转换PHP＆QUOT;分组＆QUOT;阵列＆QUOT;分段＆QUOT;排列 [英] Convert PHP "grouped" array to "segmented" array

问题描述

尝试将分组多维数组转换为分段多维数组。不知道如何解释呢准确，所以希望这些的print_r 业绩好解释。

Trying to convert a "grouped" multidimensional array to a "segmented" multidimensional array. Not sure how to explain it exactly so hopefully these print_r results explain it better.

当前阵列

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

    [item_id] => Array
        (
            [0] => RR332
            [1] => FF586
            [2] => QW865
        )

    [item_name] => Array
        (
            [0] => Widget 1
            [1] => Widget 2
            [2] => Widget 3
        )

    [price] => Array
        (
            [0] => 1.00
            [1] => 1.50
            [2] => 1.50
        )

)

通缉阵列

Array
(
    [0] => Array
        (
            [qty] => 1
            [item_id] => RR332
            [item_name] => Widget 1
            [price] => 1.00
        )

    [1] => Array
        (
            [qty] => 1
            [item_id] => FF586
            [item_name] => Widget 2
            [price] => 1.50
        )

    [2] => Array
        (
            [qty] => 1
            [item_id] => QW865
            [item_name] => Widget 3
            [price] => 1.50
        )

)

这似乎是它应该是一个简单的任务，但我一直没能还没有破解它。

This seems like it should be a simple task but I haven't been able to crack it yet.

我想preferably喜欢通过的当前阵列的创造的通缉阵列循环的如果可能的话。

I would preferably like to loop through the Current Array to create the Wanted Array if possible.

任何帮助是极大AP preciated！

Any help is greatly appreciated!

感谢。

推荐答案

我认为这将做的工作适合你，虽然我不具备良好的数据集，以测试对。

I think this will do the job for you, though I don't have a good data set to test against.

$wanted_array = array();
// Iterate over the outer array to get the text keys & inner arrays
foreach ($current_array as $txtkey=>$arr) {
  // Iterate over each inner array to get the numeric key
  foreach ($arr as $numkey=>$val) {
    // Set a numeric key pointing to a new array 
    // onto the new outer array if it isn't already there
    if (!isset($wanted_array[$numkey])) $wanted_array[$numkey] = array();

    // Swap the keys of the outer and inner arrays.
    $wanted_array[$numkey][$txtkey] = $val;
  }
}

更新：从@ hakre的回答使用测试序列，在这里它是在实践中：

$current_array = array(
  'qty' => array(
    0 => 1,
    1 => 1,
    2 => 1
  ),
  'item_id' => array(
    0 => 'RR332',
    1 => 'FF586',
    2 => 'QW865'
  ),
  'item_name' => array(
    0 => 'Widget 1',
    1 => 'Widget 2',
    2 => 'Widget 3'
  ),
  'price' => array(
    0 => '1.00',
    1 => '1.50',
    2 => '1.50'
  )
);
// Output:
Array
(
    [0] => Array
        (
            [qty] => 1
            [item_id] => RR332
            [item_name] => Widget 1
            [price] => 1.00
        )

    [1] => Array
        (
            [qty] => 1
            [item_id] => FF586
            [item_name] => Widget 2
            [price] => 1.50
        )

    [2] => Array
        (
            [qty] => 1
            [item_id] => QW865
            [item_name] => Widget 3
            [price] => 1.50
        )

)
