如何将数据正确格式化为JSON

Question

I am working on hotels API, which needs to send data in JSON form,

But my JSON form is wrong and the API is not working.

My code is:-

$json = json_encode([
    'RoomGuests' => [ json_encode(["NoOfAdults"=> 1,"NoOfChild"=> 0,"ChildAge"=> null])],
]);

And my output is :-

{
"RoomGuests": [
"{\"NoOfAdults\":1,\"NoOfChild\":0,\"ChildAge\":null}"
 ] }

And I want the result like this:-

{
"RoomGuests": [{
    "NoOfAdults": 1,
    "NoOfChild": 0,
    "ChildAge": null
}],  }

Please let me know how to solve this issue.

Answer 1

Use this

$json = json_encode([
    'RoomGuests' => [["NoOfAdults"=> 1,"NoOfChild"=> 0,"ChildAge"=> null]],
]);

echo $json;

This will results into

{
    "RoomGuests": [
        {
            "NoOfAdults": 1,
            "NoOfChild": 0,
            "ChildAge": null
        }
    ]
}
