curl抓取得到HTTP/1.1 403 Forbidden

给朋友做一个抓取番号的小程序,我使用下面这段代码得不到任何数据,将header设为1,得到如下结果
HTTP/1.1 403 Forbidden Accept-Ranges: bytes Date: Sat, 15 Nov 2014 03:11:05 GMT Age: 0 Connection: close X-Cache: MISS

以下为代码,请问该如何解决呢?谢谢了
$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);
?>

                $headers['User-Agent'] = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:33.0) Gecko/20100101 Firefox/33.0';		$url="http://www.btspread.com/search/%E9%A2%A8%E9%96%93";		$headerArr = array(); 		foreach( $headers as $n => $v ) { 		    $headerArr[] = $n .':' . $v;  		}		$ch=curl_init();		curl_setopt($ch,CURLOPT_URL,$url);		curl_setopt($ch,CURLOPT_HEADER,1);		curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);		curl_setopt ($ch, CURLOPT_HTTPHEADER , $headerArr );		echo $xml=curl_exec($ch);		curl_close($ch);
