答

您可以使用map操作将日期重新格式化为给定格式:

You can use the map operation to reformat your date as your given format :

public function index() {
 
    $campaigns_dates = CampaignHistory::orderBy('created_at', 'ASC')
        ->pluck('created_at')
        ->map
        ->format('Y-m-d H:i:s');

    $campaigns_dates = json_decode($campaigns_dates);
    return $campaigns_dates;
}

替代解决方案:由于

Alternative Solution : There is an alternative solution with selectRaw() method, thanks to @OMR for provide this solution :

public function index() {
 
    $campaigns_dates = CampaignHistory::orderBy('created_at', 'ASC')
        ->selectRaw("DATE_FORMAT(created_at, '%Y-%m-%d %H:%i:%s') as formatted_date")
        ->pluck('formatted_date');

    $campaigns_dates = json_decode($campaigns_dates);
    return $campaigns_dates;
}
