title: PHP cURL custom headers
body: <p>I'm wondering if/how you can add custom headers to a cURL HTTP request in PHP. I'm trying to emulate how iTunes grabs artwork and it uses these non-standard headers:</p>
  
  <pre><code>X-Apple-Tz: 0
  X-Apple-Store-Front: 143444,12
  </code></pre>
  
  <p>How could I add these headers to a request?</p>
