Phpcurl: Counterfeit IP source program implementation code _ PHP Tutorial

Phpcurl spoofs the IP source program implementation code. Today, I have nothing to do with my own phpcurl to forge the IP source program instance program. here, I can forge the IP source, counterfeit the domain name, and forge user information. For more information, see. Define today nothing to do I have written a php curl counterfeit IP source program instance program, here can forge IP source, counterfeit domain name, counterfeit user information, a friend who needs to know can refer.

Define false user browser information HTTP_USER_AGENT

The code is 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/123456 ', '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 the source segment of the forged IP address. here I am looking for the IP address of Baidu

The code is as follows:
$ Cip = '1970. 123. 68. '. mt_rand (125 ); $ Xip = '1970. 90. 88. '. mt_rand (125 ); $ Header = array ( 'Client-IP: '. $ cip, 'X-FORWARDED-FOR: '. $ xip, );

Use curl to start sending forged information to the server

The code is 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; }

We can save the obtained data.

The code is as follows:
Function saveimgs ($ handle) { $ Fp = fopen('a.jpg ', "w "); Fwrite ($ fp, $ handle ); Unset ($ fp ); Unset ($ handle ); }

Test counterfeit IP Instances

The code is as follows:
$ Url = 'http: // www. bKjia. c0m/img/logo.jpg '; $ U = $ binfo [mt_rand (0, 3)]; Saveimgs (getimgs ($ url, $ u, $ header ));

In this case, you have saved a.jpg file in your current directory. can I check whether the server log is our custom user information?

I can see it. it's completely correct, but I didn't test the IP address. when I use php to obtain the IP address, it will show that I forged the IP address.
