本文实例讲述了PHP采用curl实现伪造IP来源的方法。可以实现伪造IP来源,伪造域名,伪造用户信息，分享给大家供大家参考。具体实现方法如下：
定义伪造用户浏览器信息HTTP_USER_AGENT
192.168.1.108 - - [22/Jul/2013:10:29:37 +0800] "GET /test.PHP HTTP/1.1" 200 1244 "-" "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)" 192.168.1.108 - - [22/Jul/2013:10:29:37 +0800] "GET / HTTP/1.1" 200 40538 "http://www.baidu.com/" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET4.0C; Alexa Toolbar)" 192.168.1.108 - - [22/Jul/2013:10:29:37 +0800] "GET /test.PHP HTTP/1.1" 200 1244 "-" "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)" 192.168.1.108 - - [22/Jul/2013:10:29:37 +0800] "GET / HTTP/1.1" 200 40538 "http://www.baidu.com/" "Mozilla/5.0 (Windows NT 5.1; rv:22.0) Gecko/20100101 Firefox/22.0"
看出来了吧，完全正确啊，只是IP地址我怎么没测试出来，这个使用PHP获取ip地址时就会显示我伪造IP地址了。
希望本文所述对大家的PHP程序设计有所帮助。
