Question

我有阵列：

$array = Array(
      [0] => Array(
                  [Branch] => 'Toyota',
                  [Country] => 'Jpn',
                  [id] => 'jp01'
      )
      [1] => Array(
                  [Branch] => 'Nissan',
                  [Country] => 'Jpn',
                  [id] => 'jp05'
      )
      [2] => Array(
                  [Branch] => 'Honda',
                  [Country] => 'Jpn',
                  [id] => 'jp20'
      ) )

我想做的是：
1 - 将密钥 Branch 更改为 Brand ，但不将其移至最后或数组。
2 - 将所有值更新为关键国家/地区，将 Jpn 更改为 Japan

结果应该是这样的：

$array = Array(
      [0] => Array(
                  [Brand] => 'Toyota',
                  [Country] => 'Japan',
                  [id] => 'jp01'
      )
      [1] => Array(
                  [Brand] => 'Nissan',
                  [Country] => 'Japan',
                  [id] => 'jp05'
      )
      [2] => Array(
                  [Brand] => 'Honda',
                  [Country] => 'Japan',
                  [id] => 'jp20'
      ) )

我非常感谢你的帮助。

Answer 1

$newArray = array();
foreach($array as $ar){
    $newArray[] = array(
       'Brand' => $ar['Branch'],
       'Country' => 'Japan',
       'id' => $ar['id']
    )
}
$array = $newArray;

Answer 2

foreach($array as &$item) {
    $branch = $item['Branch'];
    array_unshift($item, array("Brand"=>$branch));
    unset($item['Branch']);
    $item['Country'] = 'Japan'; 
}

没有测试过..

Answer 3

TRY：

<?php
foreach($array as $key => $data)
{
$data['Brand'] = $data['Branch'];
$data['Country'] = 'Japan';
unset($data['Branch']);
$array[$key] = $data;
}
?>

Answer 4

这应该这样做。

<?php
foreach($array as $k => $v) {
  $array[$k]['Brand'] = $array[$k]['Branch'];
  unset($array[$k]['Branch'];
  if($array[$k]['Country'] == 'Jpn') {
    $array[$k]['Country'] = 'Japan';
  }
}
?>

可能也有聪明的数组函数可以做到，但这将完成工作。

Answer 5

foreach($array as $key => $subArray){
    foreach($subArray as $subkey => $value)
        if($value === 'Jpn') $subArray[$subkey] = 'Japan';
    $array[$key] = $subArray;
}


foreach($array as $key => $subArray){
    $subArray = array_flip($subArray);
    foreach($subArray as $subkey => $value)
        if($value === 'Branch') $subArray[$subkey] = 'Brand';
    $subArray = array_flip($subArray);
    $array[$key] = $subArray;
}

输出：

Array ( [0] => Array ( [Brand] => Toyota [Country] => Japan [id] => jp01 ) [1] => Array ( [Brand] => Nissan [Country] => Japan [id] => jp05 ) [2] => Array ( [Brand] => Honda [Country] => Japan [id] => jp20 ) )
