Check if a multidimensional array has any non-empty leaf nodes

How can I check an array recursively for empty content like this example:

Array
(
    [product_data1] => Array
        (
            [0] => Array
                (
                    [title] => 
                    [description] => 
                    [price] => 
                )

        )
    [product_data2] => Array
        (
            [0] => Array
                (
                    [title] => 
                    [description] => 
                    [price] => 
                )

        )

)

The array is not empty but there is no content. How can I check this with a simple function?

function is_array_empty($InputVariable)
{
   $Result = true;

   if (is_array($InputVariable) && count($InputVariable) > 0)
   {
      foreach ($InputVariable as $Value)
      {
         $Result = $Result && is_array_empty($Value);
      }
   }
   else
   {
      $Result = empty($InputVariable);
   }

   return $Result;
}
