Parsing JSON data using variables as keys

I am getting a JSON response which looks like this:

stdClass Object
(
    [location00] => Array
    (
        [0] => stdClass Object
        (
            [id_0] => Array
            (
                [0] => stdClass Object
                (
                    [id] => 1
                    [name] => Wanted by Aryurumoka
                    [gold_reward] => 58900
                    [event] => 0
                    [description] => Not provided.
                )
            )
        )
    )
)

For example, i am able to get [name] by $quests->location00[0]->id_0[0]->name.

Lets say i create a new variable $location = 'location00'. Now if i try $quests->$location[0]->id_0[0]->name', i am getting Undefined property: stdClass::$l error. I tried $location = 'location00[0]' as well however i have completly no idea why this happenes. How can i assign location00 to variable to use it while parsing JSON?

You can use associative array or $obj->{$var} :

<?php
$quests = json_decode($json, true);
$location = 'location00';
$name = $quests[$location][0]['id_0'][0]['name'];

I'd try to get new JSON, but you can interpolate object property retrieval with braces:

$quests->{$location}[0]
