Question

我试图合并从2个不同的表格生成的数组 - ＆＃39;文章＆＃39;和＆＃39; article_categories＆＃39;。＆＃39; article_categories＆＃39;的输出是：

Array
(
[0] => Array
    (
        [id] => 0
        [title] => local
    )

[1] => Array
    (
        [id] => 1
        [title] => politics
    )

[2] => Array
    (
        [id] => 2
        [title] => economics
    )
)

功能代码是：

public function newsGetCategoryList() {
        $result = $this->db->select('SELECT * FROM article_categories ORDER BY id');   
        return $result;
}

＆＃39;文章的输出＆＃39;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
    )
)

功能代码是：

public function newsGetCategoryArticles($category) {
       $result = $this->db->select('SELECT * FROM articles WHERE category_id = :category', array('category' => $category));            
       return $result;
    }

我需要插入＆＃39;文章＆＃39;阵列成＆＃39; article_categories＆＃39;所以输出变为：

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，文章应该在类别数组中，如果文章＆＃39;类别值与类别标题匹配。

我尝试在foreach循环中应用array_push＆＃39; article_categories＆＃39;但是我只为每个类别条目获取一个单独的数组，而不是整个数组。我不知道如何处理这个问题。

自己找到解决方案。不得不改变newsGetCategoryList（）

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;
    }

使用公共值将两个表中的两个数组合并为一个数组
