title: Php echo json array with children
body: <p>I'm trying to echo the [steamid] from a json array. I keep getting an error message: "Notice: Undefined index: friends". I tried to create a loop and echo only the steamid's but I think i'm failing to target the [steamid] child element.</p>
  
  <pre><code>&lt;?php
  
  $jsondata = file_get_contents('http://api.steampowered.com/ISteamUser/GetFriendList/v0001/?key=&lt;api key&gt;&amp;steamid=&lt;steamid&gt;&amp;relationship=friend');
  
  $data = json_decode($jsondata, true);
  
  foreach ($data['friendslist'] AS $d){
  echo $d['friends'];
  }
  
  ?&gt;
  </code></pre>
  
  <p>This his how the json file looks:</p>
  
  <pre><code>    {
