Decode gzipped web page retrieved via cURL in PHP
提问by Ian
I'm retrieving a gzipped web page via curl, but when I output the retrieved content to the browser I just get the raw gzipped data. How can I decode the data in PHP?
我正在通过 curl 检索 gzipped 网页，但是当我将检索到的内容输出到浏览器时，我只获得原始 gzipped 数据。如何在 PHP 中解码数据？
One method I found was to write the content to a tmp file and then ...
我发现的一种方法是将内容写入 tmp 文件，然后...
$f = gzopen($filename,"r");
$content = gzread($filename,250000);
gzclose($f);
.... but man, there's got to be a better way.
....但是伙计，必须有更好的方法。
Edit: This isn't a file, but a gzipped html page returned by a web server.
编辑：这不是一个文件，而是一个由 web 服务器返回的 gzipped html 页面。

Versatile GUNZIP function:
多功能 GUNZIP 功能：
function gunzip($zipped) {
$offset = 0;
if (substr($zipped,0,2) == "\x1f\x8b")
$offset = 2;
if (substr($zipped,$offset,1) == "\x08") {
# file_put_contents("tmp.gz", substr($zipped, $offset - 2));
return gzinflate(substr($zipped, $offset + 8));
}
return "Unknown Format";
}
Example of integrating function with CURL:
将函数与 CURL 集成的示例：
$headers_enabled = 1;
curl_setopt($c, CURLOPT_HEADER, $headers_enabled)
$ret = curl_exec($c);
if ($headers_enabled) {
# file_put_contents("preungzip.html", $ret);
$sections = explode("\x0d\x0a\x0d\x0a", $ret, 2);
while (!strncmp($sections[1], 'HTTP/', 5)) {
$sections = explode("\x0d\x0a\x0d\x0a", $sections[1], 2);
}
$headers = $sections[0];
$data = $sections[1];
if (preg_match('/^Content-Encoding: gzip/mi', $headers)) {
printf("gzip header found\n");
return gunzip($data);
}
}
return $ret;
