如何利用php做不同虚拟（模拟）ip访问网站

因为ip被限制，无法正常的访问网站，那么如何利用php做不同虚拟ip访问网站呢？下面编程教程网小编带大家了解一下！

实现代码如下：

<?php
function doCurl($url, $data=array(), $header=array(), $referer='', $timeout=30){
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
  curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);

  // 模拟来源
  curl_setopt($ch, CURLOPT_REFERER, $referer);
  
  $response = curl_exec($ch);

  if($error=curl_error($ch)){
    die($error);
  }
  
  curl_close($ch);

  return $response;
}

// 调用
$url = 'http://www.example.com/server.php';
$data = array();
  
// 设置IP
$header = array(
  'CLIENT-IP: 192.168.1.100',
  'X-FORWARDED-FOR: 192.168.1.100'
);
  
// 设置来源
$referer = '设置访问网站域名';
  
$response = doCurl($url, $data, $header, $referer, 5);
  
echo $response;
?>
