使用.htaccess隐藏.php扩展名会将访客IP更改为服务器IP

Question

I've noticed that when using Apache(htaccess) to hide .php extension is actually changing the return of the $_SERVER['REMOTE_ADDR']; from returning the visitors IP to returning the Domain or the server IP.

RewriteBase /
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

that's what I'm using for my htaccess file and nothing that

<?php
echo $_SERVER['REMOTE_ADDR'];
?>

in my php file is there anyway that could fix the return of $_SERVER['REMOTE_ADDR'] to be a visitor ip?

Answer 1

Firstly to echo deceze's comment - this is weird, and I don't think caused by the Apache / htaccess rules here. Is there more going on?

Try using:

if(isset($_SERVER['HTTP_X_FORWARDED_FOR']) && $_SERVER['HTTP_X_FORWARTDED_FOR'] != '') {
    $ip_address = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $ip_address = $_SERVER['REMOTE_ADDR'];
}

echo $ip_address;

Does that give a more accurate IP at least?
