referer是php用來判斷頁面上級來源頁面的一個超級變局變量了,咱們能夠使用referer來判斷是從那個頁面進入到此頁面了,這樣咱們能夠進行更好的跟蹤了,下面我就來給各位朋友整理了幾種僞造頁面referer來源例子,但願例子能給各位朋友.

file_get_contents方法,代碼以下:

$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就僞造來源的重要參數了,這個什麼好說的很是的簡單.

CURL方式,代碼以下:

$ch = curl_init();
curl_setopt ($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僞造來源頁面很是的簡單這是它的優勢了,因此咱們只要在頁面加上curl_setopt ($ch,CURLOPT_REFERER,"http://www.phpfensi.com/");就能夠了.

SOCKET方式,代碼以下:

$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:三種性能比對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)\r\nAccept:*/*\r\nReferer:」 . $referer . 「\r\nCookie:」 . $cookie));
$file = file_get_contents($url, false , stream_context_create($option));

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