How to convert object into array in php

The operating environment of this tutorial: windows10 system, PHP8.1 version, DELL G3 computer

Instructions

During the development process, we will encounter situations where we need to convert instantiated objects into arrays
For example, I want to export the processed data to excel, but the excel export only
supports the array format type

Example

For example, in the following code, I need to return the value data as an array type.
Although it is serialized into an array, it returns an object array at this time

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

Return 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 convert the object array into a string using json_encode and then convert it into an array. You can

 $data=json_decode(json_encode($data),true);

return as follows

array:8 [
  0 => array:4 [
    "statistical_date" => "2021-09-10"
    "order_num" => 1
    "play_type_count" => 1
    "invalid_order_count" => 1
  ]
  1 => array:4 [
    "statistical_date" => "2021-09-09"
    "order_num" => 6
    "play_type_count" => 6
    "invalid_order_count" => 3
  ]
]
