start $io->choice() at option 1

Question

I am using $io->choice() to offer some selections in a RoboFile setup. It uses symfony's $io class.

The options that are given are starting at 0, not 1. Is it possible to offer options starting from 1 instead of 0 or maybe add a "non-selectable option" for the first item? (0 is quite far away from 1,2,3 on the keyboard).

@EternalHour it was unclear to me that the function changes a one-dimensional array into an indexed one. I think my question is more related to the io() function of Symfony. I know how to change indexes - if I know they are there ;) — Patrick, Mar 11 '19 at 12:52

The array you submit to choice() needs to start at 1.

$choices = [];
$choices[1] = 'hdtours';
$choices[2] = 'hdtravel';
$choices[3] = 'boutiqueyachting';

$io->choice('Which installation?', $choices);

Thanks. I did not know that this could be done by array keys. Opens up lots of opportunities :) – Patrick Mar 11 '19 at 12:50
