问题描述
我在 Laravel 中有以下集合:
I have the following collection in Laravel:
["TheNumbers":[{"episodeID":16818,"episodeNumber":100,"created_at":null,"updated_at":null},{"episodeID":16818,"episodeNumber":210,"created_at":"2017-02-20 21:30:38","updated_at":"2017-02-20 21:30:38"}]
如果我运行以下代码:
$TheEpisode->TheNumbers->pluck('episodeNumber');
我会得到以下结果:
[100,210]
我想保留每个号码的密钥，我该如何实现?
I would like to keep the keys for each number, how can I achieve this?
这是我的预期结果:
[{"episodeNumber":100},{"episodeNumber":210}]
PHILIS PETERS(改进)
TheEpisode->TheNumbers->reduce(function ($result, $episode) {
$episodeData = (collect())->put('episodeNumber', $episode['episodeNumber']);
$result[] = $episodeData;
return $result;
}));
推荐答案
尝试这样的事情，它应该可以使用 map...
Try something like this, it should work using map...
return $TheEpisode->TheNumbers->map(function ($episode) {
return ['episodeNumber' => $episode['episodeNumber']];
});
