如何使用 laravel 的集合访问对象？

Question

我有一个模块，我需要在数据库中插入所有每个数组对象的值，但是今天当我尝试转储对象时遇到问题，将对象放入数组中，它说尝试读取属性“客户”大批。目前我使用 laravel 我的后端

错误：

消息：“尝试读取数组上的属性“客户””，异常：“ErrorException

目标：获取每个对象。

转储：

$rows = collect($request->value);

    $collection = $rows->map(function ($item) {


        dd($item['customer']);
       
    });

我的请求负载：

Answer 1

问题是实际需要的数据在$request->value 中。正如错误所说，它的数组不是对象的集合。所以我认为应该是

$rows = collect($request->value);

    $collection = $rows->map(function ($item) {

        
        dd($item['customer']);
       
});

或者你可以试试

  $collection = $rows->map(function ((object)$item) {
    
            
            dd($item->customer);
           
    });
