How to get an option previously set with curl_setopt()?
提问by hakre
I'm just wondering as there is no curl_getopt() function, how it is possible to find out which value has been set for a specific option with curl_setopt()previously?
我只是想知道因为没有 curl_getopt() 函数，如何才能找出curl_setopt()以前为特定选项设置的值？

Question:Is there a way to get the current curl option settings? Like a curl_getopt() or curl_showopts()?
Answer:Yes and no. There is curl_getinfo()which will show you some info about the last connection, but I suspect it's not what you're looking for. It's a weakness in curl, IMHO.
问题：有没有办法获取当前的 curl 选项设置？像 curl_getopt() 或 curl_showopts()？
回答：是和否。有 curl_getinfo()会向您显示有关上次连接的一些信息，但我怀疑这不是您要查找的信息。恕我直言，这是卷曲的弱点。
My suggestion (and others) is to encapsulate cURL into a class where your $cURL->setOpt()function also stores the value for retrieval later.
我的建议（和其他建议）是将 cURL 封装到一个类中，您的$cURL->setOpt()函数还存储该值以供稍后检索。
The multirequestPHP library has this functionality (and then some!):
多请求PHP 库有这个功能（还有一些！）：
$request = new \MultiRequest\Request($url);
$request->setCurlOption(CURLOPT_PROXY, $proxy);
// ...
$curlOptions = $request->getCurlOptions();
list($proxyIp, $proxyPort) = explode(':', $curlOptions[CURLOPT_PROXY]);

Possibly curl_getinfo()may satisfy some of your needs.
If not, you can write a wrapper of curl_setopt()which saves all options to an array.
或许curl_getinfo()可以满足你的一些需求。如果没有，您可以编写一个包装器curl_setopt()，将所有选项保存到一个数组中。
