如何在php中定位嵌套的JSON对象，并回显它们？

Question

Okay, so I think you get what I wanna do by just watching the code.

//Get JSON text file (Steam API)
$json = file_get_contents('http://store.steampowered.com/api/appdetails?appids=57690');

//Decode JSON
$game_json = json_decode($json, true);

//Target game name and echo it
echo $game_json['name'];

The JSON itself comes in this order (unstructured, very sorry):

{"57690":{"success":true,"data":{"type":"game","name":"Tropico 4: Steam Special Edition"

So my target is ""name":"Tropico 4: Steam Special Edition"", which is what I want to echo on my page. I'm not sure if it helps, but "name": appears once, is something like [0] needed in my code to target the first? Is the nesting what's stopping me here, or is the $game_json['name']; an incorrect way of targeting?

ANY tips and/or help will be much appreciated. Thanks.

In the future, use print_r($game_json) to check the array structure.

<?php
$json = file_get_contents('http://store.steampowered.com/api/appdetails?appids=57690');
$game_json = json_decode($json, true);
echo $game_json['57690']['data']['name'];
//Tropico 4: Steam Special Edition
echo $game_json['57690']['data']['required_age'];
//0
//etc...
