创建自定义助手目录: 首先在app目录中创建Helpers目录。 创建hlper类定义: 现在让我们创建一个简单的辅助函数，它将连接两个字符串。在/app/Helpers/MyFuncs.php中创建一个新文件MyFuncs.php

<?php

namespace App\Helpers;

class MyFuncs {

    public static function full_name($first_name,$last_name) {
        return $first_name . ', '. $last_name;   
    }
}

名称空间的应用程序\助手;在App namespace下定义了Helpers命名空间。 类MyFuncs{…}定义了帮助类MyFuncs。 公共静态函数full_name($first_name，$last_name){…}定义了一个静态函数，它接受两个字符串形参并返回一个连接的字符串

帮工服务提供类

服务提供者用于自动加载类。我们需要定义一个服务提供者，它将加载/app/Helpers目录下的所有helper类。

执行以下artisan命令:

php工匠使:提供者HelperServiceProvider

该文件将创建在/app/Providers/HelperServiceProvider.php中

Open /app/Providers/HelperServiceProvider.php

添加如下代码:

<?php 

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class HelperServiceProvider extends ServiceProvider {

   /**
    * Bootstrap the application services.
    *
    * @return void
    */
   public function boot()
   {
      //
   }

   /**
    * Register the application services.
    *
    * @return void
    */
   public function register()
   {
        foreach (glob(app_path().'/Helpers/*.php') as $filename){
            require_once($filename);
        }
   }
}

在这里,

namespace App\Providers; defines the namespace provider
use Illuminate\Support\ServiceProvider; imports the ServiceProvider class namespace
class HelperServiceProvider extends ServiceProvider {…} defines a class HelperServiceProvider that extends the ServiceProvider class
public function boot(){…} bootstraps the application service
public function register(){…} is the function that loads the helpers
foreach (glob(app_path().'/Helpers/*.php') as $filename){…} loops through all the files in /app/Helpers directory and loads them.

现在我们需要注册HelperServiceProvider并为我们的助手创建一个别名。

打开/config/app.php文件

找到providers数组变量

添加以下行

App\Providers\HelperServiceProvider::class,

定位aliases数组变量

添加以下行

'MyFuncs' => App\Helpers\MyFuncs::class,

保存更改 使用我们的自定义助手

我们将创建一个调用自定义帮助函数Open /app/routes.php的路由

添加以下路由定义

Route::get('/func', function () {
    return MyFuncs::full_name("John","Doe");
});

在这里,

return MyFuncs::full_name("John","Doe"); calls the static function full_name in MyFuncs class

我知道现在回答这个问题已经很晚了，但是，这个问题每天都发生在所有初级开发人员身上，所以对于直接步骤，请执行以下步骤:

**将你的helper函数分组到类中(使用刀片中的函数只是使它们静态)，并将所有类放在配置Laravel文件夹app.php别名

'aliases' => [
  "YourClassName" => App\Support\YourClassName,
]

现在你可以在刀片和控制器上使用所有的静态函数了。

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

我使用的另一种方法是: 1)在应用程序\FolderName\fileName.php中创建一个文件，并在其中包含以下代码

<?php
namespace App\library
{
 class hrapplication{
  public static function libData(){
   return "Data";
  }
 }
}
?>

2)之后在我们的刀片

 $FmyFunctions = new \App\FolderName\classsName;
  echo $is_ok = ($FmyFunctions->libData());

就是这样。这是可行的

下面是我创建的一个bash shell脚本，用于快速制作Laravel 5外观。

在Laravel 5安装目录中运行这个程序。

这样叫它:

make_facade.sh -f <facade_name> -n '<namespace_prefix>'

例子:

make_facade.sh -f helper -n 'App\MyApp'

如果你运行这个例子，它会在“your_laravel_installation_dir/app/MyApp”下创建目录Facades和Providers。

它将创建以下3个文件，并将它们输出到屏幕上:

./app/MyApp/Facades/Helper.php
./app/MyApp/Facades/HelperFacade.php
./app/MyApp/Providers/HelperServiceProvider.php

完成后，它将显示类似于下面的消息:

===========================
    Finished
===========================

Add these lines to config/app.php:
----------------------------------
Providers: App\MyApp\Providers\HelperServiceProvider,
Alias: 'Helper' => 'App\MyApp\Facades\HelperFacade',

更新'config/app.php'中的Providers和Alias列表

运行composer -o dumpautoload

"./app/MyApp/Facades/Helper.php"最初看起来是这样的:

<?php

namespace App\MyApp\Facades;


class Helper
{
    //
}

现在只需在“。/app/MyApp/Facades/Helper.php”中添加方法。

下面是“。/app/MyApp/Facades/Helper.php”在我添加了一个Helper函数后的样子。

<?php

namespace App\MyApp\Facades;

use Request;

class Helper
{
    public function isActive($pattern = null, $include_class = false)
    {
        return ((Request::is($pattern)) ? (($include_class) ? 'class="active"' : 'active' ) : '');
    }
}

This is how it would be called:
===============================

{!!  Helper::isActive('help', true) !!}

这个函数需要一个模式，并且可以接受可选的第二个布尔参数。

如果当前URL匹配传递给它的模式，它将输出'active'(或者'class="active"'，如果你添加'true'作为函数调用的第二个参数)。

我用它来突出显示激活的菜单。

下面是我的脚本的源代码。我希望你觉得它有用，如果你有任何问题请告诉我。
