php artisan make:event <event-class> 

在这里，<event-class>应使用事件类的名称来代替。创建的类将被存储在 app\events 目录。

php artisan handler:event <handler-class> --event = <event-class> 

在这里，<event-class>应使用我们在步骤1来代替应，<handler-class> 创建事件类的名称使用处理程序类的名称来取代。新创建的处理程序类将被存储在app\handlers\events 目录。

现在，我们需要注册该事件在文件 - app\providers\eventserviceprovier.php。 此文件包含一个数组：$listen。在这个数组，我们需要事件类添加作为键以及事件处理程序类作为它的值。

最后一步是触发使用事件门面触发事伯。fire()方法由事件类的对象调用。事件可以触发如下 -

event::fire(<event class object>);

实例

php artisan make:controller createstudentcontroller 

app/http/controllers/createstudentcontroller.php

<?php
namespace app\http\controllers;
use illuminate\http\request;
use db;
use app\http\requests;
use app\http\controllers\controller;
use app\events\studentadded;
use event;

class createstudentcontroller extends controller {
   public function insertform(){
      return view('stud_add');
   }
   
   public function insert(request $request){
      $name = $request->input('stud_name');
      $age = $request->input('stud_age');
db::insert('insert into student (name,age) values(?, ?)',[$name, $age]);
      echo "record inserted successfully.<br/>";
      echo '<a href = "/event">click here</a> to go back.';
      //firing an event
      event::fire(new studentadded($name));
   }
}

php artisan make:event studentadded

app\events\studentadded.php

<?php
namespace app\events;
use app\events\event;
use illuminate\queue\serializesmodels;
use illuminate\contracts\broadcasting\shouldbroadcast;

class studentadded extends event {
   use serializesmodels;
   public $name;
  
   public function __construct($name) {
      $this->name = $name;
   }
   public function broadcaston() {
      return [];
   }
}

第9步 - 创建一个事件处理文件在 app\handlers\events\handlenewstudentadded.php，复制以下代码到该文件中。

app\handlers\events\handlenewstudentadded.php

<?php
namespace app\handlers\events;
use app\events\studentadded;
use illuminate\queue\interactswithqueue;
use illuminate\contracts\queue\shouldqueue;

class handlenewstudentadded {
   protected $name;
   
   public function __construct() {
      //
   }
   public function handle(studentadded $event) {
      $this->name = $event->name;
      echo "<br><u>new student added in database with name: </u>".$this->name;
   }
} 

第10步 - 现在，我们需要添加事件类和处理程序类存储在文件 - app\providers\eventserviceprovider.php

app\providers\eventserviceprovider.php

<?php
namespace app\providers;
use illuminate\contracts\events\dispatcher as dispatchercontract;
use illuminate\foundation\support\providers\eventserviceprovider as serviceprovider;

class eventserviceprovider extends serviceprovider {
   /**
   * the event listener mappings for the application.
   *
   * @var array
   */
   protected $listen = [
      'app\events\someevent' => [
         'app\listeners\eventlistener',
      ],
   
      'app\events\studentadded' => [
         'app\handlers\events\handlenewstudentadded',
      ],
   ];
   /**
   * register any other events for your application.
   *
   * @param \illuminate\contracts\events\dispatcher $events
   * @return void
   */
   public function boot(dispatchercontract $events) {
      parent::boot($events);
      //
   }
}

app/http/routes.php

route::get('event','createstudentcontroller@insertform');
route::post('addstudent','createstudentcontroller@insert');

http://localhost:8000/event

第14步 - 增加学生的姓名，然后点击“添加学生”按钮，将您重定向到下面的屏幕。看看灰色高亮行。 我们已经指定处理方法，在一个事件被触发执行handlenewstudentadded类的处理方法时添加此行。
