Php 展平多维数组,php,arrays,multidimensional-array,Php,Arrays,Multidimensional Array,（请不要介意标题，我不知道如何正确命名）我目前有一个多维数组，看起来像这样： Array ( [0] => Array ( [French Navy] => Array ( [84] => 2XL [quantity] => 999 [product_colour_sizes_id] => 36786

（请不要介意标题，我不知道如何正确命名）我目前有一个多维数组，看起来像这样：

Array
(
  [product_colour_sizes_id] => 36790
  [product_colour_sizes_product_id] => 1276
  [product_colour_sizes_option_value_colour_id] => 182
  [product_colour_sizes_option_value_size_id] => 84
  [quantity] => 999
  [product_colour_sizes_name_sizes1] => 2XL => [id1] => 83
  [product_colour_sizes_name_sizes2] => L   => [id2] => 84
  [product_colour_sizes_name_sizes3] => S   => [id3] => 85
  [product_colour_sizes_name_sizes4] => M   => [id4] => 86   
  [product_colour_sizes_name_colours] => French Navy
)

我想做的是，将每次迭代减少到它自己的数组中，这样我就可以以名称的形式访问键值（如果有意义的话）。大概是这样的：

Array
(
  [product_colour_sizes_id] => 36790
  [product_colour_sizes_product_id] => 1276
  [product_colour_sizes_option_value_colour_id] => 182
  [product_colour_sizes_option_value_size_id] => 84
  [quantity] => 999
  [product_colour_sizes_name_sizes1] => 2XL => [id1] => 83
  [product_colour_sizes_name_sizes2] => L   => [id2] => 84
  [product_colour_sizes_name_sizes3] => S   => [id3] => 85
  [product_colour_sizes_name_sizes4] => M   => [id4] => 86   
  [product_colour_sizes_name_colours] => French Navy
)

我用于生成第一个数组的当前php代码如下：

$colours = array();
                        $sizes = array();
                        $color = "";
                        $id = "";
                        $quantity = "";
                        //$count = count($colours);

                        foreach($product_combinations as $key => $product_combination){
                            if($key > -1){
                                if(
                                    $product_combinations[$key+1]['product_colour_sizes_name_colours']
                                    == $product_combinations[$key]['product_colour_sizes_name_colours']
                                  ){

                                    $color  = $product_combinations[$key]['product_colour_sizes_name_colours'];
                                    $id = $product_combinations[$key]['product_colour_sizes_option_value_size_id'];
                                    $sizes[$id] = $product_combinations[$key]['product_colour_sizes_name_sizes'];
                                    $quantity = $product_combinations[$key]['quantity'];
                                    $sizes['quantity'] = $quantity;

                                    /* Dont forget theses*/
                                    $sizes['product_colour_sizes_id'] = $product_combination['product_colour_sizes_id'];
                                    $sizes['product_colour_sizes_product_id'] = $product_combination['product_colour_sizes_product_id'];
                                    $sizes['product_colour_sizes_option_value_colour_id'] = $product_combination['product_colour_sizes_option_value_colour_id'];
                                    $sizes['product_colour_sizes_option_value_size_id'] =$product_combination['product_colour_sizes_option_value_size_id'];

                                } else {
                                    array_push($colours, 
                                    array(
                                        $color => $sizes

                                    ));

                                    unset($sizes);
                                }
                            }
                        }

如何执行此操作？

下面是将输入数组转换为一维数组的代码：

echo '<pre>';

$new_product_combinations = array();

foreach ($product_combinations as $k => $v) {
    $array = array();
    foreach ($v as $k1 => $v1) {
        $i = 1;
        foreach ($v1 as $k2 => $v2) {
            if (is_int($k2)) {
                $j = $i++;
                $array['product_colour_sizes_name_sizes' . $j] = $v2;
                $array['id' . $j] = $k2;
            } else {
                $array[$k2] = $v2;
            }
        }
        $array['product_colour_sizes_name_colours'] = $k1;
    }
    print_r($array); // output single combination
    $new_product_combinations[] = $array;
}

print_r($new_product_combinations);

希望这能对你有所帮助。

你能详细说明你想做什么吗？将所有这些数组合并为一个？如果是，在什么条件下？将多维数组转换为一维数组的术语是“展平”，即展平多维数组。您所需的结构没有意义，

product\u color\u size\u name\u sizes1

和其他类似的术语仍然需要在内部生成另一个数组
