下面是我的代码,我网上找的高匿代理ip做实验,抓取http://www.ip138.com/ 但是上面显示的还是我真实ip说明代理ip没有起作用,有谁能分析下到底为什么。 function get_html($url,$data=array(),$html_char='UTF-8',$is_ssh='http'){    $ch = curl_init();    
   curl_setopt($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'];
