【问题讨论】：

使用这个jsonviewer.stack.hu并正确检查你的数据然后通过`key`$data['key']['key2']....['markets']获取数据
你能举个例子吗
你能把你的数据发送为没有图片的代码格式，那么我可以
我更新了 json 请帮忙

【解决方案1】：

你试试这个

$markets = []; $products = [];
foreach($yourdata as $key => $data){

if(isset($data['events'][0]['markets']))
 $markets[$key][] = $data['events'][0]['markets'];

 //if you want get only one data insight markets in 0 
 // then use $markets[$key][] = $data['events'][0]['markets'][0];
 if(isset($data['events'][0]['products']))
 $products[$key][] = $data['events'][0]['products'];

 // $products[$key][] = $data['events'][0]['products'][0];

}

如果您在单个对象中有多个事件，请像这样使用

 foreach($yourdata as $key => $data){

          if(isset($data['events']))
         foreach($data['events'] as $event){
          if(isset($data['markets']))
          $markets[$key][] = $event['markets'];
          if(isset($data['products']))
          $products[$key][] = $event['products'];
         }

        }

        dd($markets,$products);

【讨论】：

cant' read $data['events'] 据说是未定义的索引：事件
输入dd($data)insight foreach 并检查您是否获得events 密钥并输入isset() 检查我的答案
每次打印都在里面添加，但我会在里面访问事件
你从哪里得到这些数据的？什么是格式？如果数据格式是 json ？然后转换为数组json_decode($jsondata) 然后执行 foreach 因为我使用了你的数据它工作正常
第二个例子没有错误，但是当我 dd 市场数组为空时
