在PHP中合并具有相同ID值的数组元素

Question

我在PHP中有下面的数组。 Id和Total键对于相同的Id值是相同的。

Array 
(
    [0] => Array 
     (
      [id] => 1 
      [total] => 100 
      [line] => books 
      [value] => 10 
     ) 
    [1] => Array 
     (
      [id] => 1 
      [total] => 100 
      [line] => cars 
      [value] => 50 
     ) 
    [2] => Array 
     (
      [id] => 1 
      [total] => 100 
      [line] => cover 
      [value] => 30 
     ) 
    [3] => Array 
     (
      [id] => 2 
      [total] => 80 
      [line] => books 
      [value] => 5 
     ) 
    [4] => Array 
     (
      [id] => 2 
      [total] => 80 
      [line] => cover 
      [value] => 35 
     ) 
    [5] => Array 
     (
      [id] => 2 
      [total] => 80 
      [line] => cars 
      [value] => 40 
     ) 

）

我想合并数组内线路和Value元素。 为了说明我看到的结果是下面的数组。

Array 
(
    [0] => Array 
     (
      [id]  => 1 
      [total] => 100 
      [details] => Array 
       (
        [0] => Array 
         (
         [line] => books 
         [value] => 10 
        ) 
        [1] => Array 
         (
         [line] => cars 
         [value] => 50 
        ) 
        [2] => Array 
         (
         [line] => cover 
         [value] => 30 
        ) 
       ) 
     )      

    ) 
    [1] => Array 
     (
      [id]  => 2 
      [total] => 80 
      [details] => Array 
       (
        [0] => Array 
         (
         [line] => books 
         [value] => 5 
        ) 
        [1] => Array 
         (
         [line] => cars 
         [value] => 35 
        ) 
        [2] => Array 
         (
         [line] => cover 
         [value] => 40 
        ) 
       ) 
     )      
    ) 

我正在使用PHP。谢谢你的帮助。

不够好无聊地做你的工作\功课你：

$out=array(); 
foreach($array as $x){ 
    $out[$x['id']]['id']=$x['id']; 
    $out[$x['id']]['total']=$x['total']; 
    $out[$x['id']]['details'][]=array('line'=>$x['line'],'value'=>$x['value']); 
} 

注：

• 使用id作为了重点，可以加入我们自己的，但是这将工作 罚款。
• ID和总将在（每个键）每个回路被覆盖，但是这不是什么大不了的
• 线\值中有自己的细节阵列增加
