<?php

namespace App\Helpers;

use Illuminate\Database\Eloquent\Collection;

class StatusHelper
{
 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'));
        }
}

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

在你的app文件夹中创建一个helpers.php文件，并用composer加载它:

"autoload": {
    "classmap": [
        ...
    ],
    "psr-4": {
        "App\\": "app/"
    },
    "files": [
        "app/helpers.php" // <---- ADD THIS
    ]
},

然后把它添加到你的作曲家。Json文件，执行如下命令:

composer dump-autoload

如果您不喜欢将helpers.php文件保存在app目录中(因为它不是一个PSR-4命名空间类文件)，您可以做laravel.com网站所做的事情:将helpers.php存储在bootstrap目录中。记得在你的作曲器中设置它。json文件:

"files": [
    "bootstrap/helpers.php"
]

在app/Helper/Helpers.php中创建Helpers.php

namespace App\Helper
class Helpers
{


}

添加作曲家和作曲家更新

 "autoload": {
        "classmap": [
            "database/seeds",
            "database/factories",
            "database","app/Helper/Helpers.php"
        ],
        "psr-4": {
            "App\\": "app/"
        },
         "files": ["app/Helper/Helpers.php"]
    },

在控制器中使用

use App\Helper\Helpers

视图中使用 修改config->app.php文件

   'aliases' => [
    ...
    'Helpers'   => 'App\Helper\Helpers'
    ],

视图中调用

<?php echo Helpers::function_name();  ?>

在App/Helpers/中创建新文件examplehelper.php 然后加入作曲家。json文件

"autoload": { "classmap": [ "database"], "psr-4": { "App\\": "app/" },
"files": ["helpers/examplehelper.php" ]},

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!
