Question

我在php中有一个像这样的数组：

[
    'gudang' => 'A'
    'blok' => '2'
    0 => [
        'coil_no' => 'DNA07X1C519081726A'
        'urut' => '28204'
        'lokasi_terakhir' => '411'
    ]
    1 => [
        'coil_no' => 'DNA07X1A518081712A'
        'urut' => '28205'
        'lokasi_terakhir' => '211'
    ]
    2 => [
        'coil_no' => 'DNA07X1A420081707A'
        'urut' => '28206'
        'lokasi_terakhir' => '311'
    ]
]

我需要将concat元素gudang，barang添加到具有元素lokasi_terakhir的另一个元素，即元素tipe。我需要这样：

[
    0 => [
        'coil_no' => 'DNA07X1C519081726A'
        'urut' => '28204'
        'lokasi_terakhir' => 'A2411'
    ]
    1 => [
        'coil_no' => 'DNA07X1A518081712A'
        'urut' => '28205'
        'lokasi_terakhir' => 'A2211'
    ]
    2 => [
        'coil_no' => 'DNA07X1A420081707A'
        'urut' => '28206'
        'lokasi_terakhir' => 'A2311'
    ]
]

我需要删除gudang，blok，然后连接到每个lokasi_terakhir元素。请指教。

Answer 1

尝试使用array_map：

$input = [
    0 => [
        'coil_no' => 'DNA07X1C519081726A'
        'urut' => '28204'
        'lokasi_terakhir' => '411'
    ]
    1 => [
        'coil_no' => 'DNA07X1A518081712A'
        'urut' => '28205'
        'lokasi_terakhir' => '211'
    ]
    2 => [
        'coil_no' => 'DNA07X1A420081707A'
        'urut' => '28206'
        'lokasi_terakhir' => '311'
    ]
];

$gudang = 'A';
$blok = 2;

$output = array_map(function(&$value) use ($gudang, $blok) {
    $value['lokasi_terakhir'] = $gudang.$blok.$value['lokasi_terakhir'];
}, $input);

Answer 2

请尝试

$gudang = $array['gudang'];
$blok = $array['blok'];
foreach($array as $key =>$val){
   $array['lokasi_terakhir'] = $gudang.$blok.$val['lokasi_terakhir'];
}
print_r($array);

Answer 3

试试这个：

$new_arr = [];
$str = $arr['gudang'] . $arr['blok'];
for($i = 0; $i < count($arr)-2; $i++) {
    $new_arr[$i] = $arr[$i];
    $new_arr[$i]['lokasi_terakhir'] = $str.$arr[$i]['lokasi_terakhir'];
}

print_r($new_arr);

Answer 4

$array1 = [
    'gudang' => 'A',
    'blok' => '2',
    0 => [
        'coil_no' => 'DNA07X1C519081726A',
        'urut' => '28204',
        'lokasi_terakhir' => '411'
    ],
    1 => [
        'coil_no' => 'DNA07X1A518081712A',
        'urut' => '28205',
        'lokasi_terakhir' => '211'
    ],
    2 => [
        'coil_no' => 'DNA07X1A420081707A',
        'urut' => '28206',
        'lokasi_terakhir' => '311'
    ]
];
$length = count($array1);
$array2 = array_splice($array1, 2, $length);
echo json_encode($array2);
