由于JSON中的奇怪OBJECT名称，难以以PHP数组的形式获取JSON数据

Question

I am fetching data from JSON in the form of PHP array. But I am not able to fetch it due to strange OBJECT titles.

E.g. here is simply example

[car] => stdClass Object
    (
        [model] => stdClass Object
            (
                [year] => 2018
                [company] => Honda
                [condition] => Good
            )

    )

Now I can fetch "condition" like this $car->model->condition;

But in my case, the JSON is like this

[car] => stdClass Object
    (
        [field_set_key="profile",username="sammy"] => stdClass Object
            (
                [year] => 2018
                [company] => Honda
                [condition] => Good
            )

    )

I am not able to fetch "condition" value due to this strange object [field_set_key="profile",username="sammy"]

What should I do?

$car->[ ?????? ]->condition;

Answer 1

Using the {} syntax you can address that like this

echo $car->{'field_set_key="profile",username="sammy"'}->condition;

Its ugly and it would really be better if you got the people producing this data to fix their code.

Example

$car = new stdClass;
$b = new stdClass;

$b->year = 2018;
$b->company = 'Honda';
$b->condition =  'good';

$car->{'field_set_key="profile",username="sammy"'} = $b;

print_r($car) . PHP_EOL;

echo 'The condition of the '
        . $car->{'field_set_key="profile",username="sammy"'}->year . ' '
        . $car->{'field_set_key="profile",username="sammy"'}->company
        . ' is ' . $car->{'field_set_key="profile",username="sammy"'}->condition;

RESULTS

stdClass Object
(
    [field_set_key="profile",username="sammy"] => stdClass Object
        (
            [year] => 2018
            [company] => Honda
            [condition] => good
        )
)

The condition of the 2018 Honda is good
