Curl grab get to http/1.1 403 Forbidden

To a friend to do a crawl number of small programs, I use the following code to get no data, the header is set to 1, the following results
http/1.1 403 Forbidden accept-ranges:bytes Date:sat, Nov 03:11:05 GMT age:0 connection:close X-cache:miss

Here is the code, how can i solve it? Thank you.
$url = "http://www.btspread.com/search/abp108";
$ch =curl_init ();
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, curlopt_header,1);
curl_setopt ($ch, curlopt_returntransfer,1);
curl_setopt ($ch, curlopt_post,1);
echo $xml =curl_exec ($ch);
Curl_close ($ch);
?>
