我是 Laravel 的初学者。我在我的项目中使用 Laravel 5.8。
我有这个代码：
$userPromotionDays = $user->premiumDate; // 2019.08.28
$daysToAdd = 5
如何将 $userPromotionDays 添加到 $daysToAdd （在 Laravel/Carbon 中）？
我在 Laravel 5.8 中有项目。我想将其更新到 6.0。如何将我的项目更新到版本 6？

我有这个架构：
Schema::create('user_login_histories', function (Blueprint $table) {
$table->bigIncrements('id');
$table->bigInteger('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
$table->dateTime('date_time');
$table->ipAddress('ip');
$table->engine = "InnoDB";
$table->charset = 'utf8mb4';
$table->collation = 'utf8mb4_unicode_ci';
});
和我的模型：
class UserLoginHistory extends Model
{
protected $quarded = ['id'];
public $timestamps = false;
protected $fillable = ['user_id', 'date_time', 'ip'];
public function user()
{
return $this->belongsTo('App\User');
}
// Show User login history
public function scopeHistory()
{
//return $this->hasMany('App\UserLoginHistory');
return $this->hasMany('App\UserLoginHistory', 'user_id', 'id');
}
}
我想通过此功能显示用户历史记录：
public function getLoginAdminHistory(int $idAdmin)
{
return UserLoginHistory::history()->orderBy('id', 'desc')->paginate(25);
}
但这不起作用。
我怎样才能解决这个问题？
