title: file_get_contents returns 403 forbidden
body: <p>I am trying to make a sitescraper. I made it on my local machine and it works very fine there. When I execute the same on my server, it shows a 403 forbidden error.
  I am using the <a href="http://simplehtmldom.sourceforge.net/manual.htm">PHP Simple HTML DOM Parser</a>. The error I get on the server is this:</p>
  
  <blockquote>
    <p>Warning:
    file_get_contents(http://example.com/viewProperty.html?id=7715888)
    [function.file-get-contents]: failed
    to open stream: HTTP request failed!
    HTTP/1.1 403 Forbidden in
    /home/scraping/simple_html_dom.php on
    line 40</p>
  </blockquote>
  
  <p>The line of code triggering it is:</p>
  
  <pre><code>$url="http://www.example.com/viewProperty.html?id=".$id;
  
  $html=file_get_html($url);
  </code></pre>
  
  <p>I have checked the php.ini on the server and allow_url_fopen is On. Possible solution can be using curl, but I need to know where I am going wrong.</p>
