public function inArray(int $variable, string $appUserRole): bool
    {
        return in_array($variable, json_decode($appUserRole));
    }
}

Then in the template:

{% if inarray(VARIABLE, app.user.role) %}

Found a solution. Not the best but it works.

{% set check = '"'~VARIABLE~'"' %}
{% if check in app.user.role %}

Now it's working...
