Curl 采集乱码与采集不到 PHP
PHP程序是用gbk2312编码的：
$url = "http://www.sina.com.cn";//gbk2312编码
//$url = "http://www.163.com";//gbk2312编码
//$url = "http://www.sohu.com";//gbk2312编码
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER , true);//返回获取的输出的文本流
$ret = curl_exec($ch);
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
curl_close($ch);
echo $ret;
?>
在采集sina.com.cn时，是正常的，但是采集163.com时是为空的，采集sohu.com时是丢码的.
这是怎么回事呢？如何解决？有哪位怎么呀？先谢谢了！！！没多少分了，不好意思。
