variable inside shortcode

Sorry, I looked this in forum without success.
​
In this shortcode
​
{var:array_test_1.0.favouriteFruit}
​
how can I add a variable instead the number 0 ??

Thank You for your reply.

Hi ieraora,
​
It might be possible to use another short code there - I've never tried that. Otherwise I think that you would need to use PHP to extract the values you need.
