Getting all from json api array using php

I wanna improve on how to fetch data from an API. In this case I want to fetch every app-id from the Steam API, and list them one per line in a .txt file. Do I need an infinite (or a very high-number) loop (with ++ after every iteration) to fetch everyone? I mean, counting up from id 0 with for example a foreach-loop? I'm thinking it will take ages and sounds very much like bad practice.

How do I get every appid {"appid:" n} from the response of http://api.steampowered.com/ISteamApps/GetAppList/v0001? 

<?php
    //API-URL
    $url = "http://api.steampowered.com/ISteamApps/GetAppList/v0001";
    //Fetch content and decode
    $game_json = json_decode(curl_get_contents($url), true);

    //Define file
    $file = 'steam.txt';
    //This is where I'm lost. One massive array {"app": []} with lots of {"appid": n}. 
    //I know how to get one specific targeted line, but how do I get them all?
    $line = $game_json['applist']['apps']['app']['appid'][every single line, one at a time]
    //Write to file, one id per line.
    //Like:
    //5
    //7
    //8
    //and so on
    file_put_contents($file, $line, FILE_APPEND);
?>

Any pointing just in the right direction will be MUCH appreciated. Thanks!

You don't need to worry about counters with foreach loops, they are designed to go through and work with each item in the object.

$file      = "steam.txt";
$game_list = "";
$url       = "http://api.steampowered.com/ISteamApps/GetAppList/v0001";
$game_json = file_get_contents($url);
$games     = json_decode($game_json);

foreach($games->applist->apps->app as $game) {
    // now $game is a single entry, e.g. {"appid":5,"name":"Dedicated server"}
    $game_list .= "$game->appid\n";
}

file_put_contents($file, $game_list);

Now you have a text file with 28000 numbers in it. Congratulations?
