title: PHP ini file_get_contents external url
body: <p>I use following PHP function:</p>
  
  <p><code>file_get_contents('http://example.com');</code></p>
  
  <p>Whenever I do this on a certain server, the result is empty. When I do it anywhere else, the result is whatever the page's content may be. When I however, on the server where the result is empty, use the function locally - without accessing an external URL (<code>file_get_contents('../simple/internal/path.html');</code>), it <em>does</em> work.</p>
  
  <p>Now, I am pretty sure it has something to do with a certain php.ini configuration. What I am however not sure about is, <em>which</em> one. Please help.</p>
