php - PHPは配列から配列を作成します

Question

私は2つのテーブルを持っていcontentますtheme. themeテーブルの行ごとに取得する必要がある行がいくつかありcontentます。これは、PDO と、LEFT JOIN. 出力配列は、テーマ ファイル (以下) の出現ごとに 1 つの配列を提供します。

contentID配列を再編成して、一致する各テーマ ファイルを含む配列内の配列を1 つの配列として取得するようにします。

アイデア$content=>'theme'['logo']は、一致するテーマ ファイルのいずれかの値を取得するようなものです。

これはどのように行われますか。

array(
       array (
            contentID => 1, 
            title => 'test', 
            subtitle = 'a description', 
            themeID => 1,
            theme_file => 'navigation'
        )

        array (
            contentID => 1, 
            title => 'test', 
            subtitle = 'a description', 
            themeID => 2,
            theme_file => 'logo'
        )
)

リクエストに応じて、追加のコードを追加しました。実際には、相互にネストしたい3つのテーブルがありますが、他の人に役立つ質問をするために、2のままにしました。これは、役立つ場合のmySQLクエリです。

SELECT * 
FROM content
LEFT JOIN content_theme ON content.contentID = content_theme.contentID
LEFT JOIN theme ON theme.themeID = content_theme.themeID
OR theme.default =1
LEFT JOIN theme_meta ON theme.themeID = theme_meta.themeID
WHERE content.contentID = 9
ORDER BY theme.default DESC 

contentしたがって、各行が一致するすべての行をネストしtheme、これらのtheme各行が一致するtheme_meta各行をネストすることが意図されています。

データベースからの生の出力:

    [0] => Array
        (
            [contentID] =>

このように配列をネストできます。

$aContent = array();
foreach($aRows AS $aRow){
    $aContent[$aRow['contentID']][] = array(
        'theme' => array(
            'themeID' => $aRow['themeID'],
            'themeType' => $aRow['theme_type'],
            'themeTitle' => $aRow['theme_title']
        ),
        'type' => 'page',
    );
}
