数组分组-如何构建API响应

Question

好的，问题是出价奇怪，因为我不确定如何用简短的标题很好地解释它。

所以这是我的想法（只是让它更有意义）

我搞砸了spotify api，并试图保存我的所有歌曲（将它们导出），因为我有很多歌曲，如果Spotify弄乱了某些东西而一切变坏了，我仍然会列出所有我的歌曲。

所以这是我的问题。

我设法获得了所有歌曲和Artits的名字。 Prbolem是我有“更多”的艺术家然后有歌曲，因为有1个或更多的人在唱歌（功能）

这是一些代码，可能可以解决问题...

 $tracksData = $this->getAllPlaylistTracksData('PLAYLISTID');

        var_dump($tracksData);

        $allTracksName = [];

        foreach ($tracksData as $trackData) {
            $artistsData = $trackData->track->artists;

            var_dump($artistsData);

            $allTracksName[] = $trackData->track->name;

        }

 return $allTracksName;

这是两个转储输出：

如您所知，第二个转储是我的播放列表1：1

现在我的问题是我不确定如何对它们进行分组，是的，我尝试像这样遍历它们

foreach ($artistsData as $artistData) {
                $allArtistsName[] = $artistData->name;
            }

但这仅给我留下了两个庞大的数组，它们的大小各不相同，因为除了歌曲外还有“更多”的艺术作品。

有谁知道我该如何解决这个问题？

编辑：

我想要这样的东西

0 => [
songName => i
Artists = > x y z
]

Answer 1

您可以在var_dump中看到在他的歌曲数组中找到了每个歌手-因此您可以在songs数组中添加另一个循环并提取每首歌曲的歌手列表：

 $tracksData = $this->getAllPlaylistTracksData('PLAYLISTID');

 $songs = [];

 foreach ($tracksData as $trackData) {
     $artistsNamesForSong = []; // init new artists array for each song
     foreach($trackData->track->artists as $artist) {
         $artistsNamesForSong[] = $artist->name;
     }

     $songs[] = ["songName" => , "Artists" => $artistsNamesForSong];
 }

 return $songs;
