{
 protected static $_status = [
        1=> [
            'value' => 1,
            'displayName' => 'Active',
        ],
        2 => [
            'value' => 2,
            'displayName' => 'Inactive',
        ],
        3 => [
            'value' => 3,
            'displayName' => 'Delete',
        ],

    ];

     public static function getStatusesList()
    {
        $status = (new Collection(self::$_status))->pluck('displayName', 'value')->toArray();


        return $status;
    }
}

用于控制器和任何视图文件

use App\Helpers\StatusHelper;

class ExampleController extends Controller
{
        public function index()
        {
            $statusList = StatusHelper::getStatusesList();

            return view('example.index', compact('statusList'));
        }
}

我最初的想法是作曲家的自动加载，但它对我来说不太像Laravel 5。L5大量使用了服务提供者，它们引导你的应用程序。

首先，我在我的应用程序目录中创建了一个名为Helpers的文件夹。然后在Helpers文件夹中，我为我想添加的功能添加了文件。在一个文件夹中放置多个文件可以避免一个大文件变得太长而难以管理。

接下来，我通过运行artisan命令创建了一个HelperServiceProvider.php:

artisan make:provider HelperServiceProvider

在register方法中，我添加了这个代码片段

public function register()
{
    foreach (glob(app_path().'/Helpers/*.php') as $filename){
        require_once($filename);
    }
}

最后，在config/app.php的providers数组中注册服务提供者

'providers' => [
    'App\Providers\HelperServiceProvider',
]

现在，您的Helpers目录中的任何文件都已加载，并准备使用。

There are a lot of good options here, but if my answer works for you, I went ahead and made a package for including helpers this way. You can either use the package for inspiration or feel free to download it with Composer as well. It has some built in helpers that I use often (but which are all inactive by default) and allows you to make your own custom helpers with a simple Artisan generator. It also addresses the suggestion one responder had of using a mapper and allows you to explicitly define the custom helpers to load, or by default, automatically load all PHP files in your helper directory. Feedback and PRs are much appreciated!

composer require browner12/helpers

Github：布朗纳12/助手

在dir bootstrap\autoload.php中

require __DIR__.'/../vendor/autoload.php';
require __DIR__.'/../app/Helpers/function.php'; //add

添加这个文件

app\Helpers\function.php

首先在App\Helpers\Helper.php中创建你的Helper文件/类 就像:

<?php

namespace App\Helpers;

class Helper {

    // Your customer public function
}

然后在Composer.json中定义它 在交通量 然后运行composer dump-autoload

Laravel 5中的自定义类，简单的方法

这个答案适用于Laravel中的一般自定义类。有关更多Blade的具体答案，请参阅Laravel 5中的自定义Blade指令。

步骤1:创建您的Helpers(或其他自定义类)文件，并给它一个匹配的名称空间。编写你的类和方法:

<?php // Code within app\Helpers\Helper.php

namespace App\Helpers;

class Helper
{
    public static function shout(string $string)
    {
        return strtoupper($string);
    }
}

步骤2:创建别名:

<?php // Code within config/app.php

    'aliases' => [
     ...
        'Helper' => App\Helpers\Helper::class,
     ...

步骤3:在项目根目录下运行composer dump-autoload

第四步:在你的Blade模板中使用它:

<!-- Code within resources/views/template.blade.php -->

{!! Helper::shout('this is how to use autoloading correctly!!') !!}

额外学分:在你的Laravel应用程序的任何地方使用这个类:

<?php // Code within app/Http/Controllers/SomeController.php

namespace App\Http\Controllers;

use Helper;

class SomeController extends Controller
{

    public function __construct()
    {
        Helper::shout('now i\'m using my helper class in a controller!!');
    }
    ...
