Instructions

During the development process, we will encounter the need to convert instantiated objects into arrays Situation

For example, I want to export the processed data to excel, but the excel export only

supports array format type

Example

For example, the following code I need the return value data to be an array type.

Although it is serialized into an array, an object array is returned at this time.

 $data=$orderList->getCollection()->map(function ($order){
            return new OrderResponse($order);
        });
    dd($data->toArray());

The return value is as follows

^ array:8 [
  0 => app\admin\Responses\OrderResponse {#122
    +"statistical_date": "2021-09-10"
    +"order_num": 1
    +"play_type_count": 1
    +"invalid_order_count": 1
  }
  1 => app\admin\Responses\OrderResponse {#119
    +"statistical_date": "2021-09-09"
    +"order_num": 6
    +"play_type_count": 6
    +"invalid_order_count": 3
  }
]

Processing method

Use json_decode() to convert the string into an array

First use json_encode to convert the object array into a string and then convert it into an array

$data=json_decode(json_encode($data),true);
返回如下

array:8 [
  0 => array:4 [
    "statistical_date" => "2021-09-10"
    "order_num" => 1
    "play_type_count" => 1
    "invalid_order_count" => 1
  ]

    "order_num" => 6
