将 foreach 分解为新数组

Question

我有类似这样的 JSON API 响应

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                    [outdated] =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                    [outdated] =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
)

我已经成功地用foreach迭代了这个，所以返回看起来像这样：

ArticleName1 文章HTML1

ArticleName2 文章HTML2

所以我像这样从每一个中提取 [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，该响应应该分解为一个这样的数组：

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

我已经设法将它们分解为单个数组：

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）。所以我想我首先抓住整个东西，然后我只取名字和网址（就像第一个 foreach 正在做的那样），然后把它们放回数组。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会很容易。

如果我能首先整理出我不想要的钥匙，那将是完美的。那将解决我的问题。然后我就不需要新数组等了。

你让这件事变得比需要的困难得多。这只是一个循环：

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