How do I update the value in an associative array when the location/destination is represented as a string?

If I have a string like:

$location_to_update = '3,2,1';

how can I convert this string into a location I need to update in an associative array i.e.

$my_array['3']['2']['1'] = 'my new value';

? So separate the commas (explode) and then turn that array into a variable that can update that part of an associate array? Thank you!

Does the string have a variable number of values? – Nick Sep 21 '19 at 07:49

@Nick yes, that's correct it will have a variable number of values – user1190132 Sep 21 '19 at 08:00
