将 foreach 分解为新数组

Question

我有 JSON API 看起来像这样的回复

Array
(
    [sections] => Array
        (
            [0] => Array
                (
                    [id] => 115000089967
                    [url] => xxxxx
                    [html_url] => ArticleHTML1
                    [category_id] => 204458828
                    [position] => 0
                    [sorting] => manual
                    [created_at] => 2016-12-19T14:56:23Z
                    [updated_at] => 2017-02-03T08:23:04Z
                    [name] => ArticleName1
                    [description] => 
                    [outdated] => 
                )

            [1] => Array
                (
                    [id] => 207077828
                    [url] => xxxxxx
                    [html_url] => ArticleHTML2
                    [category_id] => 204458828
                    [position] => 1
                    [sorting] => manual
                    [created_at] => 2016-11-14T09:28:30Z
                    [updated_at] => 2017-02-02T09:15:42Z
                    [name] => ArticleName2
                    [description] => 
                    [outdated] => 
                )
        )

    [page] => 1
    [per_page] => 30
    [page_count] => 1
    [sort_by] => position
    [sort_order] => asc
)

我已经用 foreach 成功地迭代了它，所以 return 看起来像这样：

ArticleName1 ArticleHTML1

ArticleName2 ArticleHTML2

所以我像这样分别取了 [name] 和 [html_url]:

$details1 = array('name');
$details2 = array('html_url');

foreach($sections['sections'] as $article) {
  foreach($details1 as $detail) {
    echo "$article[$detail] ";
  }
    foreach($details2 as $detail) {
    echo "$article[$detail]\n";
  }
}

但我接下来想要的是，该响应应该像这样分解为一个数组：

Array
(
    [0] => ArticleName1 ArticleHTML1
    [1] => ArticleName2 ArticleHTML2
)

我已经设法将它们分解为单独的数组：

foreach($sections['sections'] as $article) {
  foreach($details1 as $detail) {
    $name = "$article[$detail] ";
  }
    foreach($details2 as $detail) {
    $url = "$article[$detail]\n";
  }
  $string = $name . $url;
  $array = explode(' ', $string, 1);
  print_r($array);
}

但我只需要一个数组。

怎么样？我迷路了或者只是不明白，我什至接近了吗？

编辑

这里的问题是 JSON 转储非常大，我只需要很少的东西（名称和 url）。所以我在想我首先抓住整个东西，然后我只拿名字和 urls（就像第一个 foreach 所做的那样），然后把它们放回大批。因为从这些名称和 url 中我只需要最后 12 个键，并且从单个数组中获取它们很容易。

如果我能首先整理出我不想要的键，那将是完美的。那会解决我的问题。那么我就不需要一个新的数组等

你让这件事变得比它需要的要困难得多。这只是一个循环：

$array = array();
foreach ($sections['sections'] as $article) {
    $array[] = $article['name'] . ' ' . $article['html_url'];
}

将 foreach 分解为新数组

Explode foreach to new array

php

arrays

json

explode
