PHP按时间顺序将存储数组中的值设置为嵌套的foreach循环

我有一个

$data

数组，它包含4个索引。我在这里试图实现的是将

$data

数组中的值设置为嵌套的

foreach

循环，但在执行结束时，它存储最后一个索引的值

<?php
// Some IDs.
$nids = [12, 56, 55, 59, 83];

$data = [
  'Ludo Bagman' => 'Head of the Department of Magical Games and Sports within the Ministry of Magic.',
  'Bathilda Bagshot' => 'Author of A History of Magic, and the great aunt of Gellert Grindelwald.',
  'Katie Bell' => 'Gryffindor Quidditch Chaser one year above Harry Potter. Member of Dumbledore\'s Army.',
  'Cuthbert Binns' => 'Ghost, History of Magic professor.',
];

foreach ($nids as $nid) {
  $term = \Drupal::entityTypeManager()->getStorage('node')->load($nid);
  $paragraphs = $term->get('field_paragraphs')->referencedEntities();

  foreach ($paragraphs as $key => $paragraph) {

    if (in_array($key, [0, 1, 3, 6])) {

      // Here, only the last element from the $data array is stored, i.e. value
      // of `Cuthbert Binns`, whereas each of the above `$key` should take the
      // value from the `$data` array in chronological order.
      foreach ($data as $title) {
        $paragraph->get('field_links')->setValue([
          'title' => $title,
        ]);
      }
      $paragraph->save();
    }
  }
}

但事实是：

$paragraph[0]['field_links']['title']; // Ghost, History of Magic professor.
$paragraph[1]['field_links']['title']; // Ghost, History of Magic professor.
$paragraph[3]['field_links']['title']; // Ghost, History of Magic professor.
$paragraph[6]['field_links']['title']; // Ghost, History of Magic professor.

如果要将

标题设置为
键

$data = [
  'Ludo Bagman' => 'Head of the Department of Magical Games and Sports within the Ministry of Magic.',
  'Bathilda Bagshot' => 'Author of A History of Magic, and the great aunt of Gellert Grindelwald.',
  'Katie Bell' => 'Gryffindor Quidditch Chaser one year above Harry Potter. Member of Dumbledore\'s Army.',
  'Cuthbert Binns' => 'Ghost, History of Magic professor.',
];
$keys = [0,1,3,6];
$keyedData = array_combine($keys, $data);

// ...

foreach ($paragraphs as $key => $paragraph) {
    if (in_array($key, $keys)) {
        $paragraph->get('field_links')->setValue([
          'title' => $keyedData[$key],
        ]);
        
        $paragraph->save();
    }
}

如果您将来需要这些名称：

$keyedNames = array_combine($keys, array_keys($data));

参考资料



我认为这是因为您重写了循环中的值，然后它保存了数组的最后一个索引。如果可能，请粘贴您的预期输出。您是否尝试将
Ludo Bagman
的内容设置为
$key
0
和
Bathilda Bagshot
设置为
1
等？您应该澄清您的问题，不清楚您试图实现什么更新了问题的更多信息，现在应该有意义了。您的解决方案有意义，但在我尝试后，显示了以下错误：
[warning]array_combine（）：两个参数的元素数应该相等
@rishikulshreshta Yes，对于每个元素
$data
，您都需要在
$keys
中输入一个键。这是一个完美的答案！数据最初在我的位置有点不正确，因此得到了错误。谢谢你的提醒。
$keyedNames = array_combine($keys, array_keys($data));
