我们用下面的函数根据判断来获取客户的真实IP地址哦,好了费话不说多了来看看这款php 取得客户真实IP地址的程序代码吧。

<script>ec(2);</script>

if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown'))
{
$PHP_IP = getenv('HTTP_CLIENT_IP');
}
elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown'))
{
$PHP_IP = getenv('HTTP_X_FORWARDED_FOR');
}
elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown'))
{
$PHP_IP = getenv('REMOTE_ADDR');
}
elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown'))
{
$PHP_IP = $_SERVER['REMOTE_ADDR'];
}
preg_match("/[d.]{7,15}/", $PHP_IP, $ipmatches);
$PHP_IP = $ipmatches[0] ? $ipmatches[0] : 'unknown';
/**
函数 getenv() 是获取环境变量。  环境变量: HTTP_CLIENT_IP 是获取客户端的IP 。但有可能人家是通过代理来访问你的程序的呢。那么这时候就要用 环境变量:
HTTP_X_FORWARDED_FOR  了。 包括  getenv('REMOTE_ADDR')  $_SERVER['REMOTE_ADDR']  都是获取人家  IP的。反正碰罗。碰到那个能获取就大工告成。
