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。


------解决方案--------------------
别的不说,我就是来拿分的.楼主记得给全分



$curl=curl_init('http://www.163.com');
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl,CURLOPT_USERAGENT,'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322)');
$html=curl_exec($curl);
var_dump($html);


$curl=curl_init('http://www.sohu.com');
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
curl_setopt($curl,CURLOPT_USERAGENT,'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322)');
$html=curl_exec($curl);
//$html=strstr($html,'<');
$html=gzdecode($html);
var_dump($html);


function gzdecode($data) {
$len = strlen($data);
if ($len < 18
------解决方案--------------------
strcmp(substr($data,0,2),"\x1f\x8b")) {
return null; // Not GZIP format (See RFC 1952)
}
$method = ord(substr($data,2,1)); // Compression method
$flags = ord(substr($data,3,1)); // Flags
if ($flags & 31 != $flags) {
// Reserved bits are set -- NOT ALLOWED by RFC 1952
return null;
}
// NOTE: $mtime may be negative (PHP integer limitations)
$mtime = unpack("V", substr($data,4,4));
$mtime = $mtime[1];
$xfl = substr($data,8,1);
$os = substr($data,8,1);
$headerlen = 10;
$extralen = 0;
$extra = "";
if ($flags & 4) {
// 2-byte length prefixed EXTRA data in header
if ($len - $headerlen - 2 < 8) {
return false; // Invalid format
}
$extralen = unpack("v",substr($data,8,2));
$extralen = $extralen[1];
