Does anyone know how to uncompress the contents of a gzip file that i got with curl?

for example: http://torcache.com/torrent/63ABC1435AA5CD48DCD866C6F7D5E80766034391.torrent

responded 

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 09 Jun 2010 01:11:26 GMT
Content-Type: application/x-bittorrent
Content-Length: 52712
Last-Modified: Tue, 08 Jun 2010 15:09:58 GMT
Connection: keep-alive
Expires: Fri, 09 Jul 2010 01:11:26 GMT
Cache-Control: max-age=2592000
Content-Encoding: gzip
Accept-Ranges: bytes

then the compressed gzip,

i tried gzdecode but doesn't work , gzeflate as well doesn't they simply don't get any response, and the contents of the files are no more than 2k

php curl gzip gunzip

Use gzdecode:

<?php
    $c = file_get_contents("http://torcache.com/" .
        "torrent/63ABC1435AA5CD48DCD866C6F7D5E80766034391.torrent");
    echo gzdecode($c);

gives

Have you tried gzuncompress or gzinflate?

gzdeflate compresses, the opposite of what you want. To be honest, I can't figure out how gzdecode differs from normal uncompressing.

There's also the cURL option CURLOPT_ENCODING:

The contents of the "Accept-Encoding: " header. This enables decoding of the response. Supported encodings are "identity", "deflate", and "gzip". If an empty string, "", is set, a header containing all supported encoding types is sent.

It seems to mean it'll automatically decompress the response, but I haven't tested that.
