How do I target nested JSON objects in php, and echo them?

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...

Thank you very much. You are much too kind. A little bit new to this, even the easiest of tutorials (the duplicate mark, for instance) are too confusing.

Of course, but can't do it instantly, waiting for a timer!

@JohnSmith Mark this as the answer. Don't hold him hostage while you ask completely irrelevant, random questions in the comments section.

<?php

//This is your json string
$string = {"57690":{"success":true,"data":{"type":"game","name":"Tropico 4: Steam Special Edition"...

//Turn JSON string into object
$data = json_decode($string);

//Turn your object into an array (easier to work with in this case)
$data = (Array)$data;

//Get name of item with "57690" key
$name = $data["57690"]->data->name;

//Echo the name
echo($name);

//You can also echo out all names of all items like this:
foreach($data as $key => $item)
{
    echo($item->data->name);
}

Thank you, I think I get the concept now! While I'm typing I might aswell ask, how do I structure this API so it's readable? It's just one long series of text looking in the browser..

depending on your editor, you may have built-in features or plugins available to auto-format JSON. I use Notepad++ and there is a plugin called "JSON Viewer" that auto-formats for me.

Perfect, just what I'm looking for. This community is too scrub-friendly. Thanks.
