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 ] ]
