php - 使用组合相同的键创建新数组

Question

我有以下数组。（var_dump 输出）我想将这些相同的关键元素组合到单个数组中。我怎么做？

 array (size=3)
      'totals' => 
        array (size=3)
          0 => 
            array (size=1)
              'total' => string '4' (length=1)
          1 => 
            array (size=1)
              'total' => string '50' (length=2)
          2 => 
            array (size=1)
              'total' => string '44' (length=2)
      'styles' => 
        array (size=3)
          0 => 
            array (size=1)
              'style' => string '11' (length=2)
          1 => 
            array (size=1)
              'style' => string 'aaa' (length=3)
          2 => 
            array (size=1)
              'style' => string 'bb' (length=3)
      'colors' => 
        array (size=3)
          0 => 
            array (size=1)
              'color' => string '11' (length=2)
          1 => 
            array (size=1)
              'color' => string 'ccc' (length=3)
          2 => 
            array (size=1)
              'color' => string 'ddd' (length=3)

最终输出应该是这样的，

      'totals' => 
        array (size=3)
          0 => 
            array (size=1)
              'total' => string '4' (length=1)  
              'style' => string '11' (length=2)
               'color' => string '11' (length=2)

     'styles' => 
        array (size=3)
          1 => 
            array (size=1)
               'total' => string '50' (length=2)   
                'style' => string 'aaa' (length=3)
                 'color' => string 'bb' (length=3)  

      'colors' => 
        array (size=3)
          2 => 
            array (size=1)
               'total' => string '44' (length=2)
                'style' => string 'ccc' (length=3)
                 'color' => string 'ddd' (length=3)

试试这个 ：

注意：它不是维护键 => 成为数字数组，而是执行功能。

        $array = array("total"=>array(array("total"=>1),array("total"=>2),array("total"=>3)),
                "styles"=>array(array("style"=>4),array("style"=>52),array("style"=>6)),
                "colors"=>array(array("color"=>7),array("color"=>8),array("color"=>9))

);
array_unshift($array, null);
$res = call_user_func_array('array_map', $array);

echo "<pre>";
print_r($res);

输出 ：

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [total] => 1
                )

            [1] => Array
                (
                    [style] => 4
                )

            [2] => Array
                (
                    [color] => 7
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [total] => 2
                )

            [1] => Array
                (
                    [style] => 52
                )

            [2] => Array
                (
                    [color] => 8
                )

        )

    [2] => Array
        (
            [0] => Array
                (
                    [total] => 3
                )

            [1] => Array
                (
                    [style] => 6
                )

            [2] => Array
                (
                    [color] => 9
                )

        )

)

也许这项工作

   for ($j=0; $j < count($your_array) ; $j++) { 

        for ($k=0; $k < count($your_array[0]) ; $k++) {
            if(!isset($sum[$k]))
            {
               $sum[$k]=0;
            }else{
                $sum[$k]=$sum[$k]+$your_array[$j][$k];
            }
        }
    }

所以相同的键将组合在一起，无论大小:)
