title: JSON URL Requests Returns Null Even Though json_last_error returns 0
body: <p>So, I'm using file_get_contents(url) to return some JSON data.
  When I use <code>var_dump(json_decode($result, true));</code> it always returns <code>NULL</code></p>
  
  <p>I used <code>echo json_last_error();</code> and that returns 0, indicating no error.</p>
  
  <p>I've spent ages trying to find a solution to my problem.
  (Also this is the first time I've ever used JSON)</p>
  
  <p>What could possibly be wrong here?</p>
  
  <p>Here is the value of result when I just request 1 item (It's long, so I'm just gonna show 1)</p>
