我是新手使用PHP，但我一直遇到错误“尝试在数组上读取属性“id””。
这是我的视图list-monitors-get-show：
```html
<!-- ... （你的HTML代码） ... -->

public $state, $stateService, $schedules, $polyclinics = [];
// ... （你的其他代码） ...

<td wire:click="addSchedule({{ $polyclinic->id }})">

<td wire:click="addSchedule({{ $polyclinic['id'] }})">

when i try dd($this->schedules); [this schedule][2]
when i try to dd on function loadSchedule and addSchedule, i got schedules data. but when delete that dd. i got error "attempt to read property "id" on array"
i also tried to change
    <td wire:click="addSchedule({{ $polyclinic->id }})">
to
    <td wire:click="addSchedule({{ $polyclinic['id'] }})">
but i got error "cannot use object of type stdClass as array"
when I click 1 item on "Jenis Antrian"
[jenis antrian][3]
success to show Spesialis items
[specialis][4]
but when I click 1 item on specialise
[error](https://i.stack.imgur.com/xI0UU.png)
i want to show schedule data on that table

**得分**: 1
你正在以对象方式访问$polyclinic。
我认为你的意思是要以数组方式访问它，所以请在“addSchedule”方法内更新代码为`$polyclinic['id']`？
<details>
<summary>英文:</summary>
You&#39;re accessing $polyclinic as an object.
I believe you mean to access it as an array so update the code within the &quot;addSchedule&quot; method to `$polyclinic[&#39;id&#39;]` ?

同样的问题发生在我身上。我通过获取搜索结果并将其转换为数组来解决了这个问题。
在我的情况下，我收到了一个包含StdClass对象的数组，所以在发送整个对象集合之前，我使用了array_map来将对象转换为数组。这样就解决了问题。

The same problem happened to me. I solved it by taking the search result and converting it into an array.
In my case, I received an array with StdClass objects so before sending the entire collection of objects, I used array_map to cast the objects into arrays. It worked
