我已经编写了一个PHP脚本，用于检查是否已将ip写入.dat，如果ip在文件中，则将用户重定向到google。如果没有，它会让他们继续注册我的网站。
以下代码检查控件是否已打开。我把它放在index.php
中 if($One_time_access==1)
{
$fp = fopen("blacklist.dat", "a");
fputs($fp, "\r\n$ip\r\n");
fclose($fp);
}
然后下面的代码完成所有的工作来弄清楚ip，禁止什么等等

我想知道： 1.我可以将ips写入文本文件而不是.dat吗？ 2.有更简单的方法吗？/更短的脚本？
所有帮助将不胜感激：）
