PHP CURL 代理发送数据

         $session = curl_init($request);
         curl_setopt ($session, CURLOPT_PROXY, $proxy);
         curl_setopt ($session, CURLOPT_POST, true);
         curl_setopt ($session, CURLOPT_POSTFIELDS, $postData);
         curl_setopt($session, CURLOPT_HEADER, false);
         curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
         $response = curl_exec($session);
         curl_close($session);

项目中遇到变态的东西，主机无法上网，但是机器又要向外部模拟POST提交信息。网上找了下，原来curl是支持proxy的。万幸！！！！
