需要帮助从多维数组中删除空数组值

Question

I was wondering if anyone could help me out, I have a multidimensional array and I need the values removed if they're empty (well, set to 0). Here's my array:

Array
(
    [83] => Array
        (
            [ctns] => 0
            [units] => 1
        )

    [244] => Array
        (
            [ctns] => 0
            [units] => 0
        )

    [594] => Array
        (
            [ctns] => 0
        )

)

And I want to only be left with:

Array
(
    [83] => Array
        (
            [units] => 1
        )

)

If anyone could help me, that would be fantastic! :)

Remove empty items from a multidimensional array in PHP

Edit:

  function array_non_empty_items($input) {
     // If it is an element, then just return it
     if (!is_array($input)) {
       return $input;
     }


    $non_empty_items = array();

    foreach ($input as $key => $value) {
       // Ignore empty cells
       if($value) {
         // Use recursion to evaluate cells 
         $items = array_non_empty_items($value);
         if($items)
             $non_empty_items[$key] = $items;
       }
     }

    // Finally return the array without empty items
     if (count($non_empty_items) > 0)
         return $non_empty_items;
     else
         return false;
   }
