这个网页怎么curl不了啊

Question

之前可以的<?php
function n_r($url) {
$ch = curl_init(); 
$timeout = 10; 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_REFERER, 'http://www.hahasport.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
@ $c = curl_exec($ch);
curl_close($ch);
$c = mb_convert_encoding($c, 'GBK', 'UTF-8');
return $c; 
}
$a = 'http://www.hahasport.com/vt-0/10/42/vt-104227.html'; 
$str = n_r($a);
echo $str;
?>
