求救PHP获取IP的方法，用getenv(remote_addr);提示出错

[PHPxuexi]

rt

[surfchen]

echo $_GET['REMOTE_ADDR'];

另：错误提示是什么？？？？

[-神仙-]

echo $_SERVER['REMOTE_ADDR']

你用phpinfo输出上面有很多环境变量。
有端口。有host

sorry~神仙是对的，我把SERVER写成了GET~~

[littlejc2]

$_ENV["REMOTE_ADDR"]这个试试呢

[shysky]

unset($onlineip);
if($_SERVER['HTTP_CLIENT_IP']){
$onlineip=$_SERVER['HTTP_CLIENT_IP'];}
elseif($_SERVER['HTTP_X_FORWARDED_FOR']){
$onlineip=$_SERVER['HTTP_X_FORWARDED_FOR']; }
else{$onlineip=$_SERVER['REMOTE_ADDR'];}

echo $onlineip;
