有个前提条件是我们的页面必须是php类型的页面,如果你生成了html静态页面这种方法就不可行了,下面我们来看看php实现禁止IP段访问网站的代码,代码如下:
- <?php
-
- if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
- $userip = getenv('HTTP_CLIENT_IP');
- } elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
- $userip = getenv('HTTP_X_FORWARDED_FOR');
- } elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
- $userip = getenv('REMOTE_ADDR');
- } elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
- $userip = $_SERVER['REMOTE_ADDR'];
- }
- $ban_range_low=ip2long("217.0.0.0");
- $ban_range_up=ip2long("217.255.255.255");
- $ip=ip2long($userip]);
- if ($ip>$ban_range_low && $ip<$ban_range_up)
- {
- print "Banned";
- exit();
- }
- ?>
