chunked编码问题
php采集到的数据是chunked传输编码，gzip压缩格式的
chunk编码的思路貌似是：将数据分块传输，每一块分为头部和主体字段，头部包含主体信息的长度且以16进制表示，头部和主体以回车换行符分隔，最后一块以单行的0表示分块结束。。
响应头信息：
array
(
[0] => http/1.1 200 ok
[1] => server: dict/34002
[2] => date: wed, 17 dec 2014 06:49:22 gmt
[3] => content-type: text/html; charset=utf-8
[4] => transfer-encoding: chunked
[5] => connection: keep-alive
[6] => keep-alive: timeout=60
[7] => cache-control: private
[8] => last-modified: wed, 17 dec 2014 04:57:49 gmt
[9] => expires: wed, 17 dec 2014 06:49:22 gmt
[10] => set-cookie: uvid=vjencotsvyjc; expires=thu, 31-dec-37 23:55:55 gmt; domain=.dict.cn; path=/
[11] => content-encoding: gzip
)

if($this->response_num==200)
{
if($this->is_chunked)
{
//读取chunk头部信息，获取chunk主体信息的长度
$chunk_size = (int)hexdec(fgets($this->conn));
//
while(!feof($this->conn) && $chunk_size > 0)
{
//读取chunk头部指定长度的信息
$this->response_body .= fread( $this->conn, $chunk_size );
fseek($this->conn, 2, seek_cur);
$chunk_size = (int)hexdec(fgets( $this->conn,4096));
}
}
else
{
$len=0;
//读取请求返回的主体信息
while($items = fread($this->conn, $this->response_body_length))
{
$len = $len+strlen($items);
$this->response_body = $items;
//当读取完请求的主体信息后跳出循环，不这样做，貌似会被阻塞！！！
if($len >= $this->response_body_length)
{
break;
}
}
}
if($this->is_gzip)
{
$this->response_body = gzinflate(substr($this->response_body,10));
}
$this->gettrans($this->response_body);
}

基本上每次都会出现这个提示：
warning: gzinflate(): data error in e:\codeedit\php\http\dict.php on line 384
偶尔能正常解析，应该是chunked解码有问题，查看过一些资料，也变换过集中解码方式，但还是功亏一篑
------解决思路----------------------
你可用 gzdecode 解码
