How to separate elements from JSON array

Question

I am executing a php script and getting the following results:

[{"0":"1010100000100000100","nonnull_columns":"1010100000100000100"}]

can I extract the string quoted in second quote i.e. 1010100000100000100??

It's an object inside an array.

$json_string = '[{"0":"1010100000100000100","nonnull_columns":"1010100000100000100"}]';
$json_decoded = json_decode($json_string);
$first_element = $json_decoded[0];
$nonnull_columns = $first_element->nonnull_columns;

Above code can of course be shortened.
