PHP uses curl to implement the method of spoofed IP source _php skill

The example of this article describes the way in which PHP uses Curl to implement spoofed IP sources. Can be achieved to forge IP sources, counterfeit domain names, counterfeit user information, to share for everyone's reference. The implementation methods are as follows:

Define spoofed user browser information http_user_agent

Copy Code code as follows:

$binfo =array (' mozilla/4.0 compatible; MSIE 8.0; Windows NT 5.1; trident/4.0. NET CLR 2.0.50727; infopath.2; asktbptv/5.17.0.25589; Alexa Toolbar) ', ' mozilla/5.0 (Windows NT 5.1; rv:22.0) gecko/20100101 firefox/22.0 ', ' mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; trident/4.0;. net4.0c; Alexa Toolbar) ', ' mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ', $_server[' http_user_agent ']);
123.125.68.*
125.90.88.*

Define spoofed IP source segment, here I'm looking for the IP address of Baidu

Copy Code code as follows:

$cip = ' 123.125.68. ' Mt_rand (0,254);
$XIP = ' 125.90.88. ' Mt_rand (0,254);
$header = Array (
' Client-ip: '. $cip,
' X-forwarded-for: '. $XIP,
);

Using curl to start sending bogus information to the server

Copy Code code as follows:

function Getimgs ($url, $userinfo, $header)
{
$ch = Curl_init ();
$timeout = 5;
curl_setopt ($ch, Curlopt_url, "$url");
curl_setopt ($ch, Curlopt_httpheader, $header);
curl_setopt ($ch, Curlopt_referer, "http://www.baidu.com/");
curl_setopt ($ch, Curlopt_returntransfer, 1);
curl_setopt ($ch, Curlopt_useragent, "$userinfo");
curl_setopt ($ch, Curlopt_connecttimeout, $timeout);
$contents = curl_exec ($ch);
Curl_close ($ch);
return $contents;
}

Get the data and we'll save it.

Copy Code code as follows:

function Saveimgs ($handle)
{
$fp = fopen (' a.jpg ', "w");
Fwrite ($fp, $handle);
Unset ($FP);
Unset ($handle);
}

Testing spoofed IP instances

Copy Code code as follows:

$url = ' yun_qi_img/logo.gif ';
$u = $binfo [Mt_rand (0,3)];
Saveimgs (Getimgs ($url, $u, $header));

So in your current directory to save the success of a file A.jpg file, I can now see the server log is not our customized user information?

See it, exactly, ah, just the IP address I did not test out, this use of PHP to obtain an IP address will show me fake IP address.

I hope this article will help you with your PHP program design.
