php教程获取访问者真实ip地址
在很我的时候我们需要得到用户的真实ip地址,例如,日志记录,地理定位,将用户信息,网站数据分析等,其实获取ip地址很简单$_server['remote_addr']就可以了。
*/
//最简单的方法

$ip = $_server['remote_addr'];

//上面的方法只要使用了代理你就无法得到真实ip地址,下面有更详细的方法

echo "remote addr: " . $_server['remote_addr']."
";
echo "x forward: " . $_server['http_x_forwarded_for']."
";
echo "clien ip: " . $_server['http_client_ip']."
";

//好了来看一个实例。

function getip() {   
 $ip = $_server['remote_addr'];    
 if (!empty($_server['http_client_ip'])) {       
  $ip = $_server['http_client_ip'];   
 } elseif (!empty($_server['http_x_forwarded_for'])) {       
  $ip = $_server['http_x_forwarded_for'];   
 }   
  return $ip;
}

/*
如果是是加密的代理是无法获取真实ip地址的。
