Обработка/фильтр Json с циклом foreach с использованием значений

У меня есть массив данных, который я преобразовал в json, разделив ключи, используемые для каждого цикла.

Данные:

$data = Array

Следующее, что я хочу сделать, это сбросить ключи или целые внутренние объекты json.

Keeping in mind the following conditions:

1.If all the keys in the objects are 0 then the entire object will be removed (easy part).

2.If a key in the object has any value other than 0 , the object should not be removed and the key with "0" value should also be there.

я пробовал разделить значение и использовать условия для проверки 0 или нулевых значений, но проблема в том, что он удаляет все ключи, которые имеют 0 значений, таким образом, не выполняя условие 2 для кода.

   $vars = $data;
   $count = "";
   $finalArray = array();
   foreach ($vars as $keys => $values) {
     foreach ($values as $k => $v) {
       foreach ($v as $ke => $ve) {
               if ($keys == "table6") {
                  $count = (array)$v;    
                  foreach ($count as $ck => $cv) {
                    if ($cv != "0")
                    {
                     $flag = true;
                     break;
                    }
                  }

         if ($flag == false)
              {
                array_push($finalArray, $count);
              }                         
       }
    }
 }
print_r($finalArray);
die();

Я ожидал, что вывод будет содержать объекты с парами ключ-значение, которые не содержат 0 значений, но здесь все печатается.
