PHP парсинг JSON

Есть JSON, который тянется с https://zkillboard.com/api/kills/corporationID/1000107/limit/10/
Сам JSON не бросаю - он огромный
никак не могу его распарсить.

$jsons = file_get_contents('kills.json'); /* сохранил файлик с JSON и подгружаю */
$allkils = json_decode($jsons, true);
   var_dump ($allkils);
echo $allkils[1]['damage_taken'];

не работает
как получить доступ, если здесь 10 одинаковых JSON, но без номерации и пр.?
var_dump выдает
