我在 Laravel 應(yīng)用程序中有一個(gè)數(shù)組，我想在 Laravel 偵聽(tīng)器中修改它。PHP 默認(rèn)按值傳遞一個(gè)數(shù)組，但是，Laravel 事件及其偵聽(tīng)器的工作方式我無(wú)法修改原始變量。有沒(méi)有比我在下面做的更好的方法？從中觸發(fā)事件的模型。型號(hào)：Event.phpnamespace Vendor\Package\Modelsuse Vendor\Package\Events\PageNodeArrayAfter;use Event;class Page{   public function toArray()   {      $data = [];       // do something with the data.       Event::fire(new PageNodeToArrayAfter($data))      // The data should be modified by a listener when I use it here.   }}事件：PageNodeToArrayAfter.phpnamespace Vendor\Package\Events;class PageNodeToArrayAfter{    /**     * Props to be sent to the view     * @var array $data     */    protected $data = [];    /**     * @param array $data     *      */    public function __construct(array &$data)    {        $this->data = $data;    }    public function getData()    {        return $this->data;    }}監(jiān)聽(tīng)器：FlashMessagesListner.phpnamespace Vendor\Package\Listeners;class FlashMessagesListner{    protected $data = [];    public function handle(PageNodeToArrayAfter $event)    {       $this->data = $event->getData();       // The problem here is the $data is no logner a reference here.     }}
