php - 将数组传递给侦听器并获取更新的数组

Question

我正在将一个数组传递给一个事件，并且我正在更新侦听器中的数组。但我没有在事件发生后取回更新的数组。

这是我调用事件的地方：

$roles_permissions = ["val1"];
event(new SeedingRolesPermissions($roles_permissions));
var_dump($roles_permissions);

这是事件类的代码。我只是使用构造函数来设置事件的 roles_permissions 数组。我也尝试通过引用传递数组，但没有帮助。

<?php

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;

class SeedingRolesPermissions
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $roles_permissions;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($roles_permissions)
    {
        $this->roles_permissions = $roles_permissions;
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new PrivateChannel('channel-name');
    }
}

这是事件的侦听器：

<?php

namespace Modules\Sales\Listeners;

use App\Events\SeedingRolesPermissions;
use Log;

class AddRolesPermissions
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        
    }

    
    /**
     * Handle the event.
     *
     * @param  SeedingRolesPermissions  $event
     * @return void
     */
    public function handle(SeedingRolesPermissions $event)
    {
        $event->roles_permissions[] =  ["val2"];
    }
}

任何帮助将不胜感激！
