title: Extract value from an array in php
body: <p>In my code, $return returns an array of data. I am trying to extract the [2] value in that array. For some reason it just returns the whole array instead of the value I am trying to extract. I feel like this is really simple and I am just overlooking something.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>$url = 'https://sandbox.familysearch.org/platform/tree/persons/KWWM-5R1/portrait?access_token=' . $_SESSION['fs-session'];
  
  $return = print_r(get_headers($url));
  
  echo $return[2];
  </code></pre>
  
  <p>And here is a snip from the array that was printed:</p>
  
  <pre><code>Array ( [0] =&gt; HTTP/1.1 307 Temporary Redirect [1] =&gt; Server: Apache-Coyote/1.1 [2] =&gt; Location: https://integration.familysearch.org/sandbox/v2/TH-501-48051-27-34/thumb200.jpg?ctx=ArtCtxPublic )
  </code></pre>
  
  <p>How can I get the [2] value?</p>
