referer是php用来判断页面上级来源页面的一个超级变局变量了,我们可以使用referer来判断是从那个页面进入到此页面了,这样我们可以进行更好的跟踪了,下面我就来给各位朋友整理了几种伪造页面referer来源例子,希望例子能给各位朋友.

file_get_contents方法,代码如下:

$opt=array('http'=>array('header'=>"Referer: $refer")); 

$context=stream_context_create($opt); 

$file_contents = file_get_contents($url,false, $context);

分析:file_get_contents中stream_context_create就伪造来源的重要参数了,这个什么好说的非常的简单.

CURL方式,代码如下:

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, "http://www.phpfensi.com");
curl_setopt ($ch, CURLOPT_REFERER, "http://www.phpfensi.com/");
curl_exec ($ch);
curl_close ($ch);

分析:curl伪造来源页面非常的简单这是它的优点了,所以我们只要在页面加上curl_setopt ($ch,CURLOPT_REFERER,"http://www.phpfensi.com/");就可以了.

SOCKET方式,代码如下:

$server = 'www.phpfensi.com';
$host = 'www.phpfensi.com';
$target = 'index.php';
$referer = 'http://www.phpfensi.com/'; // Referer
$port = 80;
$fp = fsockopen($server, $port, $errno, $errstr, 30);
if (!$fp){
  echo "$errstr ($errno)＼n";
}else{
$out = "GET $target HTTP/1.1＼r＼n";
$out .= "Host: $host＼r＼n";
$out .= "Referer: $referer＼r＼n";
$out .= "Connection: Close＼r＼n＼r＼n";
fwrite($fp, $out);
while (!feof($fp)){
echo fgets($fp, 128);
}
fclose($fp);
}

友情提示:三种性能比对fsockopen是最好的,$optionget = array(‘http’ => array(‘method’ => “GET”, ‘header’ => “User-Agent:Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0) Accept:*/* Referer:” . $referer . “ Cookie:” . $cookie));
$file = file_get_contents($url, false , stream_context_create($option));

<?php
echo "<hr />";
echo $_SERVER["HTTP_REFERER"];
?>
