File_get_contents cannot do this.

function curl_get($durl) {
  $t = parse_url($durl);
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL,$durl);
  curl_setopt($ch, CURLOPT_TIMEOUT,5);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
  curl_setopt($ch, CURLOPT_REFERER, "http://$t[host]/");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
  $r = curl_exec($ch);
  curl_close($ch);
  return $r;
}

echo curl_get( 'http://www.mouser.cn/Search/Refine.aspx?Keyword=39000038');
