我正在尝试组合从 2 个不同表生成的数组 - "文章"和"article_categories"。"article_categories"的输出为：
Array
(
[0] => Array
(
[id] => 0
[title] => local
)
[1] => Array
(
[id] => 1
[title] => politics
)
[2] => Array
(
[id] => 2
[title] => economics
)
)
函数代码为：
public function newsGetCategoryList() {
$result = $this->db->select('SELECT * FROM article_categories ORDER BY id');
return $result;
}
"文章"的输出是：
Array
(
[0] => Array
(
[id] => 0
[title] => Article 1
[content] => content
[category] => local
)
[1] => Array
(
[id] => 1
[title] => Article 2
[content] => content
[category] => local
)
[2] => Array
(
[id] => 2
[title] => Article 2
[content] => content
[category] => local
)
)
函数代码为：
public function newsGetCategoryArticles($category) {
$result = $this->db->select('SELECT * FROM articles WHERE category_id = :category', array('category' => $category));
return $result;
}
我需要将"articles"数组插入"article_categories"，因此输出变为：
Array
(
[0] => Array
(
[id] => 0
[title] => local
[articles] => Array
(
[0] => Array
(
[id] => 0
[title] => Article 1
[content] => content
[category] => local
)
[1] => Array
(
[id] => 1
[title] => Article 2
[content] => content
[category] => local
)
[2] => Array
(
[id] => 2
[title] => Article 2
[content] => content
[category] => local
)
)
)
[1] => Array
(
[id] => 1
[title] => politics
)
[2] => Array
(
[id] => 2
[title] => economics
)
)
换句话说，如果文章的类别值与类别的标题匹配，则文章应位于类别数组内。
我尝试在"article_categories"的 foreach 循环中应用 array_push，但我只为每个类别条目获得一个单独的数组，而不是整个数组。我不知道如何处理这个问题。
谢谢
自己找到了解决方案。不得不更改新闻获取类别列表（）
public function newsGetCategoryList() {
$array = $this->db->select('SELECT * FROM article_categories ORDER BY id');
$result = array();
foreach ($array as $value) {
$articles = $this->newsGetCategoryArticles($value['title']);
array_push($value, $articles);
$result[] = $value;
}
return $result;
}
