PHP uses Curl to clone IP and refer steps

This time for everyone to bring PHP using Curl imitation IP and refer steps in detail, PHP use Curl imitation IP and refer of the note, the following is the actual case, together to see.

PHP Curl spoofed source IP and route Refer instance code 1:

Random ipfunction rand_ip () {$ip 2id= round (rand (600000, 2550000)/10000);//First method, direct generation $IP 3id= round (rand (600000, 2550000) /10000); $ip 4id= Round (rand (600000, 2550000)/10000); Here is the second method, randomly extracting $arr _1 = Array ("218", "218", "66", "66", "218", "218", "60", "60", "202", "204", "66", "66", "66", "59" in the following data, "61", "60", "222", "221", "66", "59", "60", "60", "66", "218", "218", "62", "63", "64", "66", "66", "122", "211"); $randarr = Mt_rand (0,count ($arr _1)-1); $ip 1id = $arr _1[$randarr]; return $ip 1id. ".". $ip 2id. ".". $ip 3id. ".". $ip 4id;}  Crawl page content function Curl ($url) {$ch 2 = Curl_init (); $user _agent = "mozilla/5.0 (Windows NT 6.1; WOW64) applewebkit/537.36 (khtml, like Gecko) chrome/29.0.1547.66 safari/537.36 ";//Impersonate Windows user normal access curl_setopt ($ch 2,  Curlopt_url, $url);  curl_setopt ($ch 2, Curlopt_timeout, 10); curl_setopt ($ch 2, Curlopt_httpheader, Array (' X-forwarded-for: '). Rand_ip (), ' Client-ip: '.   RAND_IP ()));//Tracing Returns 302 status code, continuing to crawl curl_setopt ($ch 2, Curlopt_header, true);   curl_setopt ($ch 2, Curlopt_returntransfer, true); curl_setopt ($ch 2, Curlopt_followlocation, true);  curl_setopt ($ch 2, Curlopt_nobody, false); curl_setopt ($ch 2, Curlopt_referer, ' http://www.baidu.com/');//Analog antecedents curl_setopt ($ch 2, curlopt_useragent, $user _agent  );  $temp = Curl_exec ($ch 2);  Curl_close ($ch 2); return $temp;}

PHP Curl spoofed source IP and route Refer instance Code 2:

<?php$postdata = Array ("User" = "root", "pwd" = "123456"), $headerIp = Array (' client-ip:88.88.88.88 ', ' X-forwa rded-for:88.88.88.88 ',); $refer = ' http://www.baidu.com '; $ch = Curl_init (); curl_setopt ($ch, Curlopt_url, ' http:// Localhost/phpdemo/test.php ');//Forged Source refercurl_setopt ($ch, Curlopt_referer, $refer);//Forged Source ipcurl_setopt ($ch, Curlopt_httpheader, $headerIp);//Submit post curl_setopt ($ch, Curlopt_postfields, $postData);//... Various curl attribute parameter settings $out_put = curl_exec ($ch); Curl_close ($ch); Var_dump ($out _put);
