PHP实现代理IP

PHP程序在服务器上运行，不在浏览者的机器上运行，只是把运行生成的HTML结果发送给浏览者的浏览器程序，不可能修改浏览者的代理设置。

PHP可以修改服务器机器的代理设置，方法是修改注册表。

<?php

//授权 IP

$ips = ['119.29.29.29', '8.8.8.8']

//代理IP直接退出 

empty($_SERVER['HTTP_VIA']) or exit('Access Denied')

//防止快速刷新 

session_start()

$seconds = '3' //时间段[秒] 

$refresh = '5' //刷新次数 

//设置监控变量 

$cur_time = time()

if (isset($_SESSION['last_time'])) {

   $_SESSION['refresh_times'] += 1

} else {

   $_SESSION['refresh_times'] = 1

   $_SESSION['last_time']     = $cur_time

}

//处理监控结果 

if ($cur_time - $_SESSION['last_time'] < $seconds) {

   if ($_SESSION['refresh_times'] >= $refresh && ! in_array($getIP, $ips)) {

       //跳转至攻击者服务器地址 

       header(sprintf('Location:%s', '

))

       exit('Access Denied')

   }

} else {

   $_SESSION['refresh_times'] = 0

   $_SESSION['last_time']     = $cur_time

}

function getIP() {

   if (getenv('HTTP_CLIENT_IP')) {

       $ip = getenv('HTTP_CLIENT_IP')

   } elseif (getenv('HTTP_X_FORWARDED_FOR')) {

       $ip = getenv('HTTP_X_FORWARDED_FOR')

   } elseif (getenv('HTTP_X_FORWARDED')) {

       $ip = getenv('HTTP_X_FORWARDED')

   } elseif (getenv('HTTP_FORWARDED_FOR')) {

       $ip = getenv('HTTP_FORWARDED_FOR')

   } elseif (getenv('HTTP_FORWARDED')) {

       $ip = getenv('HTTP_FORWARDED')

   } else {

       $ip = $_SERVER['REMOTE_ADDR']

   }

   return $ip

}

function curl_string ($url,$timeout = 3,$proxy=1){

$ua = array('Mozilla','Opera','Microsoft Internet Explorer','ia_archiver')

$op = array('Windows','Windows XP','Linux','Windows NT','Windows 2000','OSX')

$agent = $ua[rand(0,3)].'/'.rand(1,8).'.'.rand(0,9).' ('.$op[rand(0,5)].' '.rand(1,7).'.'.rand(0,9).'en-US)'

Tor 地址与端口

$tor = 'http://www.aimilife.com' //这里是你的代理服务器

连接超时设置

$timeout = 3

$ack = curl_init()

if($proxy)

{

curl_setopt($ack, CURLOPT_PROXY, $tor)

}

curl_setopt($ack, CURLOPT_URL, $url)

curl_setopt($ack, CURLOPT_HEADER, 0)

curl_setopt($ack, CURLOPT_USERAGENT, $agent)

curl_setopt($ack, CURLOPT_RETURNTRANSFER, 1)

curl_setopt($ack, CURLOPT_FOLLOWLOCATION, 1)

curl_setopt($ack, CURLOPT_TIMEOUT, $timeout)

$result = curl_exec($ack)

curl_close($ack)

return $result

}
