默认的created_at日期继续打印为 MySQL 格式：2015-06-12 09:01:26。我想以我自己的方式打印它，就像12/2/2017未来的其他格式一样。

1. Within your app/Httpdirectory, create a helpers.phpfile and add your functions.
2. Within composer.json, in the autoloadblock, add "files": ["app/Http/helpers.php"].
3. Run composer dump-autoload

1. 在您的app/Http目录中，创建一个helpers.php文件并添加您的函数。
2. 在 中composer.json，在autoload块中，添加"files": ["app/Http/helpers.php"]。
3. 跑 composer dump-autoload

That should do it. :)

那应该这样做。:)

Since your Helper method is static you could add your helper class to config/appalias just like a Facade, like so:

由于您的 Helper 方法是静态的，您可以config/app像 Facade 一样将您的 helper 类添加到别名，如下所示：

'aliases' => [
    //'dateHelper'=> 'App\Helpers\DateHelper', //for Laravel 5.0
    'dateHelper'=> App\Helpers\DateHelper::class, //for Laravel 5.1
] 

Then later in your view:

然后在你看来：

{{dateHelper::dateFormat1($user->created_at)}}

However, if you are also looking for a way to do this without a helper class. You may consider using Mutators and Appends in your model:

但是，如果您也在寻找一种没有帮助类的方法来做到这一点。您可以考虑在模型中使用 Mutators 和 Appends：

class User extends Model{
   protected $fillable = [
     'date'
   ];

   protected $appends = [
     'date_format_two'
   ];


   public function getDateAttribute($value){
        $dt = new DateTime($value);
        return $dt->format("m/d/y"); // 10/27/2014
   }

    //date
    public function getDateFormatTwoAttribute($value){
        $dt = new DateTime($value);
        return $this->attributes['date_format_two'] = $dt->format("m, d ,y"); // 10,27,2014
    }
} 

Later you can do

以后你可以做

$user = User::find(1);

{{$user->date}}; 
{{$user->date_format_two}};
