如何将多维数组合并为单个数组

Question

我有一个数组POST，看起来像这样

Array
(
[ponumber] => 111111
[man_part_number] => Array
    (
        [0] => 11C2555
        [1] => 11C2555
        [2] => 11C2555
        [3] => 11C2555
    )

[model] => Array
    (
        [0] => FORMS PRINTER 2500 SERIES
        [1] => FORMS PRINTER 2500 SERIES
        [2] => FORMS PRINTER 2500 SERIES
        [3] => FORMS PRINTER 2500 SERIES
    )

[damaged] => Array
    (
        [0] => 0
        [1] => 0
        [2] => 0
        [3] => 0
    )

[serial_number] => Array
    (
        [0] => CNCQ202070
        [1] => CNCQ210800
        [2] => MY5203B1KQ
        [3] => CN1863Q0PQ
    )

[skid] => Array
    (
        [0] => 1
        [1] => 2
        [2] => 3
        [3] => 4
    )

[submit] => Attach this serial number list to PO#111111
)

我需要将数组合并到

Array
(
[man_part_number] => Array
    (
        [0] = > 11C2555
    )
[model] => Array
    (
        [0] => FORMS PRINTER 2500 SERIES
    )
[damaged] => Array
    (
        [0] => 0
    )
[serial_number] => Array
    (
        [0] => CNCQ202070
    )
[skid] => Array
    (
        [0] => 1
    )
[ponumber] => Array
    (
        [0] => 111111
    }
}

依此类推，因此所有的数组也是1、2和3的组合，但每个数组都需要加上ponumber，并且对所有4个数组都是相同的。

Answer 1

$array = array_map('current', $array[0]);

Answer 2

您可以使用MultipleIterator

$mi = new MultipleIterator(MultipleIterator::MIT_NEED_ALL|MultipleIterator::MIT_KEYS_ASSOC);
$mi->attachIterator(new ArrayIterator($data['man_part_number']),"man_part_number");
$mi->attachIterator(new ArrayIterator($data['model']),"model");
$mi->attachIterator(new ArrayIterator($data['damaged']),"damaged");
$mi->attachIterator(new ArrayIterator($data['serial_number']),"serial_number");
$mi->attachIterator(new ArrayIterator($data['skid']),"skid");

echo "<pre>";
foreach ($mi as $member) {
    print_r($member);
}

Output

Array
(
    [man_part_number] => 11C2555
    [model] => FORMS PRINTER 2500 SERIES
    [damaged] => 0
    [serial_number] => CNCQ202070
    [skid] => 1
)
Array
(
    [man_part_number] => 11C2555
    [model] => FORMS PRINTER 2500 SERIES
    [damaged] => 0
    [serial_number] => CNCQ210800
    [skid] => 2
)
Array
(
    [man_part_number] => 11C2555
    [model] => FORMS PRINTER 2500 SERIES
    [damaged] => 0
    [serial_number] => MY5203B1KQ
    [skid] => 3
)
Array
(
    [man_part_number] => 11C2555
    [model] => FORMS PRINTER 2500 SERIES
    [damaged] => 0
    [serial_number] => CN1863Q0PQ
    [skid] => 4
)
