php curl获取代理

Question

I am using a PHP script in Windows to make a curl request to successfully make a SOAP request, and I'm trying to track down exactly how this successful request is made to replicate it in C#.NET.

How can I use PHP to detect which proxy server curl is going to use?

I was hoping there might be a curl_getopt in php curl, so I could do something like:

curl_getopt(CURLOPT_PROXY);

but alas it doesn't exist.

Is there any way for me to find out which proxy server php curl will be connecting through?

1. You tell curl what proxy to use, and not viaversa:

function wget($url)
{
    $options = array(
        CURLOPT_URL             => $url,
        CURLOPT_HEADER          => false,
        CURLOPT_FOLLOWLOCATION  => true,
        CURLOPT_RETURNTRANSFER  => true,
        CURLOPT_TIMEOUT         => 30,
        CURLOPT_PROXY           => '...proxy.ip...',
        CURLOPT_PROXYPORT       => '...proxy.port...',
        CURLOPT_USERAGENT       => 'Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.8.0.9) Gecko/20061206 Firefox/1.5.0.9',
    );
    $ch = curl_init();
    curl_setopt_array($ch, $options);
    $content = curl_exec($ch);
    $error = curl_error($ch);
    return (!$error && $content) ? $content : null;
}

3. Override curl_setopt() function

http://php.net/manual/en/function.override-function.php

p.s. you should probably need http://php.net/manual/en/function.rename-function.php

4. Use runkit to override functions
