Question

 $base_arr =   Array
  (
      1 => Array
          (
          0 => 1,
          1 => 2,
          2 => 5,
          3 => 5
          ),
      3 => Array
          (
          0 => 1,
          1 => 2
          ),
      7 => Array
          (
          0 => 1,
          1 => 4
          )
   );

我想重新组织元素的顺序并将子数组的总数推送到主数组。我想要返回的结果如下：

 $new_arr =   Array(
     0 => 1,
     1 => 2,
     2 => 5,
     3 => 5,
     4 =>13, //this is the total 1+2+5+5 = 13
     5 => 1,
     6 => 2,
     7 => 3,//this is the total 1+2 = 3
     8 => 1,
     9 => 4,
     10 =>5 //this is the total 1+4 = 5

   );

谁能帮助我，谢谢。

Answer 1

这可以为您提供所需的结果：

$new_arr = array();
foreach($base_arr as $base)
{
    $count = 0; //Reset in begin of the loop (with 0)
    foreach($base as $child) 
    {
        $count += $child; //Count the values
        $new_arr[] = $child;
    }
    $new_arr[] = $count; //Put totale in the array
}

print_r($new_arr);

Answer 2

在PHP 5.3中尝试闭包的好机会：

   $new = array();

   array_walk($base_arr, function ($item) use (&$new) {
               $new = array_merge($new, $item);
               $new []= array_sum($item);
            }
    );

    var_dump($new);

Answer 3

使用数组函数：

$new=array();
foreach ($base_arr as $bb) {
  $new=array_merge($new, $bb);
  array_push($new, array_sum($bb));
}

组织元素的顺序并推送子数组的总和
