  <p>Here's my php code so far. I've tried quite a few different things. I normally use xml feeds which seem to be easy for me to setup for what I need. I'm not sure what I'm missing here.</p>
  
  <pre class="lang-php prettyprint-override"><code>$url = 'https://whatever.com/api/external/v4/widget?userId=whatever&amp;tag=featured'; // path to your JSON file
  $data = file_get_contents($url); // put the contents of the file into a variable
  $performers = json_decode($data, true); // decode the JSON feed
  
  foreach ($performers as $performer) {
    $info = $performer[0]["username"];
    echo $info;
  }
  </code></pre>
  
  <p>I'm only getting the first username and then error messages.</p>
  
  <p>Warning: Illegal string offset 'username' in /whatever</p>
  
  <p>Can anyone help with this?</p>
