Use PHP to forge the referer address

Many times we use the referer address. By judging where the previous page came from, we can learn a lot of information, but now the referer is not that reliable data because we can forge the referer address. Here we introduce the implementation methods of CURL, SOCKET, and file_get_contents respectively. The detailed codes are as follows:

CURL method

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

SOCKET method

$server = ‘www.hujuntao.com’;
$host = ‘www.hujuntao.com’;
$target = ‘index.php’;
$referer = ‘http://www.hujuntao.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);
}

file_get_contents method

$opt=array(‘http’=>array(‘header’=>"Referer: $refer"));
$context=stream_context_create($opt);
$file_contents = file_get_contents($url,false, $context);

Through the above In the code, we disguise the referer address as http://www.hujuntao.com. You can write a piece of code:

$_SERVER['HTTP_REFERER'];

to view this referer address. It’s that simple, so the referer is not reliable. Data.
