# Anonymous Event Broadcasting

11.5 新增了 anonymous event，即如果確定這一個 event 就只有當下會用到，它不會也不該在其他地方被使用，那就可以使用 anonymous event

直接使用 send()

<?php
Broadcast::on('orders.'.$order->id)->send();

這會 dispatch 一個 anonymous event，前端會收到如下資料

{
  "event": "AnonymousEvent",
  "data": "[]",
  "channel": "orders.1"
}

也可以使用 as & with 來定義 event name & data

<?php
Broadcast::on('orders.'.$order->id)
    ->as('OrderPlaced')
    ->with($order)
    ->send();

前端會收到如下資料

{
  "event": "OrderPlaced",
  "data": "{ id: 1, total: 100 }",
  "channel": "orders.1"
}

可以使用 private() or present() 來 dispatch anonymous event 到 private or present channel

<?php
Broadcast::private('orders.'.$order->id)->send();
Broadcast::presence('channels.'.$channel->id)->send();

send() 會將 event dispatch 到 Queue，如果想要立即 dispatch event，可以使用 sendNow()

<?php
Broadcast::on('orders.'.$order->id)->sendNow();

可以使用 toOthers()，只將 event dispatch 給 authenticated user 之外的人

<?php
Broadcast::on('orders.'.$order->id)
    ->toOthers()
    ->send();

url()->query('products', ['sort' => '-name']);
 
// http://localhost/products?columns[0]=name&columns[1]=price&columns[2]=quantity
url()->query('products', ['columns' => ['name', 'price', 'quantity']]);
 
// Overiding parameters:
// http://localhost/products?sort=-price
url()->query('products?sort=-name', ['sort' => '-price']);
 
// Appending parameters
// http://localhost/products?sort=-name&search=samsung
url()->query('products?sort=-name', ['search' => 'samsung']);
