如何在php中解析使用GZip压缩的响应？

我正在请求一个带有链接的api

如您所见，响应是可下载的.gz格式文件。实际上，它是xml格式文件。 我的问题是如何在php脚本和echo xml格式中解析使用GZip压缩的响应？ 谢谢大家!

header('content-type:text/html;charset=utf-8');
if (substr_count($_SERVER["HTTP_ACCEPT_ENCODING"], "gzip")) ob_start("ob_gzhandler"); else ob_start();
$appkey ='kwaninmacau';
$url ='http://services.eoddsmaker.net/demo/feeds/V1.0/markets.ashx';
$params ='l=1&bid=43&sid=50&cid=58&lid=10&u='.$appkey.'&p='.$appkey;
echo datafeedurl($url,$params,0);
function datafeedurl($url,$params=false,$ispost=0){
..
curl_setopt( $ch, CURLOPT_ENCODING , "gzip");
}

您可以为Gzip使用以下代码

curl_setopt($ch,CURLOPT_ENCODING , "gzip");

---

正如您所看到的，响应是.gz格式的，不，不是。服务器显示内容类型：application/x-gzip，但这是错误的！它是一个XML文件，名称为markets_20151127T065210.gz

用户curl并检查此链接无响应。我已添加到curl函数选项。警告，此API已损坏。表示内容类型：application/x-gzip；charset=UTF-8，但实际上，它提供了一个XML文件，文件名为markets_20151127T065210.gz是的，您是对的。实际上，它是.xml文件，其后缀被修改为.gz。这是一个重要的关键问题。如何处理？没有响应。我已经添加了curl函数选项。@JackyKwan您是否检查了服务器设置ob_startob_gzhandler或php_ini？@JackyKwan您是否可以将Gzip代码放入.htaccess文件？php.ini应该没有问题。你这是什么意思？这是我的测试url@JackyKwan，我们可以将这种类型的.htaccess代码用于Gzip。当您发布脚本时，响应是。xml是错误代码？？？事实上，如果您下载xxx.gz文件，然后将其后缀名修改为.xml，您将获得完整的xml内容。那没问题@JackyKwan成功了！您的xml文件显示。。。。。。。我不知道这是不是你想要的，或者这是个错误。。无论如何，用echo$xml替换var_转储；您将得到您的xml:pHi cool man，我相信您得到了正确的结果。然而，为什么我得到了这一页空白？实际上，我在第123行的/home/andy1573166/public\u html/new2.php中回显$xmlWarning:curl_setopt:supplied参数不是有效的文件句柄资源
