PHP获取每个多维数组的结果分离

Question

我有多维数组，从数据库genereted，想一些ITM2 + itm3为每个阵列，并获得总喜欢多维数组：

array 5 = 1740 array 6 = 2700

这是我的多维阵列的一部分：

$arrays = Array 
(
    [5] => Array 
    (
     [0] => stdClass Objectd(
       [itm1] => 19 
       [itm2] => 500 
       [itm3] => 100 
      ) 

     [1] => stdClass Object(
       [itm1] => 20 
       [itm2] => 700 
       [itm3] => 100 
      ) 

     [2] => stdClass Object(
       [itm1] => 21 
       [itm2] => 240 
       [itm3] => 100 
      ) 
    ) 
    [6] => Array(
     [0] => stdClass Object(
       [itm1] => 22 
       [itm2] => 1500 
       [itm3] => 100 
      ) 
     [1] => stdClass Object(
       [itm1] => 23 
       [itm2] => 1000 
       [itm3] => 100 
      ) 
    ) 
) 

Answer 1

我必须集中精力多一点:) 的解决方案是：

  foreach($array as $key1=>$val1){ 
       $sum_to_values =0; 
       $sum_to_array =0; 
       foreach($val1 as $val2){ 
        $sum_to_values = $val2->itm2 * $val2->itm3; 
        $sum_to_array +=$sum_to_values; 
       }echo $sum_to_array.'<br/>'; 
      } 

谢谢！
