I think this would suffice your requirement

Find the code sample below as well.

       $json  = '{"currentOver":{"events": []},"matchString":"","currentPlayer":5,"previousOvers":[],"innings":[],"scorecards":[{"batting":{"players":[{"id":16447,"name":"Rahul Roy"},{"id":12633,"name":"Sijal Thomas"},{"id":16446,"name":"Mohammed Reza"},{"id":16509,"name":"Asif Khan"},{"id":12633,"name":"Koyel Dijesh"},{"id":16468,"name":"Shahrook"},{"id":64691,"name":"Shafiq"},{"id":6518,"name":"Ubaidulah"}]}}]}';

       $arr = json_decode($json);

       echo '<pre>';

       $currentPlayer = $arr->currentPlayer;

       echo $arr->scorecards[0]->batting->players[$currentPlayer-1]->name;
