不间断读取并解压gzip数据流

[wildlily980]

现在有一个数据流，它是active的，永远不关闭的那种，所以我要不停地读取它，这个已经实现了，
现在麻烦是，对方要求输出gzip的。这边要解压，各位大大，可有什么建议？php连gzdecode都还没有实现
对方说可以用 curl --compress url这种方式方便的访问，可是输出都跑屏幕上了，我要是能把它截到php里也好啊。
另外哪们有时间愿意做些小任务赚点小钱的，可以联系我。

那只是你偷懒没有去找

function gzdecode($data) {

做小任务赚钱的，论坛里很多.前两天发个帖子很多人表示有此意向。哈哈哈...

[wildlily980]

两位老大，真是好人啊，休息日也在。
谢谢唠叨，连代码都贴出来了，真是活雷锋啊。
其实google了两小时了，你贴的那个我也有印象，不过网上的内容太多，试了好多都不行，就来问问

[wildlily980]

哦，我想来了，唠 叨的那个我试过，是php手册上的，貌似不行，我再试试。

// Currently the only supported compression method:
$data = gzinflate($body);
这一行报 buffer error，
Warning: gzinflate() [function.gzinflate]: buffer error in
