title: Facebook page feed doesn't work with php file_get_contents()
body: <p>When I go to this url in by browser, it shows me the json feed i expect:</p>
  
  <p><a href="https://www.facebook.com/feeds/page.php?format=json&amp;id=237173582992285" rel="noreferrer">https://www.facebook.com/feeds/page.php?format=json&amp;id=237173582992285</a></p>
  
  <p>When in PHP I do a </p>
  
  <pre><code>&lt;?php
  print_r(file_get_contents('https://www.facebook.com/feeds/page.php?format=json&amp;id=237173582992285'));
  ?&gt;
  </code></pre>
  
  <p>I get an html page saying my browser is not supported by facebook and that I should upgrade.   How do I make the file_get_contents return the json feed I'm expecting?</p>
  
  <p><strong>Additional Notes</strong>  I also tried from bash <code>wget https://www.facebook.com/feeds/page.php?format=json&amp;id=237173582992285</code> and the file I downloaded also has html content saying browser not supported. </p>
