phpcurl

我在 http://ip.qiaodm.com/上面找的高匿代理
这是我的代码我curl用了代理ip做抓取，按理说应该显示的是我代理的ip但是还是显示的我的本机IP。 有谁知道为什么

function get_html($url,$data=array(),$html_char='UTF-8',$is_ssh='http'){

<code>           $ch = curl_init();               curl_setopt($ch, CURLOPT_URL, $url);             curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);            curl_setopt($ch, CURLOPT_PROXY,'111.12.117.67');            curl_setopt($ch, CURLOPT_PROXYPORT,'83');            curl_setopt ($ch, CURLOPT_HTTPHEADER, array('CLIENT-IP:113.207.63.26', 'X-FORWARDED-FOR:113.207.63.26'));           curl_setopt ($ch, CURLOPT_TIMEOUT, 6000);               curl_setopt ($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9) Gecko/2008052906 Firefox/3.0');           if($is_ssh=='SSL'){           curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);            }           curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);             if(!empty($data)){                       curl_setopt($ch, CURLOPT_POST, true);                           curl_setopt($ch, CURLOPT_POSTFIELDS, $data);                         }           $output = curl_exec($ch);            if($html_char!='UTF-8'){                $output=mb_convert_encoding($output, "UTF-8", $html_char);             }                          $info = curl_getinfo($ch);           curl_close($ch);        $returntemp = array('output'=>$output,'info'=>$info);        return $returntemp['output'];       }</code>
