技术贴：如何使用php+curl伪造IP进行url访问

本来作为技术贴，是不需要有背景说明的，之所以要做这个一个技术分享，主要是因为朋友注册了一个网站，需要进行分享传播，对于这种病毒式以及强制性要求传播的东西，我一直都是呲之以鼻，所以，想到了PHP内有个神器曰为：curl，于是乎，有了以下代码：

function task() {
        $url = "url";
        $headers = randIp();
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url); 
        curl_setopt($curl, CURLOPT_BINARYTRANSFER, true);  
        curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
        curl_setopt($curl, CURLOPT_USERAGENT,  "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0");      //模拟浏览器类型
        curl_setopt($curl, CURLOPT_TIMEOUT, 300);                               // 设置超时限制防止死循环    
        curl_setopt($curl, CURLOPT_HEADER, 0);                                  // 显示返回的Header区域内容    
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);                          // 获取的信息以文件流的形式返回
        $tmpInfo = curl_exec($curl);
        if (curl_errno($curl)) { 
            print "Error: " . curl_error($curl); 
        } else { 
            curl_close($curl); 
        } 
    }
//此函数提供了国内的IP地址
function randIP(){
       $ip_long = array(
           array('607649792', '608174079'), //36.56.0.0-36.63.255.255

       );
       $rand_key = mt_rand(0, 9);
       $ip= long2ip(mt_rand($ip_long[$rand_key][0], $ip_long[$rand_key][1]));
       $headers['CLIENT-IP'] = $ip; 
       $headers['X-FORWARDED-FOR'] = $ip; 

       $headerArr = array(); 
       foreach( $headers as $n => $v ) { 
           $headerArr[] = $n .':' . $v;  
       }
       return $headerArr;    
   }
